Bunting on Mariano

You may or may not have noticed -- I probably shouldn't point this out in case you missed it -- but I picked the Minnesota Twins to beat the New York Yankees in the ALDS. I had what seemed to me like solid reasons at the time: I really thought that the Twins would be tough to beat at home, and I thought the Yankees starting pitching problems after C.C. Sabathia would bite them.

More than that, I think I once again underestimated something, something I tend to forget until I see the Yankees play again. Then I remember. That something is this: The Yankees the last couple of years (I think) have put together one of the greatest postseason recipes in baseball history:

The recipe is this:

1 dominant starter

9 or 10 good-to-great hitters to wear down opponents.

1 Mariano Rivera

On the negative side, the ingredients will cost you a lot of money ... you can't even find them at Dean at Deluca. On the positive side, this recipe is so good I'm not even sure you need the dominant starter.

Friday, again, we saw how the Yankees win in the postseason. The Texas Rangers improbably built up a 5-0 lead against C.C. Sabathia and the Yankees, and the Rangers were at home, and the crowd was going crazy, and they STILL lost. Why? Well, they lost in part because Rangers kind of lost their minds. Manager Ron Washington went a little bit cuckoo in the eighth inning as he started throwing out relief pitchers the way a spurned lover throws clothes out a window (Washington used five pitchers in the eighth inning though none of the five happened to be his best reliever).* Ian Kinsler (unconvincingly playing the role of "tying run") got picked off first by Kerry Wood in one of the more bizarre base running blunders of recent times. The Rangers players, as the air grew lighter and lighter, seemed to seize up, both at the plate and in the field. And so on.

*After the crazy eighth inning -- when the Yankees scored five to take a 6-5 lead -- announcer John Smoltz said one of the most curious things I've ever heard a baseball announcer say (and that is saying something). He was trying to make the point that the Rangers needed to put the bad inning behind them, realize that things weren't dire, they were only down one run, they could still win the game. It was a good point to make: Don't panic, don't make too much of things. Only this is what he said:

"If someone had told the Rangers they would be down only one run in the eighth inning, they would have taken that."

Huh? Or to be more specific: Huh? The Rangers would have taken being down a run to the Yankees in the eighth inning? Um, I don't think so. I think it was just a misspeak to make the above point, but I think by saying it that way John actually made several other points that he didn't want to make.

But it seems to me that the way teams continuously collapse against these Yankees in the postseason is no fluke and it's no accident and it's no coincidence. This is all part of the recipe. The Yankees bludgeon teams into mistakes the way Tiger Woods used to strangle major championships on Sundays. The Yankees FORCE teams to go out of character, force them to try absurd things, force them to believe that they had better be perfect or they don't have a chance. The Yankees force it, and teams obligingly crumble.

The Yankees mostly do this with their lineup, their non-stop, no-break, every-inning-is-a-threat lineup -- Jeter, Swisher, Teixeira, A-Rod, Cano, Thames or Berkman, Posada, Granderson, Gardner. You can start that lineup almost anywhere, and it's still better than just about any other lineup in the league starting right at the top. When Posada makes the last out for an inning, for example, suddenly the lineup looks like so:

Granderson

Gardner

Jeter

Swisher

Teixeira

A-Rod

Cano

Thames or Berkman

Posada

Great lineup? Absolutely. No, Jeter is not really a No. 3 hitter at this point in his career -- but he's a first-ballot Hall of Famer, and sure enough he smacked two doubles in the last two innings Friday night. But go ahead, play around with it ... almost any combination of those nine hitters makes for a scary inning. Pitchers can work through three innings, five innings, seven innings, but sooner or later odds are that lineup is going to score runs, especially during that modern-baseball-era gap between the starter and the closer.*

*As I write these words, the Rangers have just taken a 5-0 lead over the Yankees in Saturday's game. So, you could say that adding too much Phil Hughes could mess up the recipe. Then again, it's only the third inning.

