NYM@MIN: Mauer takes foul ball to the helmet

OAKLAND -- One day after expressing definitive encouragement in regards to Joe Mauer's return off the disabled list, Twins general manager Terry Ryan flipped the script on Friday and questioned whether the All-Star catcher will see another at-bat before the end of the 2013 season.

"We have 10 left and he hasn't done any baseball activities, so add it up," Ryan said. "We're running out of calendar."

Ryan's sentiments contrast his stark optimism prior to Thursday's series opener in Oakland, where he said, "I'm holding out hope that we ultimately can get him back on the field. So we're working toward that."

He said Mauer's rehab went just as well Friday as it did Thursday, participating in cardio exercises and general rehab, but he's yet to pick up a bat or do any baseball activities. Mauer sustained his concussion off a foul tip on Aug. 19, and it would be presumably difficult to face Major League pitching on such short notice if and when he's cleared to play this season.

"If there's anybody that could do it, it's Joe," Ryan said. "We know that."

Ryan refused to consider whether his return might be sooner if he focused on acting as a pinch-hitter or designated hitter rather than playing a defensive position, calling the notion premature. He also refuted the suggestion of ending the speculation now rather than holding out hope for an appearance in the last handful of games. Minnesota's All-Star catcher, who's batting .324 with an .880 OPS, 11 home runs and 47 RBIs in 113 games this season, has not had an impact test in a week.

"He's still got to work. He's still getting prepared and so forth," Ryan said. "He's getting over the symptoms. That doesn't mean I'm going to strap the gear on him here in three days and sit him behind the dish."

"Our main goal with Joe is that he's 100 percent," he added. "I'm not sure what we'd accomplish."

Sore left wrist keeps Plouffe sidelined

MIN@CWS: Plouffe singles home a run in the seventh

OAKLAND -- The same soreness in Trevor Plouffe's left wrist that resulted in his removal from the eighth inning of Thursday's series opener against the A's has kept him out of Friday's starting lineup.

Plouffe, who went 0-for-5 with three strikeouts Thursday, said he felt pain after the first pitch of his last at-bat before Eduardo Escobar replaced him at third base for the bottom of the eighth. The original source of the pain, however, stems from June, when he played four games for Triple-A Rochester from June 10-14 during a rehab assignment.

This tidbit has apparently been a revelation to both Twins manager Ron Gardenhire and general manager Terry Ryan, who had no idea he had been managing the pain for such a long stretch.

His statistics wouldn't suggest it -- he's recorded eight multi-hit games in his last 17 starts and is batting .300 with 12 extra-base hits in 31 games since Aug. 18 -- leaving Gardenhire to believe the ailment isn't too severe.

"I didn't know he had a wrist problem until yesterday," Gardenhire said. "If you're suggesting that he's been hurt for a while and swinging like this, then I suggest that he hurts his wrist all the time. He's been swinging better now more than ever."

"If it's hurt him for a couple of months, he probably should've brought it to our attention if it's affected him, but I cant imagine it was or he would have," Ryan said.

"It couldn't have bothered him too much or he would've brought it up. He's not one to beg out of a lineup."

Plouffe said he took 30-40 swings in the batting cage -- his normal number -- and participated in batting practice prior to Friday's game. He said he feels fine and will be ready off the bench if need be.

"I'll just trust him," Gardenhire said. "If he tells me he can go up and hit and he takes a few swings out there and everything seems OK, then we'll go from there."
