Perkins to play for US team against Japan

MINNEAPOLIS -- Major League Baseball announced the details for a five-game series against Japan's National Team in November, and Twins closer Glen Perkins said Friday he's on the preliminary roster.

MLB's announcement on Thursday only officially named Robinson Cano (Mariners), Adam Jones (Orioles), Yasiel Puig (Dodgers) and Albert Pujols (Angels) as participants. Rangers manager Ron Washington will serve as manager.

But Perkins said he's on the tentative roster and his teammates Phil Hughes and Brian Dozier have also asked to participate. Twins first baseman Joe Mauer played in the five-game series against Japan's National Team in 2006, which was the last time the series was held. The MLB All-Stars won all five games that year.

"As long as I'm healthy, I should be there," Perkins said. "When I got the e-mail, I asked Joe about it and he said it was awesome."

Gardenhire: 2015 managerial plans still not discussed

MINNEAPOLIS -- Twins manager Ron Gardenhire downplayed a report in the Minneapolis Star Tribune that stated he'll return to manage the club in 2015.

Gardenhire, who is under contract through next season, said he hasn't officially discussed his future with Twins general manager Terry Ryan and won't until after the season.

"I don't pay attention to it," Gardenhire said. "I don't worry about it. I talk to Terry Ryan about it. We'll talk at the end of the year as always. Nothing has been talked about. I worry about that stuff when the season is over with."

Ryan told the newspaper that he expects Gardenhire to return and didn't retract his statement on Friday, but said that nothing has been determined yet.

"There are things need to be discussed and we'll do it at the end of the year like last year," Ryan said. "We still have things to sit down and discuss and make sure he's happy with me and I'm happy with him. There's a lot of season to play here. Let's see how things go. There's no guarantees for anybody's job, including mine."

The Twins entered Friday's game against the Tigers with a 56-70 record and are on pace for their fourth straight season with at least 90 losses.

Gardenhire, who has been managing the club since 2002, is the second-longest tenured manager in the Majors, behind Angels skipper Mike Scioscia. He reached win No. 1,000 earlier this season, joining Tom Kelly as one of only two managers to accomplish the feat with the Twins.