Here's another way to think about it: Imagine your team, whatever your team is, down a run in the late innings. As a fan, you probably have a certain place in the lineup that you hope is coming up. If you're a Rangers fan down a run, you probably would hope that Josh Hamilton, Vlad Guerrero, Nelson Cruz are coming up. Something like that. A Phillies fan would probably hope to get Chase Utley, Ryan Howard, Jayson Werth up there. A Giants fan needs Aubrey Huff and Buster Posey. Even bad teams, say the Royals, would hope to get David DeJesus and Billy Butler to the plate.

But for the Yankees ... it just doesn't matter. Sure, they might want Teixera, A-Rod and Cano, but it's certainly no problem if they get Posada, Granderson, Gardner, Jeter, Every inning they have the heart of the order up. They come crashing at you like waves hitting the shore.

Then, of course, if they have the lead in the ninth inning they send Mariano Rivera out there and that's that. I don't know how much stock to put into the Mariano Effect -- that teams not only can't hit Rivera but also try too hard in earlier innings because he's always lurking -- but I do suspect that Rivera plays on the mind. I've mentioned before that before the movie Gandhi came out, there was a real push in India to have him portrayed only by a ray of light, that he was too remarkable to be represented by a mere actor. With Rivera, I keep expecting a ray of light to come trotting in out of the bullpen.

So -- a lineup that will eventually get you, the best postseason reliever in baseball history, and (as a bonus) a few hundred million dollars in starting pitching -- I'm not sure why I keep underestimating the Yankees. Even now, as I look ahead, I think the Phillies have the best team in baseball, and that remarkable Phillies starting pitching could neutralize the Yankees recipe. I keep thinking that the Rangers, if they can just get Cliff Lee out there, would have a shot of winning this series in seven games. But, you know what? Until I see someone break this particular Yankees blueprint for postseason success, I should probably assume that no team can beat them over a seven-game series ...

All of this was just supposed to be a prelude to my real question of the day which is this: Is it smart to sac bunt against Mariano Rivera?

I was thinking about this Friday night, of course, because the Rangers bunted. Man on first, nobody out, needing one run to tie, the Rangers' Elvis Andrus got down a successful sacrifice bunt (with two strikes). The Rangers, of course, did not score the tying run, did not even manage to get the runner to third base. But that doesn't mean it's right or wrong.

My first thought was: Wrong. It has to be wrong. We all know how good Mariano Rivera is ... just giving him an out, it seems to me, is like giving Usain Bolt a head start. The only thing you have against Rivera are your three outs ... they are precious, they are rare, and you have to use them absolutely as well as you can. To give them up for one base seems to me a bad deal.

But ... the more I thought about it, the more wisdom I got from wise people like Tom Tango, the more I realized that this topic is a lot more complicated than that.

First, let's state the obvious: Giving up an out for a base, the vast majority of the time, is a lousy deal. This is why you don't see it happen very often -- there were only 1,500 or so sacrifice hits in more than 185,000 plate appearances this year.

The numbers change, but generally speaking (I have been toying with Tom Tango's run calculator to come up with these numbers):

-- With a runner on first and nobody out, a team will score about 42-44% of the time.

-- With a runner on second and one out, a team will score about 40-42% of the time.

Of course, it depends on the quality of hitters coming up, the quality of pitcher on the mound and various other things, but in a mathematically precise world the gaining of second base and losing of an out DOES NOT give your team a better chance of scoring a run. At most, it's a break-even. If anything, it gives you a lesser chance. And, beyond the "how often you score" issue, it DEFINITELY hurts "how much you score." This is why the sac bunt drives so many of us crazy, especially in the early innings, especially when you waste a good hitter by bunting*.

*Interestingly enough, bunting a runner from second to third with nobody out -- a move I very openly despise -- DOES accomplish that one limited goal of scoring more often. A team with a runner on second and nobody out should score 59-61% of the time. But a team with a runner on third and one out score score 67-69% of the time.

Now, I still think this is a lousy move most of the time because your overall expected runs goes down -- this relates to the classic line about how if you play for one run that's what you'll get. But if you are a manager who wants or needs that one run and only that one run, then it seems by the numbers I've run that in many, even most situations, bunting a runner from second to third isn't as bad a play as I've always believed.

