What’s Going On, Michael Pineda?
Michael Pineda is having a hard time right now. Not when it comes to plate appearances ended by the umpire — his strikeout minus walk percentage is 21st in the big leagues, just ahead of Jake Arrieta’s. Usually that’s good enough, since K-BB% was once shown to be the best in-season predictor, and because it’s hard to be bad if you’re striking a bunch of guys out and not really walking anyone.
Usually. But not right now. Not in the Bronx, at least. Because, since 2000, nobody has recorded a K-BB% over 15% (Pineda is at 17.7% currently) and suffered from a worse batting average on balls in play. Nobody has allowed more homers per nine innings in that group, either. After contact, the ball has not been Pineda’s friend.
Still, we might just chalk it up to luck and call it a day. We might, if it wasn’t so obvious from watching Pineda that he’s having trouble with command and that things aren’t quite right.
