MINNEAPOLIS -- Outfielder Darin Mastroianni fouled a ball off his left foot during Spring Training and it's still sore, but he is available off the bench, Twins manager Ron Gardenhire said Wednesday.
Mastroianni made the roster as the club's fourth outfielder after losing out to rookie Aaron Hicks to be the club's starting center fielder. He's expected to be used as a pinch-runner and defensive replacement late in games when he doesn't start. He did just that on Wednesday, when he served as a pinch-runner for Josh Willingham in the eighth inning and remained in left field.
But Gardenhire said he wants to be cautious with Mastroianni in the early going, as he's not completely healthy just yet.
"He's fully available," Gardenhire said. "He tells me he can run even if it hurts. So I just want to know if he's available and can do what I need him to do. But he says there is pain involved and can get through it. So it bothers me a little bit."
Mastroianni has been participating in pregame workouts without any issues, but Gardenhire said he can tell he's not at 100 percent. The Twins also have Wilkin Ramirez on the roster as a backup outfielder as insurance.
"I've been watching him," Gardenhire said. "He's running all over, but he's not flying like he normally does. He's not there. But he's still faster than a lot of guys on our team."
Hendriks, Worley, De Vries to pitch in Orioles series
MINNEAPOLIS -- The Twins announced their rotation for their upcoming three-game series against the Orioles. Right-hander Liam Hendriks will start on Friday and will be followed by fellow right-handers Vance Worley on Saturday and Cole De Vries on Sunday.
Worley, who took the mound against the Tigers on Opening Day on Monday, will be starting on normal rest because of Tuesday's off-day, while De Vries is getting pushed back a day because he left his final Spring Training start on Friday with forearm soreness.
De Vries, who had an impressive Spring Training with a 0.53 ERA in 17 innings, threw a bullpen session on Wednesday, but it didn't go as well as he hoped, according to Twins manager Ron Gardenhire.
"He threw a 'pen today, and it just went OK," Gardenhire said. "It wasn't great. He'll throw another one on Friday, and if anything happens, we'll have to do something."
Diamond, Swarzak look sharp in Minor League outings
MINNEAPOLIS -- Twins manager Ron Gardenhire received positive reports on Wednesday about injured pitchers Scott Diamond and Anthony Swarzak, who both pitched in extended spring camp in Fort Myers, Fla., on Tuesday.
Diamond, who is on the 15-day disabled list after having a bone chip removed from his left elbow in December, struck out seven in five innings. He's expected to start again on Sunday for Class A Advanced Fort Myers and could rejoin Minnesota's rotation by April 12 against the Mets.
"Everything went great," Gardenhire said. "He threw about 70 pitches and threw the ball great."
Swarzak, who is on the 15-day DL with two cracked ribs suffered in a horseplay incident with teammates in late January, struck out five in four innings while throwing 50 pitches.
"Swarzak was really sharp," Gardenhire said. "We'll have to make a decision here as we go along."
Swarzak is eligible to return from the DL on Saturday but is expected to make one more Minor League outing, according to Gardenhire. But that next rehab appearance is not yet scheduled because the pitcher had his wisdom teeth taken out on Wednesday.
With Swarzak out, the Twins don't have a long reliever on their roster. But Gardenhire said he feels like he has enough arms ready if a situation arises where he'll need a long reliever early in the season.
"We'll just have to go by committee and work our way through it," Gardenhire said. "A couple innings here, a couple innings there."