OK, so that's the general bunting scenario. But what about a specific question like this one: Is it worth sac bunting against Mariano Rivera in the ninth inning, down one run, in a postseason game. One of the problems with answering this question is that people tend to oversimplify the sac bunt, tend to turn it into a two-part multiple choice issue: Bunt works, bunt doesn't work.

But that's not realitiy. There are several other possibilities -- here are eight of the more common sac bunt possibilities:

1. The runner moves to second, batter's out, sac bunt.

2. The runner is thrown out at second, batter's safe at first.

3. The runner moves to second, batter's safe at first (a single or an error).

4. The runner moves to third on bad throw, batter's safe at first.

5. The runner is thrown out at second, batter's out too, double play.

6. The runner stays at first, batter pops up bunt.

7. The batters fails to bunt on first two tries, hits away two strikes.

8. The batter fails to bunt on first two tries, bunts again foul, strikeout.

Any and all of these are possibilities and each has its own value. A speedy runner who could turn a sacrifice bunt into a single 20% of the time would change the whole formula. A bad bunter who will foul off the first two bunt chances 75% of the time would change the whole formula. And so on.

So let's simplify the Rivera question even more -- let's make it this: is it worth it in the larger sense to give up an out to move a runner to second base against the best postseason closer ever? So for this we assume 100% success rate on the sacrifice bunt, and we also assume the batter is out 100% of the time.

As it turns out, Tom Tango put this EXACT table in The Book -- a Mariano Rivera scoring distribution table. According to the table:

Runner on first nobody one: Team will score 37.4% of the time.

Runner on second one out: Team will score 36.2% of the time.

So that seems to settle things -- your percentages go down. Only, maybe not: As Tom explains, the better the pitcher gets, the percentages get closer and closer until finally, at some point, they flip and you actually have a better chance of scoring with a runner on second and one out than you do with a runner on first and nobody out.

Tom's Rivera chart refers to the 2007 version of Mariano Rivera, when he gave up 3.2 runs per game. It does not refer to his postseason work. In the postseason, Rivera has an 0.72 ERA in 137 innings of work. He has given up two unearned runs on top of that, so he has given up .85 runs per nine innings.

So, with Tom's help -- and by help I mean "Tom did this" -- we calculated some percentages using Rivera's numbers in the playoffs.

If you use Rivera's exact postseason numbers -- this is assuming he is and will be as good as he has been in the postseason -- the math looks like this:

Runner on first nobody out: Team will score at least one run 21.8% of the time.

Runner on second, on out: Team will score at least one run 26.8% of the time.

Even if you tinker with the numbers, make Rivera a bit more hittable, the bunt still works out as a good play.

And there you go. It really does seem that if you need one run against Rivera you do have a better chance of doing it with a runner on second and one out than a runner on first with nobody out. Of course, it's not that simple. How easy is it to bunt successfully against Rivera? Where are the Yankees playing? Who is coming up? And so on.

But I do think that in a game where Ron Washington made some, er, unusual moves, well, I think my initial reaction in the ninth inning was wrong and I think Washington probably made the right mathematical call by having Andrus bunt.

  1. Judging by the flailing swings that came after the bunt, at least they got a runner to second. With Rivera, you wish you could get a hit, hope you can bloop a busted bat or, like this, bunt your man over and start the same "one hand-other hand" conundrum. Lose-lose?

  5. Thing with the Yankees, ahead 7-2 in the seventh and you're in a close game; behind 7-2 and you're toast.

  6. I think the Rangers had at least a little confidence going against Mariano ... this year, Rivera was 0-2 with a 5.79 ERA and 2.14 (!) WHIP in 5 appearances - 7 hits and 3 walks in 4.2 IP. I understand the nature of small sample sizes but 10 base-runners in ~5 IP has some meaning right?

