Buster Olney seems to think that Pronk's struggles have something to do with getting hit [insider] by a Ron Mahay pitch.

There is a clear statistical crossroad in Travis Hafner's performance, dating back to the moment when Hafner was hit by a pitch thrown by Ron Mahay on April 25, 2007. The following numbers come courtesy of ESPN research monster Mark Simon:

In the 180 games since he was hit by Mahay:

BA: .243
HR: 23
RBI: 107
K: 145
AB: 635 (154-for-635)

He was hitting .373 with five homers and 15 RBIs that season, through and including the April 25 game.

In the year and month leading up to that at-bat, if you go from 2006 through that 2007 game in which he got hit …

Games: 147
BA: .317
HR: 47
RBI: 132
AB: 521
K: 125

That's just bizarre. Hafner bounced back pretty well from that pitch to the face from Buehrle. I can't imagine anything Ron Mahay brought could be any worse.
