68.2%.
↵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.
↵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.
↵For instance, this is what Harrison's location against lefties looks like in 2011 vs. 2012.

Yeah, that would be how you get a ton of ground balls.
↵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.
