SEATTLE -- Twins manager Ron Gardenhire said Sunday that he has been impressed by recent callups, infielder Pedro Florimon and outfielder Matt Carson.

The two combined for five of Minnesota's nine hits in its 3-2 loss to Seattle on Saturday, and have been providing strong defense with Florimon at shortstop and Carson in right field.

"We'll kind of get a feel for them as we go along, but both of them have been impressive, to say the least," Gardenhire said. "They both have stepped right in, and I'm really not worried about them."

Florimon, who had his contract purchased on Tuesday, has looked smooth at shortstop and picked up his first hit with the Twins on a triple on Saturday.

"He's pretty confident," Gardenhire said. "He kind of quiets the whole position down out there. He's in control and has a good feel for the game. He's made some nice plays over his head. At the plate, I think you saw right-handed, which is pronounced as his best side, you saw him pretty aggressive with a better swing."

Carson, meanwhile, had a career-high three hits on Saturday, and also threw out a runner trying to advance from first to third on a single to right. He joined the Twins on Friday after leading Triple-A Rochester in both games played and RBIs.

"I like what I've seen and like what he can do," Gardenhire said. "We know he's a good defender. You saw him throw a guy out at third base with a pellet. He moves around smooth out there, and offensively, he's taken some swings."

Revere returns to Twins' lineup on Sunday

SEATTLE -- After missing two games with a sore right ankle, Ben Revere returned to the lineup against the Mariners on Sunday, starting in center field and batting leadoff.

Revere rolled his ankle stepping on first base while trying to beat out a throw on Wednesday, but felt much better on Sunday.

The Twins were being extra cautious with Revere, and called up outfielder Matt Carson for outfield depth on Friday.

"We're in a little bit better situation now with Revere healthy," Twins assistant general manager Rob Antony said. "We've got him, we've got [Josh] Willingham, we've got [Darin] Mastroianni, we've got Carson, we've got guys."

Span still ailing with sore shoulder

SEATTLE -- Center fielder Denard Span is still bothered by soreness in his right shoulder, stemming from an awkward dive in center on Aug. 12, and missed his sixth straight game on Sunday against the Mariners.

Span has yet to take live batting practice, as he's been only taking swings off a tee and doing flip drills. He said his shoulder doesn't affect him when he throws, but that it still hurts when he's swinging the bat.

"I just need to get where I can swing without feeling anything," Span said. "I haven't had anything like that yet. Yesterday started off good, and then it started bothering me. I feel like it's moving in a positive way, but it's starting to get a little frustrating, to be honest with you."

The Twins remain hopeful he'll return to the lineup in the next few days, and are avoiding placing him on the 15-day disabled list because they feel he will be able to play before he'd be eligible to return if he was on the DL.

"It leaves [manager Ron] Gardenhire one guy thin on the bench, but Span could pinch-run," Twins assistant general manager Rob Antony said. "He could go in there if we got into a bind. But I don't see the scenario where we'll be in a bind. Maybe the last two days when [Ben] Revere was out we could've been in a bind. But we've gotten past that."
