Atlanta Braves outfielder Michael Bourn has been named by 2012 National League All-Star manager Tony La Russa to replace Washington Nationals shortstop Ian Desmond on the N.L.’s active roster for the 83rd All-Star Game, Major League Baseball announced today.

Bourn entered Saturday’s play with a .305 batting average, seven home runs, 32 RBI, 23 stolen bases and 58 runs scored. Bourn, a second-time N.L. All-Star, played in the 2010 Midsummer Classic in Anaheim. Desmond has been replaced due to a left oblique strain, for which he has undergone treatment and rest has been recommended.

Other announcements regarding the All-Star rosters will be made as they become available. The current American League and National League All-Star rosters accompany this press release.
