The Colorado Rockies reinstated second baseman DJ LeMahieu from the disabled list on Thursday.
LeMahieu was placed on the disabled list on July 21 with a strained left oblique.
The Rockies (58-49) enter Thursday's game against the Cardinals one game behind the Los Angeles Dodgers and Arizona Diamondbacks -- both teams are 60-49 -- in the National League West standings.
LeMahieu, a two-time All-Star, is hitting .278 with eight home runs and 34 RBIs this season in 72 games.
The Rockies sent infielder Garrett Hampson to the minors in a corresponding move.
