Dodgers left fielder Carl Crawford, whose hitting and throwing programs were postponed last Friday, will resume baseball activities tomorrow, manager Don Mattingly said.

Technically that’s one day ahead of schedule. Five days ago Mattingly said that Crawford would be shut down for a week because of nerve irritation in his left arm.

But Crawford has been symptom-free for three days and got the green light to hit off a tee tomorrow.

“He’ll be monitored, though,” Mattingly said. “He’ll be more on a rehab program … the number of swings taken, exactly what he can do. It’ll start there, in the cage. It’ll be controlled.”

If that goes well, Mattingly said that Crawford will be allowed to throw. He had been throwing from up to 90 feet at the time of the setback. Crawford had Tommy John surgery on his left (throwing) elbow last August and has a target of playing by Opening Day, April 1.

“He’s been able to do everything — track balls, stay in shape, running, all the baserunning stuff — everything basically but throw and hit,” Mattingly said. “That’s obviously pretty important stuff, but there are other areas that he’s able to continue to work.”