    Don't think Washington didn't do anything but go with the proverbial "book" with this one. Sac the runner to second and hope for a single to tie the game up, go to extra innings, and maybe have a better chance to win the game against a non-Mariano. His players execute and Washington looks like a genius. His players do not execute and Washington is second-guessed for "giving away outs." So go the life of a MLB manager.

  7. The "one dominant starter" part only works if he can still dominate on short rest. C.C. might be the only starter who fits that mold. Even then, it's awfully precarious.

    If the Yankees do make the WS, they'll have 2-4 games with the pitcher batting ninth. I wonder if their lineup will be as formidable without Gardner working as a second leadoff man.

  8. Posted this on the SI blog, but that site still confuses me so I decided to post it here as well.

    Fascinating stuff, although I'm a little confused about how it works.

    Why does the chance of scoring a run on a sac bunt increase as the pitcher gets better? That seems rather counter-intuitive.

  9. "Why does the chance of scoring a run on a sac bunt increase as the pitcher gets better? That seems rather counter-intuitive."

    I think it's because, as the pitcher gets better, your chances of getting a single before you get two outs decrease less than your chances of getting two singles/an XBH before you get three outs. Think of Rivera: bunting and hoping for a bloop hit seems like the best bet because your odds getting multiple hits or an XBH are so small.

  10. Very interesting. Maybe this is why some of the old school dudes are very into small ball. If they played in the 60s and 70s, as many announcers did, they were playing in a low run scoring environment. You had 4 man rotations, complete games galore and so on. If you bunted, that might get you a run here, a run there, and that might've been enough to win you the ball game. They may hold onto that philosophy because that's what they know, even though that style of play became counterproductive in the steroid era.

  11. I would say bunt just because of the amount of bloopers he gives up, so with a man on second they could score.

    ReplyDelete
  12. @ Nate...it's not that the chance increases in the absolute, it's that the chance of scoring with a man on 2nd and 1 out increases relative to the chance of scoring with a man on first and no outs.

  14. As a Braves fan, I can report that Smoltz has been prone to malapropisms for many years. Which leaves open the comforting possibility that he didn't really mean to equate homosexuality with bestiality that one time....

  15. You forgot about the grit quotient, scrappiness-to-size ratio, and the ever-important, hustle gradient.

    In all seriousness, I love this stuff. I feel like because in general sac bunts don't accomplish much offensively leads some lazy people to pronounce that they're ALWAYS bad. Thanks for shedding some light.

  16. Also, Andrus is fast as hell, and the chance of him getting on via bunt single is nonnegligible -- and he's not a very good hitter , so the chance of him getting on base by swinging away is not high. As it was, he was only thrown out by a half-step or so.

    ReplyDelete
  17. Don't forget the possibility of a GDP when you don't bunt. While players generally don't hit into very many DPs over the course of a season (even the league leaders, for example, Billy Butler this year hit into 32 DPs in 678 PAs) if you break that down into DPs in PAs with runners on 1st and less than 2 outs, it becomes quite a high proportion. Thus, Billy Butler this year hit into a DP once every 4.2 plate appearances with a man on 1st and less than 2 outs. Even non-DP machines hit into DPs in these situations 7-15% of the time, so it's not a negligible event.

  20. I've seen varying calculations about whether a runner on second with one out gives you a better chance of scoring the one run than having a runner on first and nobody out, but assuming it's break-even, wouldn't the fact that nobody sacrifices successfully 100% of the time make bunting with a runner on first a definitively losing proposition, at least in the American League where the pitcher doesn't hit? (I appreciate that the bunter could also have a better than expected outcome, such as reaching first successfully, but wouldn't that be relatively rare as compared to (a) being out at first; (b) forcing the runner at second; or (c) getting into a two-strike hole, then swinging away and making an out?

  21. Another thing about bunting in a close game is that it means you can't steal second, which in many cases would be the smarter play. Obviously Moreland isn't a good candidate to steal, and the only guy left on the bench was Blanco, who can't run either. But Rivera has allowed 8 steals with no CS this year, and Posada only threw out 15% of runners. It would be a much better idea to have saved Julio Borbon for a pinch-running situation than to use him as a pinch-hitter.

