Jamie Moyer, at 49 years old, has made the Colorado Rockies starting rotation. “It is still Jamie Moyer. It’s the Jamie Moyer that was pitching prior to the arm injury that cost him the entire 2011 season. It’s the same guy,” Rockies manager Jim Tracy said Friday before the team’s spring training game against the Texas Rangers at Salt River Fields. “It’s the same worker. It’s the same professional. It’s the same stuff, same velocity, same pitches. When he’s right, same type of effectiveness. You’re going to venture into this.” Moyer, who is entering his 25th major-league season, posted a 2.77 ERA this spring and beat out 22-year-old Tyler Chatwood and 28-year-old Guillermo Moscoso for a rotation spot. Moyer will start the Rockies’ second game of the season April 7 against the Houston Astros. If he wins, he’ll be the older player in major league history to earn a victory/AP. More here.
