For Troy Tulowitzki, the standings are a reflection of what he sees in the mirror. He's not playing well, and not surprisingly, the team has followed suit. "No one is more frustrated than I am with my performance. I understand the criticism. I know what I signed up for," Tulowitzki said. "I can tell you I am working hard to get better." Tulowitzki arrived early Monday to take extra batting practice. He is slumping, hitting too many flyballs, traced to anxiousness at the plate.
