In a corresponding move, the Dodgers activated right-hander Jimmy Nelson from the injured list after he recovered from a left lumbar strain.
Betts’ IL move is retroactive to Thursday and was made just before the start of Sunday’s game against the Colorado Rockies. He last started on July 17 at Colorado and last appeared in a game Monday when he made a pinch-hit appearance against the San Francisco Giants.
The Dodgers had been avoiding an IL move for Betts, initially projecting him to return on Tuesday for the start of a three-game road series against the San Francisco Giants.
Betts is batting .270 this season with an .876 OPS and has 14 home runs with 40 RBI.
Nelson, who has been on the IL twice this season, è 1-1 with the Dodgers in 20 appearances and has a 2.00 ERA.
