MINNEAPOLIS -- Twins catcher Joe Mauer said after Tuesday's 6-4 victory over the Indians that he had not received a cortisone shot in his sore left knee, but manager Ron Gardenhire didn't rule out the possibility of that still happening.

After an MRI on Tuesday ruled out any structural damage in Mauer's knee, Gardenhire said that the catcher might have a cortisone shot to treat the minor tissue inflammation that was causing the soreness.

"He had that dye in there [from the MRI], so I'm not sure if I'm worried about all that stuff or not," Gardenhire said. "I'm just letting him sit on it for a day or so."

Mauer is still considered day-to-day after jamming his left knee in the sixth inning of Sunday's game against the A's. If he were to get a cortisone shot, Gardenhire said that the catcher would likely miss 4-5 games.

Gardenhire knows Twins must keep winning

MINNEAPOLIS -- The Twins may have clinched the division on Tuesday night, but manager Ron Gardenhire stressed Wednesday how important it is for the club to keep winning with the chance at home-field advantage for the first two rounds of the playoffs on the line.

The Twins entered Wednesday with a 91-60 record and they were one game behind the Yankees (92-59) for the best record in the American League. And Gardenhire said that his team will continue to have two goals over the remaining part of the season -- to get healthy and to try to secure home-field advantage.

"I think our record tells you that we play pretty good baseball at home and I think every team does," Gardenhire said. "You look at pretty much every team that's winning their division and they all have great home records. Same thing for us, we've played pretty well in front of our fans and at our home ballpark."

Gardenhire gave many of his regulars a rest after the team's clinching celebration, but he doesn't think that many of them will want to sit out much over the final 10 games of the regular season.

"They're going to want to get right back after it, that's the way it is out there [in the clubhouse]," Gardenhire said. "They want to play, want to win. We know winning more games is important out here. We want to be swinging good and make sure guys get plenty of rest down the stretch. You have to juggle it."

Mijares' struggles concern Gardenhire

MINNEAPOLIS -- The Twins had many reasons to celebrate following Tuesday's win, but one thing that did concern manager Ron Gardenhire was the performance of left-handed reliever Jose Mijares.

Mijares took over for starter Scott Baker in the sixth inning. But he gave up hits to the first three hitters of the inning, including two left-handers. After a double-play ball scored one run, Mijares gave up a double to Luis Valbuena that scored another run and put the Twins in a 4-1 hole.

"Mijares kind of worried us last night, misfiring," Gardenhire said. "He's been pretty decent in his other outings. We're going to have to see a lot out of him in the last few ballgames. We need to see more out of him, let's put it that way. He's got to be better than that."

The two runs allowed by Mijares came after the Twins bullpen had allowed just one earned run over its previous 29 1/3 innings of work.

Heading into the postseason, Mijares is expected to be in the mix as one of the Twins' primary setup men, along with right-handers Matt Guerrier and Jesse Crain, to lead up to closer Matt Capps and other late-inning option, left-hander Brian Fuentes.
