Corey Hart's a big strong guy.
When you throw him a batting-practice fastball, splitting the plate and roughly crotch-high, Hart is perfectly capable of doing terrible things to the baseball.
Which is exactly how he put the Brewers on the board in the top of the third inning, with a leadoff homer well over the fence in left-center field.
As Grant noted earlier, Josh Collmenter lives on his control. When you throw 88 miles an hour with virtually no horizontal movement at all, you have to hit your spots with your fastball, which he didn't. So Corey Hart crushed it.
Fortunately for Collmenter and the Diamondbacks, this isn't a chronic issue. Despite pitching half the time in a great park for power hitters, Collmenter gave up only 17 home runs in 154 innings this season.
He just missed with a pitch. It happens to everybody.
