Dodgers manager Don Mattingly said Ramirez needs to play around four rehab games, which would put him on track to be activated during a three-game series against the Padres at Dodger Stadium that begins on Monday.
"I've got to test [the hamstring] out and see how it feels," Ramirez said Wednesday before the Dodgers' game against the Angels.
Ramirez has played just four games with the Dodgers this season. He began the season on the disabled list, recovering from surgery on his right thumb he underwent to treat a torn ligament sustained while playing for the Dominican Republic during the World Baseball Classic in March. Ramirez returned earlier than projected on April 29, only to strain his hamstring running from first to third base on May 3 in San Francisco.
"I'm just really happy to be in L.A.," said Ramirez, acquired in a trade with the Marlins last July. "I've just got to stay healthy and I think I can do a lot of things for this team."
