PORT CHARLOTTE, Fla. -- Outfielders Darin Mastroianni (sore left hamstring) and Oswaldo Arcia (strained intercostal muscle) are making good progress in their recoveries, according to Twins manager Ron Gardenhire.
Mastroianni, who tweaked his hamstring while checking his swing on Thursday, originally injured his hamstring while playing in the Venezuelan Winter League. But team doctors told Gardenhire the injury isn't serious.
"Mastroianni is coming along just fine," Gardenhire said. "I think it should be [a return] by mid-week for him."
Arcia, meanwhile, pulled his intercostal muscle on Feb. 22 and has yet to appear in a Grapefruit League game. But Arcia, who is ranked as the club's No. 5 prospect and the No. 93 overall prospect according to MLB.com, is expected to get back to baseball activity later this week.
"He's champing at the bit," Gardenhire said. "They're still keeping him slowed down. We know if he goes too early with that thing it could be a long process. So we want it to heal. He's worried about not getting to play over here, but I'm worried about him being healthy."
