Why should you try to fix it when one of the top pitchers in the league has turned into the team's worst starter? One reason you might want to fix it is that the lower arm angle makes breaking balls break horizontally (staying in the same plane) instead of vertically. Also, it's pretty obvious that Zambrano is walking quite a few more batters than he used to. Maybe you need to work on it Larry. Zambrano has never been a great April pitcher, so it's difficult to differentiate how the angle is affecting him versus what other factors usually contribute to his April woes. I think you're overstating it when you say it's making his breaking balls break on a horizontal plane. It's not like he's dropping 90 degrees down into a sidearmer, and his problem isn't his breaking balls. He throws a sinking fastball that doesn't have the same action, plus he tends to leave more balls up when he drops down. That's the problem. Actually, he had a bad April last season, an ok one in 05 and a great April in 04 and 03. 05 was no good. He put up his second worse ERA of any month in april that year, 4.31 (not bad for some, not good for Zs standards). In 04, he wasn't bad (3.55), but comparatively speaking, April was again his second worse month, barely beating out August by only .07 runs on the ERA. If 07 follows trend, and I think it will, this will be 4 years in a row where April is either his worst or second worst month of the season.
