SEATTLE -- Twins outfielders Denard Span and Ben Revere were both held out of the lineup with injuries on Friday against the Mariners.
Span has been out with a sore right shoulder since Sunday, after trying to make a diving catch in center. Revere, meanwhile, rolled his right ankle while trying to beat out a throw at first base in Wednesday's game against the Tigers.
Span is making progress but isn't quite ready to even serve as a pinch-hitter or pinch-runner off the bench.
"He feels better, but he's not ready to go out there," Twins manager Ron Gardenhire said. "He's going to do some more work in the cage and then get out there in [batting practice] and see what happens. But he's not ready, so we're still a little thin."
Revere's injury is less severe, as he stayed in the game after rolling his ankle and tripled in his next at-bat. He was available off the bench, if needed, and is expected to return to the starting lineup this weekend.
"There's some swelling, a little black and blue today," Twins assistant general manager Rob Antony said. "He's sore, but he's available. He said, 'If you need me, I can play.'"
With Span and Revere out, Darin Mastroianni made his first start in center field while Matt Carson made his Twins debut in right field. Pedro Florimon also made his Minnesota debut, starting at shortstop.
Twins promote outfielder Carson
SEATTLE -- The Twins selected the contract of outfielder Matt Carson from Triple-A Rochester prior to Friday's game against the Mariners. To make room for him on the 40-man roster, Double-A outfielder Rene Tosoni was outrighted.
The moves come after the Twins optioned relievers Luis Perdomo and Jeff Manship on Wednesday, following a 5-1 loss to the Tigers. Minnesota announced reliever Anthony Swarzak would also be activated from the 15-day disabled list, but the club waited until Friday to bring up Carson, who started in right field and batted seventh against Seattle.
Carson, 31, hit .277/.339/.447 in 110 games with the Red Wings. He hit 14 homers and 23 doubles while leading the team with 49 RBIs. He also saw time in all three outfield spots.
"Talking to our people, he's probably been their most consistent guy from day one, offensively and defensively," Twins assistant general manager Rob Antony said. "He deserved this call-up."
Carson last played in the Majors in 2010 with the A's, when he hit .177 with four homers and four stolen bases in 36 games. He's career .200/.210/.370 hitter in 46 games in the big leagues from 2009-10 with Oakland.
"Any time you've been in the big leagues you want to stay there," Carson said. "So spending a couple of years in the Minor Leagues, you question if it's ever going to happen again. So this late in the season to get the call was a treat and I'm excited to help the team out."
Carson, who is expected to add outfield depth, was signed by the Twins as a Minor League free agent before the season.
Twins extend deal with Rochester through '14
SEATTLE -- The Twins and the Triple-A Rochester Red Wings agreed to a two-year player development contract through the 2014 season, both clubs announced Friday.
The Twins and Red Wings have been partners dating back to 2003, but their contract was scheduled to be up after this season. Twins assistant general manager Rob Antony said the Twins were happy to keep their affiliation with Rochester going for at least two more years.
"We're thrilled because No. 1, it's a good baseball city. But overriding everything else, they have great ownership," Antony said. "They have good people, they treat our players extremely well, they're good to work with for us, and the facilities are good. It's a great stadium, they have good fans, so we're very happy."
The Red Wings have played better this season after finishing the last two years with 90-plus losses. They entered Friday with a 65-61 record with 18 games remaining, and have the best record in the International League, dating back to July 1, at 28-16.
"We had two terrible years the last two years, and when you have a good fan base, and good ownership, you try to do what's good for their organization, and they knew we went out and did a lot of things to try to be competitive down there this year," Antony said. "It's paid off, and even though we've had to take a lot of players up here, they've still battled through it and remained competitive. So they appreciate that. I think they like dealing with us, and we certainly feel the same way with them."
