Twins catcher Joe Mauer may be suffering from a hip flexor, but the injury won't keep him out of the lineup.

After Minnesota's Game 2 loss to New York on Friday night, Mauer admitted that he had been sore and had not been running well since Tuesday's tiebreaker victory over the Tigers.

"I think it's a hip flexor," manager Ron Gardenhire told the Star Tribune. "I think when he spun out around first base [Tuesday], he tweaked it a little bit. But as he told me before I left the clubhouse just now, 'I am a catcher, no matter what you say.'

"He said, 'I played with it for this many days, and I will continue to play with it.' But he is a little sore, yeah, just from a lot of 12-inning games, a lot of stress, a lot of baseball."