  22. Hey remember that Arizona had Damian Miller bunt against Rivera after Mark Grace's leadoff single in the ninth inning of a somewhat famous postseason game. That worked out . . .

    ReplyDelete
  23. As a Yankee fan the bunt I found more puzzling was Swisher bunting Jeter to third in the top of the 9th. I understand the though process, that Mo isn't going to blow a two run lead, but I think Swisher proved he is not much of a bunter (which I suspected). Swisher is a good enough of a hitter that you have to have confidence in him to at least hit a grounder/deep fly to the right side. The one thing the Yankee's offense is missing is probably good candidates to sacrifice bunt, but I think they can survive this one short coming.

    ReplyDelete
  24. You also have to take into effect the quality of the hitter. A good hitter should probably swing away, but with Elvis Andrus the decision becomes a no-brainer. Good call by Washington having Andrus bunt, even with two strikes. This might be the one time out of a hundred I support the sacrifice bunt play.

  25. Joe, great article. Will you please manage the Royals after Ned Yost is 30 games under .500 in August 2011? Thanks

  26. The two biggest blown saves of Rivera's great, great career both involved some type of small ball. Damian Miller's bunt in game 7 of the 2001 World Series, mentioned 3 or 4 posts above by some anonymous person, and Dave Roberts' stolen base in game 7 of the 2004 ALCS.

    This jibes with what Joe and Tom Tango came up with regarding the efficacy of bunting on Rivera. It's great to see people using stats to take make more nuanced observations.

    ReplyDelete
  27. Maybe Poz and TTango can report to us on how, when Rivera has given up the tying or winning run in the 9th, it has generally happened. Small ball or big ball? To what sort of batters?

    ReplyDelete
  28. Note that when you bunt, you're not really giving up an out, you're only giving up maybe 35% of an out, because the batter is EXPECTED to make an out 65% of the time anyway.
    Maybe to be fair, we could base it on OPS rather than OBP. So if your OPS is 1.2, you're giving up 1.2 outs, but if it's .700 you're only giving up 70% of an out.

    ReplyDelete
  29. If I remember correctly, in the 9th inning of the 7th game of the 2001 WS, the Diamondbacks bunted twice against Rivera. They got a lead off hit from Grace. The next batter bunted, and Rivera threw the ball into center field (no further advancement). The next batter (Jay Bell) bunted into a force at third. Then came the tying hit from Tony Womack, a hit batter, and Gonzales' walk-off championship hit.

    ReplyDelete
  30. Each of the two cases where "small ball" resulted in beating Mariano were of the "not pure sacrifice result" type. In one case (2001), Mariano failed to get the runner at 2nd because he made a bad throw (thereby "wasting" the out being surrendered by the D-Backs; the other (2004) was the result of a stolen base (thereby NOT "wasting" an out on a sacrifice) followed by a single. I fail to see how either of those outcomes advance the case for "sacrifice is a good idea", even in "some" cases.

    And I would really like to see more detail on the Mariano Rivera simulations. All of the run expectancy matrices I have seen, including those posted by Tom Tango himself and the one for this past season at Baseball Prospectus, indicate a significant decline in run expectancy when both an out and a base are added. For instance (according to the 2010 BP matrix), man on 1st-no outs resulted in 0.85877 runs vs. man on 2nd-1 out resulting in 0.67765, a decrease of over 21%.

    I am still not convinced that bunting in this case is a good idea, any more than I was ever convinced that walking Barry Bonds intentionally (nearly) all the time was a good idea -- and for the same reasons (i.e., the statistics dispute the validity of the idea).

    I am not saying flat-out that I disagree, just that I am not yet persuaded beyond the shadow of a doubt. Can we see some more detail of the calculations, please?

  31. If the runner on first is fairly fast, I'd go for the steal over the bunt against Rivera.

    He used to be pretty good at holding runners on, but seems to not be good at it anymore. In a game the last weekend of the season, the Red Sox stole four bases off Rivera in one inning-- two different runners stole second and third on him. Posada isn't that great at throwing runners out either.
