Now Pitching for your Angels, Sean O'Sullivan

New, comments

I just took a look at O'Sully's 2010 Pitch F/X data from earlier this season as a preview for tonight, and here's what I found:

  • Out of the pen, his fastball averaged 91 mph, up a tick from where he sat in 2009. It's unclear whether that will carry over as a starter. He still gets a lot of backspin on his fastball, causing it to "rise" slightly more than average, so look out for the flyballs if he can't hit his spots down in the zone.
  • By the numbers, his curveball has tighter spin and better-defined 12 to 6 shape than it did last year, dropping almost a full three inches more than the 2009 version.  While the extra break is encouraging, it, like his fastball velocity, might just stem from shorter outings out of the bullpen.
  • Like last year, his changeup is far and away his best pitch, with nearly 14 mph separation from his fastball. His 2009 whiff rate with the change was a solid 15%. It's a good weapon against the left-leaning Yanks.

I like O'Sullivan a lot, and think he has more than a fighting chance against the stacked Yankee line-up, regardless of what the 4.76 Salt Lake ERA would indicate.
