Thinking the day's workout was over, Ben Petrick turned his back on the field and started to put his catcher's gear in his equipment bag one afternoon this spring. That's when teammate Darren Bragg smacked a one-hopper right at Petrick, hitting him flush in the posterior. The incident was typical Petrick: The ball didn't get past him. "Ben is a great athlete, that's why his future is so bright," says manager Buddy Bell. "All he needs is experience." Last year Petrick hit a combined .313 with 27 home runs and 98 RBIs between Double A Carolina and Triple A Colorado Springs, then hit .323 in 62 at bats with Colorado. Though Brent Mayne will begin the year as the Rockies' starting catcher, it's just a matter of time before Petrick, who turns 23 on April 7, claims the job—for the next decade or so.
