Kazuo Matsui
As Spring Training prior to the 2007 season began, Barmes was informed that recently drafted prospect Troy Tulowitzki would be competing with him for the starting role in '07. After a spring performance that mirrored his unimpressive '06 season, Barmes ultimately lost the Rockies starting shortstop role to Tulowitzki. Subsequently, Barmes began the regular season with the Rockies Triple-A affiliate, the Colorado Springs Sky Sox. After an injury to starting second baseman Kazuo Matsui, Barmes was recalled to the Major League roster on April 15. After wearing jersey number 12 throughout his tenure in the Majors, Barmes switched to number 21 for the '07 season after veteran Steve Finley chose number 12 for the season.
