A Tale of Two NL Central Pitchers (Game Recap: Cubs 1, Mariners 8)
Has the league finally figured Randy Wells out?
Wells has never struck many batters out, and he doesn't walk too many, either. He's a control guy that pounds the corners with pitches that move, hoping to get lots of ground balls into the gloves of his defenders. In 2009, he was able to do that with great success, posting a 47.9 GB%.
Unfortunately, Randy has been allowing many more base hits lately. In his last six starts (including an appearance against the Cardinals in which he was unable to record an out), Randy has allowed 45 hits in 28.1 innings pitched.
I know what you're thinking: a ground ball pitcher allowing more base hits must mean Randy's BABIP allowed is out of whack. And indeed it is; this year, Wells has a .361 BABIP allowed, compared to last year's .294.
But it's not ground balls that are turning into hits; it's squared-up line drives. Randy's line drive percentage is up nearly 40% this year relative to 2009, and now stands at 24.7% -- which puts him at the top of the leaderboard among qualified pitchers.
Curiously, however, Wells isn't the only NL Central pitcher to see his LD% spike up this season. The same thing has happened to Milwaukee ace Yovani Gallardo, whose LD% stands at 23.1%.
So if batted ball statistics are to be considered useful, how is Gallardo managing a 2.59 ERA this season while Randy's ERA is up at 5.21?
The answer likely lies in LOB%, or strand rate. For Yovani, 20.9% of the base runners he allows come around to score; for Randy, that number is more than doubled -- 44% of the batters that reach base against him eventually score.
Will Randy's strand rate come down? Convention says yes; historical data shows that LOB% rates tend to be closer to Gallardo's rate than Wells' over the course of a season for most major league pitchers. But with recent reports about Larry Rothschild working with Randy on his mechanics with runners on, I'm not so sure this is something that will just go away as Wells pitches more innings.
Oh yeah, and about last night's game: Cliff Lee is really good, Tyler Colvin is pretty great too, and the Cubs are bad. Boom, game set match. Now go watch the World Cup.
