From the AP:
After the game, Borchard found a $100 bill awaiting him at his locker, not knowing who it was from.
He later learned A. J. Pierzynski had offered $100 to any of his new White Sox teammates that hit a home run off Brett Tomko.
After reading the article, Tomko painted a picture of Pierzynski being gored by a unicorn. Now Pierzynski's out $100, and he's got that to deal with. Winner: Tomko.
