Mets OF Yoenis Cespedes (hamstring) will begin his rehab assignment with the Single-A St. Lucie Mets on Friday evening.
Cespedes began a running program last Monday and will hit in the three hole in his first game action since the end of April.
"He feels he's getting better," Collins said last week, according to Newsday's Anthony Rieber. "He told me today that the leg's really feeling a lot better. I think everything's on the upswing. He had a big smile on his face. He's glad to be back. I just said, 'Look, when you get started, take it easy in the beginning. See how you feel.'"
Cespedes was hitting .270 with six home runs and 10 RBI before going on the DL.
With Cespedes out, the Mets have been primarily using Michael Conforto, Curtis Granderson, and Jay Bruce in the outfield from left to right.
