Dexter Fowler blamed his balky knee for getting picked off second in Tuesday's game. Fowler missed over a week with a mild sprain behind his left knee and returned to the field on Tuesday. Colorado trailed by one in the eighth when Troy Tulowitzki's liner allowed Nick Punto to double off a wandering Fowler, whose lateral quickness has suffered because of the injury. "It's tough," Fowler said. "I read the ball and paused. Going back, you just freeze. It's tough to get back (with the knee). Tulo hit the ball well."
