That is Matt Harrison's ground ball rate so far in the 2012 season. Only two pitchers have done better in all of baseball -- C.J. Wilson and Jason Hammel -- but both have only done it over one start.â†µ
So that's pretty cool. And Joey Matschulat has a good analysis of why over at Baseball Time in Arlington, with heat maps on the lefty's location this year, as opposed to last year.â†µ
For instance, this is what Harrison's location against lefties looks like in 2011 vs. 2012.â†µ
Yeah, that would be how you get a ton of ground balls.â†µ
Matches has more pictures and analysis, so you should give him a read. Then think about how awesome Matt Harrison might be becoming. I'd like to point, as well, that his 9.4% swinging strike rate so far is a good sign that he can get hitters out even if he struggles to locate that amazingly.
