"It's still a little bit sore in there, but I'm building strength," said Crawford. "I still have eight days and I hope everything will be fine. The way it's been going, I'll probably keep ramping up every day with more intensity."
Third baseman Juan Uribe, nursing a strained right hamstring since May 8, was back taking infield and batting practice with the club on Wednesday. Mattingly said Uribe is "gaining traction" in his recovery.
Mattingly said catcher A.J. Ellis is a few days behind Crawford with a sprained right ankle but continues to improve. Ellis would be eligible to be activated Sunday, but that's not likely.
