The Hidden Drawbacks of Sweepers

Otani has thrown about 42% of his pitches this year have been sweepers. He throws too many, I think, specifically to left-handed hitters and should be cutting back more than he does. His 208 sweepers to lefties have basically a neutral run value, negative 0.1 So they haven't really been good for him or for the batter. If it's just kind of a break-even pitch, if it's no better for him than it is for the batter Then that's not so great because he should have good run values on probably all of his pitches.
