FORT MYERS, Fla. -- General manager Terry Ryan said injured outfielders Chris Parmelee, Darin Mastroianni and Oswaldo Arcia could all return to action this weekend.
Parmelee, who was a late scratch from Thursday's lineup because of right groin tightness, could return to action by Sunday against the Pirates at Hammond Stadium.
"He's OK now," Ryan said. "We'll give him another day, but he's fine."
Mastroianni, who has been out since Feb. 28 with tightness in his left hamstring, has been cleared by team doctors and is expected to play on Saturday against the Pirates in Bradenton. Mastroianni who is competing for the center-field job with Aaron Hicks and Joe Benson, was faring well before his injury with a .364 average in five games.
"Mastroianni is ready to go," Ryan said. "I'm anxious to see Mastroianni back to see what he's capable of doing."
Arcia, who is ranked the club's No. 5 prospect by MLB.com, has yet to play in a Grapefruit League game because of a pulled intercostal muscle. He has been taking batting practice and could make his debut on Saturday or Sunday.
"Arcia is pretty close," Ryan said. "Arcia is hitting today, so he's taking the proper steps. I think he'll get in a game shortly."
Pelfrey pleased with second straight scoreless outing
FORT MYERS, Fla. -- Right-hander Mike Pelfrey turned in his second straight scoreless outing in Friday night's 2-0 win over the Red Sox and came away pleased with his results.
Pelfrey, who is only a little more than 10 months removed from Tommy John surgery on May 1, tossed three scoreless frames. He gave up two hits and a walk and struck out five, including three looking.
His command showed improvement, as he said his sinker was the best it has been so far this spring. Pelfrey loaded the bases in the first inning, but he was able to get out of the jam despite not being able to turn a double play on a comebacker from Jonny Gomes.
"I had a really good sinker tonight," said Pelfrey, who has a 3.52 ERA in three Grapefruit League starts. "I think I should've realized that earlier. I think it was all I threw in the second and third inning. It was really good tonight, and I think I can have days like that where it's my strength and I can throw it 90-95 times."
Pelfrey added his elbow has continued to feel great so far this spring and that he felt good enough to go back out for the fourth inning but was told by pitching coach Rick Anderson he had already reached his pitch count limit. Pelfrey threw 58 pitches and is expected to ramp it up to about 75 pitches in his next outing.
"I felt good," Pelfrey said. "I told Andy, 'Hey, I want to keep going after three.' And he just said, 'Next time.' So we'll continue to build it up. It's a process, but I felt strong and didn't feel tired."
Guerra leaves World Baseball Classic due to injury
FORT MYERS, Fla. -- Right-hander Deolis Guerra returned to the Twins' Spring Training complex on Friday after suffering an injury while with Team Venezuela in the World Baseball Classic.
Guerra pitched in an exhibition game for Venezuela against the Mets in Port St. Lucie on Wednesday, and he gave up two runs on three hits in one inning.
Initial reports in Spanish indicated that he injured his right pectoral muscle, but Twins general manager Terry Ryan said he hasn't heard anything from the club's doctors yet. Guerra was set to be checked out by the club's medical staff on Friday.
"I don't want to give the wrong information," Ryan said, "but it's not a secret. He's back home and has some discomfort."
Guerra, who was acquired by the Twins in 2008 in the trade that sent Johan Santana to the Mets, had a 4.11 ERA with 71 strikeouts in 70 innings split between Double-A New Britain and Triple-A Rochester last season.
Guerra's not on the club's 40-man roster, as he was expected to start the season at Triple-A Rochester.
