It's not often a man with a Gold Glove is red-faced on defense. But Rockies shortstop Troy Tulowitzki is slumping. With a fielding error Monday against San Diego, he has committed four errors this season after being charged with just six a year ago en route to his second consecutive Gold Glove.

"I am trying to top last year's total in one week," Tulowitzki deadpanned before Monday's game.
