Twins placed OF Darin Mastroianni on the 15-day disabled list with a left ankle injury.

Mastroianni probably doesn't need two full weeks of down time, but with Wilkin Ramirez (back) and Josh Willingham (illness) on the shelf, the Twins had to call up an outfielder. Oswaldo Arcia replaced Mastroianni on the roster.

Darin Mastroianni was scratched from Tuesday's lineup with a left ankle injury.

It's the same ankle that he injured earlier this month on a foul tip. He's considered day-to-day. Ryan Doumit has entered the lineup in Mastroianni's place as the DH, while Wilkin Ramirez is taking his spot in left field.

Darin Mastroianni (ankle) said he's progressing but will still likely need a few days before he's ready to start.

The outfielder injured his left ankle on a foul tip on March 25 and re-injured it trying to get loose on Opening Day. He indicated he'd like to be ready for the Twins' next series against the Royals, but it's more likely the start will come the following series against the Mets. When the 27-year-old returns, it remains to be seen what role he will fill with rookie Aaron Hicks currently occupying center field.

Darin Mastroianni went 2-for-4 with a double, and swiped his sixth base of the spring in a losing effort against the Red Sox on Friday.

Despite missing time with a hamstring problem, Mastroianni has done everything in his power to secure a place on the Twins Opening Day roster this spring, hitting .409 (9-for-22). Despite that, he seems to have been passed over by Aaron Hicks as the likely starter in center field. Even in a reserve role, Mastroianni does hold mixed league value with his keen ability to steal bases.

Darin Mastroianni went 2-for-3 with an RBI in his return to the lineup on Saturday.

Mastroianni had been sidelined with a hamstring problem. He's been overtaken by Aaron Hicks as the likely starter in center field for the Twins, but he's still expected to have a roster spot and he could swipe 20 bases as a reserve.

Darin Mastroianni (hamstring) could return to the starting lineup Saturday.

Mastroianni missed a week of action with a sore left hamstring, but he made it through pre-game workouts Friday with no issues. The 27-year-old entered camp as the favorite for the starting center fielder job, but Aaron Hicks has emerged as the favorite in recent days.

Darin Mastroianni (hamstring) went through the Twins' full workout before Thursday's game and has been cleared to return to action.

Mastroianni missed a week of action with a sore left hamstring. Aaron Hicks has been on fire during that week, clearly separating himself from the rest of the pack in the competition to become the Twins' starting center fielder.

Darin Mastroianni's sore left hamstring is expected to keep him out of action until the middle or end of next week.

Despite missing a few more games, the injury is not thought to be too serious. The 27-year-old stole 21 bases in 24 attempts last season, so he'll need the hamstring to be near full-strength to be as effective as he can be going forward. With the offseasoon trades of Denard Span and Ben Revere, Mastroianni is battling for a starting outfield spot this spring.

Darin Mastroianni left Thursday's Grapefruit League game with a sore left hamstring.

It doesn't sound like a major concern, as Mastroianni said it only bothers him when he slows down. Consider him day-to-day.

Darin Mastroianni returned to action on Friday September 28.

Darin Mastroianni will be limited to pinch-running for the final 14 games this season due to a torn tendon in his left middle finger.

He'll end the season with a .252/.328/.350 batting line but could conceivably add to his stolen base total of 21. Mastroianni has probably done enough this season to have a good shot at a bench role in 2013.

Darin Mastroianni had three hits and three steals Thursday against the Tigers.

That's the good news. The bad is that he was caught stealing home having already stolen second and third in the eighth inning. Mastroianni isn't much of a hitter, but he is 8-for-9 stealing bases in 30 games for the Twins. He'd probably be worth using in AL-only leagues if a Twins outfielder gets hurt.

Darin Mastroianni went 0-for-2 with a walk in Wednesday's shutout loss to the White Sox.

His hot start to the season at Triple-A has not translated to the majors, as Mastroianni is batting only 3-for-22 (.136) with zero extra-base hits. The 15-28 Twins are searching for talent wherever they can find it, but the 26-year-old rookie has not yet answered the call.

Twins recalled OF Darin Mastroianni from Triple-A Rochester.

Mastroianni was off to a hot start this season at the Triple-A level, batting .365/.405/.446 in 80 plate appearances. The Twins will hope he can carry some of that offense with him to their bench.

Twins claimed OF Darin Mastroianni off waivers from the Blue Jays.

Mastroianni was designated for assignment last week to make room for Francisco Cordero on Toronto's 40-man roster. The 26-year-old appeared in one game with the Blue Jays last season, but spent the majority of 2011 in the minors, batting .268/.353/.377 with three homers, 36 RBI, 34 stolen bases and a .730 OPS between Double- and Triple-A. He'll likely be ticketed for Triple-A Rochester.

Blue Jays designated OF Darin Mastroianni for assignment.

Mastroianni was cleared to make room for the newly-signed Francisco Cordero on the 40-man roster. The 26-year-old outfielder had three plate appearances with the Blue Jays last season, but spent the majority of the year in the minors, batting .268/.353/.377 with three homers, 36 RBI, 10 stolen bases and a .730 OPS between Double- and Triple-A. There's a chance he'll slip through waivers.

Blue Jays optioned OF Darin Mastroianni to Triple-A Las Vegas.

Mastroianni was given just two major league plate appearances during his short stay in the majors and failed to manage a hit. He could be brought back in early September.

Blue Jays recalled OF Darin Mastroianni from Triple-A Las Vegas.

He'll hold down a roster spot, at least until Kelly Johnson joins the team Friday. Mastroianni, 25, is batting .266/.353/.382 with three homers, 35 RBI, 28 stolen bases and a .735 OPS over 509 plate appearances between Double-A New Hampshire and Triple-A Las Vegas this season. He has some speed and patience, but is unlikely to hold much fantasy value.
