The Cardinals’ sacrifice bunting problem
Monday, September 19th, 2011In the Cardinals’ thrilling victory in Pennsylvania, a Cardinal batter stepped to the plate in the heat of a tense scoreless tie game with the potential winning run on second and gave himself up to bring that crucial runner 90 feet closer to the plate. No, this wasn’t a Mendoza-line-toeing pitcher bunting in the ninth inning against Roy Halladay; it was the Cardinals’ fourth-best hitter, Jon Jay, in the first inning of last Wednesday’s game against the Pirates and Charlie Morton.
With all due respect to Morton, no one is going to confuse him with Halladay. And yes, we said first inning. With one of the club’s best hitters. And, we should add, it’s 2011, not 1911. So what’s going on?
If it were a once-in-a-career jack-in-the-box kind of a surprise play, one might forgive Tony La Russa for putting it on. But unfortunately for the Cardinals in an disappointing season, the boneheaded sacrifice bunt has become all too common. Of the team’s 93 sac bunt attempts so far this season, eight of them have come in the first inning (about 9%) and more than a third have come in the first three innings:
Anyone familiar with win expectancy knows that bunting in the first inning is already the worst time to attempt what amounts to a very dubious-in-general strategy like sacrifice bunting. Not only is the opportunity cost highest in the first inning (the opportunity to score more than the one run that bunting limits a team to), but it almost always means that someone who should not be bunting — that is, a decent hitter — is doing it.
And that’s exactly what happened Wednesday. If you don’t believe it, even when the bunt “succeeded,” the Cardinals lost 0.02 win probability. Let us repeat: The strategy went as well as planned, and it hurt the team’s chance of winning the game. (To make it worse, Jay, a left-handed batter, was facing Morton, about whom we wrote earlier in the week has a tremendous disadvantage against lefties, of which Jay is one.)
And that has been the story all season: The team has a net -1.75 WPA in all of its sacrifice bunt attempts, most of which were executed according to plan. To contextualize that, it has taken all of Yadier Molina’s efforts this season (and then some) just to nullify the win-expectancy damage that sac bunting has done. Even without the group of pitchers (for whom a case can be made that bunting is a better alternative) who have bunted, the team has a net -0.70 on the season.
For all the lament about how many double plays the team has hit into this season, we’ve heard nary a peep about a demonstrably negative strategy that the team willingly (or at least its manager) undertakes. For a manager who prides himself on knowing all the angles and doing whatever it takes to win, this is a shockingly frustrating and recurring self-inflicted wound. Doesn’t St. Louis deserve better?
