From Paul Sullivan's game article:

"He hit it in our bullpen, and [Johnson] caught it," Dempster said. "I've been playing 15 years of professional baseball now, and he's made the two best catches while I've been pitching. I'll have to buy him a [burger] on the way home."

I actually make myself laugh thinking about all the possible un-printable words that may have been said there other than burger...
