CHICAGO >> Carl Crawford continues to make progress in his rehab from a strained oblique muscle, Dodgers manager Don Mattingly said Monday. Crawford is swinging a bat and running curved lines, and could be playing in rehab games soon.

However, the manager offered no assurance that Crawford will be the Dodgers’ starting left fielder once he returns to the Dodgers.

“I haven’t thought about where (Crawford) fits in,” Mattingly said. “Andre’s kind of taken that spot.”

Ethier, who was not in the starting lineup Monday against a left-handed starter, entered the week batting .275 with a .353 on-base percentage. His .487 slugging percentage was higher than any he’s posted in a full season since 2010.

Crawford was the starting left fielder before he got hurt on April 27. The Dodgers used a platoon of Scott Van Slyke and Alex Guerrero in left field at first. When Yasiel Puig returned from the disabled list earlier this month, Ethier shifted from right field to left and has been the everyday starter since.

“It’s not Carl’s fault he got hurt,” Mattingly said. “He had to work his way in. You never know who the odd man out is. … We may platoon a couple spots in the outfield.”
