Twins place Arcia on DL, but not Willingham

MINNEAPOLIS -- Oswaldo Arcia was placed on to the 15-day disabled list Wednesday, when he was still feeling soreness in his right wrist while testing it out during batting practice on the field before the Twins' 7-4 loss in 11 innings. Outfielder Darin Mastroianni had his contract purchased from Triple-A Rochester, and he will join the Twins in time for Thursday's game against the A's.

Josh Willingham, who has a bruised left wrist stemming from being hit by a pitch from Justin Masterson on Sunday, hit in the cages and is expected to avoid the DL. But Arcia has been out since Friday with his wrist injury, and it hasn't been getting better, so he was put on the DL retroactive to Saturday.

"Willingham is still sore, but it doesn't have that biting pain, so he's heading in the right direction," Twins assistant general manager Rob Antony said before Wednesday's game. "Arcia took a full round of BP and still feels it, so I think there's a good chance we put him on the DL."

With Willingham and Arcia out of the lineup on Wednesday, Jason Kubel started in left field, while Chris Herrmann made his season debut in right field after being recalled from Triple-A Rochester on Monday with Jason Bartlett on the 15-day disabled list with a sprained left ankle.

Herrmann gives the Twins flexibility, as he can play both corner-outfield spots as well as catch and play first base. He got the nod over Chris Colabello, who served as designated hitter after making his first start in right field on Monday. But Colabello worked with the outfielders during batting practice to get more reps in right field.

"[Herrmann] moves around pretty good anywhere we want to put him," Twins manager Ron Gardenhire said. "He had a good spring for us, with a good swing going. And this gives Colabello an extra day to take a few balls out there and see some more balls off the bat. We can kind of mix both of them out there."

Mastroianni will also give the Twins an extra outfielder, and one who can back up Aaron Hicks in center field. Mastroianni was swinging the bat well at Rochester, hitting .450 (9-for-20) with two doubles in four games.
