Castro is out of the lineup for Sunday's game against the Padres.
Castro will be on the bench for a second straight game after a lackluster start to his time with the Rockies. While starting in 13 of Colorado's first 15 contests, Castro has slashed a pedestrian .220/.278/.340 with one home run, one stolen base, seven RBI and eight runs across 54 plate appearances. Edouard Julien will make a start at the keystone in place of Castro, which opens the designated hitter spot up for Hunter Goodman.
