The Chicago Cubs placed Kris Bryant on the disabled list Tuesday with left shoulder inflammation.
The move is retroactive to Saturday.
Bryant had indicated that his shoulder soreness was the result of additional time in the batting cage as he tries to bust out of a slump.
"I think it's a result of swinging too much. ... It's been pretty sore for about five days," he said Sunday.
Bryant's OPS in June is .707, 200 points lower than his career average.
