While the Yankees’ offense has gotten off to a roaring start, the starting pitching has yet to catch up. They’re allowing far too many hits to drop in, and then they’re allowing home runs on top of those hits. The result is an ERA, 5.72, that ranks third-worst in the majors. Their peripherals look a bit better, thanks to the third highest strikeout rate and a bottom-third walk rate, but they’re still getting plenty of runs dropped on them. Yet it might not be all their fault.
One pitching aspect that stands out is the starters’ BABIP. At .355 its not only worst in the league, but worst by more than 20 points. As I noted in this morning’s post on Freddy Garcia, the BABIP issue is not simply a matter of pure luck. There are other factors that play into this. While poor command is the likely culprit in Garcia’s high BABIP, that’s not necessarily true for the staff as a whole. In fact, part of that huge BABIP number isn’t the pitchers at all.
A quick look at Baseball Prospectus’s team defensive efficiency bears this out in a different way. The Yankees’ fielders in general fare worst in the majors in converting balls in play into outs. When BP adjusts for park effects and converts defensive efficiency into runs, the Yankees have allowed a half run more on defense than the next worst team. They are nearly 14 runs behind league-leading Toronto.
As you might imagine by this point, the infield plays a large role in in this defensive inadequacy. To wit, on ground balls Yankees pitchers have allowed a .309 BABIP against an AL average of .225. That’s not to say they’re any great shakes against fly balls. Against those they have a .196 BABIP vs. the league average of .136. The defensive woes stretch across the entire field. And it’s killing the pitching staff.
No, poor fielding isn’t the only culprit in these inflated BABIP numbers. As with Freddy, command in general is an issue. We saw CC Sabathia with little command of his fastball in his first two outings. Phil Hughes has left many hittable pitches right over the plate. Hiroki Kuroda struggled with his command in his last start against Minnesota. And there’s Garcia himself, of course. So some of the high BABIP is due to the pitchers leaving hittable pitches over the plate. After all, the bullpen BABIP is much lower, at .307, but that’s still well above league average.
(Other evidence for poor defense killing the Yankees includes a league-worst UZR and a fourth-worst DRS.)
The pitching staff has been rightly criticized through the season’s first month. The starters simply haven’t put it together yet. Unfortunately, their fielders are doing them no favors. Both the infielders and the outfielders are not converting balls in play into outs at an acceptable rate. Getting Brett Gardner back will help the outfield, but in the infield it’s tough to fathom a huge improvement. That could be something to watch as the staff regains its form. Can they overcome these fielding inadequacies?
NOTE: Say what you will about Nunez; I expect plenty of “infield defense will improve if they don’t play Nunez” comments. But the Yankees’ problem isn’t necessarily errors. In fact, according to UZR they’re actually in the positive in terms of errors. It’s in the range department that they’re getting killed.
