With outfielder Cody Bellinger going on the injured list and infielder/outfielder Chris Taylor dealing with a sore neck, the Dodgers elected to bring back Pollock on Wednesday against the Colorado Rockies. He had been sidelined since Sept. 5 with a strained right hamstring.
Pollock grounded out in a pinch-hitting role in the sixth inning of the Dodgers' 10-5 loss. The team plans to start him in left field on Thursday.
"Just making sure we have enough position-player coverage," Dodgers manager Dave Roberts said pregame of Pollock's early activation. "AJ was progressing really well -- just to have him available off the bench will be helpful."
Pollock, 33, is batting .296 with 16 homers and 58 RBIs this season.
In other moves, the Dodgers designated right-hander Shane Greene for assignment. He appeared in nine games with a 4.05 ERA and one save.
