Bourn, who lost to David Freese in online voting for one of the final spots, is replacing Washington Nationals shortstop Ian Desmond on the NL roster for Tuesday's game in Kansas City.
Desmond has been dealing with a left oblique strain and is going to use the break to rest. The decision was made Saturday after Desmond consulted with team doctors, management and NL manager Tony La Russa.
Bourn made the NL All-Star team for the second time. He entered Saturday's game at Philadelphia with a .305 batting average, seven homers, 32 RBIs and 23 stolen bases.
Desmond entered play Saturday with a .279 batting average. He hit his 16th homer in the second inning of Washington's game against Colorado.
