Hairston, who broke his wrist when he was hit by a Dan Haren pitch June 29, took dry swings for the first time Sunday after fielding ground balls and throwing from shortstop Saturday.
He plans to hit off of a tee and take batting practice Wednesday, have a full workout Thursday, then play the first of two or three rehab games Friday.
"Throwing the ball is not really an issue or problem," Hairston said. "Swinging a bat, being in the fire and trying to swing it 100 mph, that's going to be the biggest test. I'll know more after I play in a couple games."
Hairston will tape his wrist and cover it with a pad -- something he is still getting used to -- but will not wear anything obtrusive or uncomfortable. The biggest obstacle to overcome will be generating power in his swing.
"It's a difficult injury because we do everything with our hands -- hitting, throwing and fielding," Hairston said. "I have to be careful with it, but when I'm back, I'll be back.
"I don't want to go just out there and play, I want to be productive. We're at a point in the second half of the season where we feel like we have a legit chance, and I don't want to harm us in any way. When I come back, I definitely want to be productive."
