MINNEAPOLIS -- With record heat in the Minneapolis area on Tuesday, the Twins opted to skip their normal batting-practice session and hit in the cages before the game instead.
The Twins did hold early batting practice, but decided against taking swings outside during their normal time, considering the oppressive heat. According to several reports, Minneapolis-St. Paul Airport recorded a dew point of 82 degrees, which set a record for dew points since records began in 1945.
"It's hot," Twins manager Ron Gardenhire said. "I think we can all see that. You don't have to deal with this too much around here, you usually see it in Baltimore and Texas with the high humidity. So it's a little unusual, and we'll protect these guys as much as we can."
The Twins took the precautions of making plenty of fluids, iced towels and ammonia water available to players during the game.
"It's going to be like that for three or four days, so we'll just have to live with it," Gardenhire said. "We have a day game tomorrow, so they're going to have to definitely hydrate and go from there."
Mauer gets another start at first
MINNEAPOLIS -- Joe Mauer started at first base for the third time in his career and the second time in as many days against the Indians on Tuesday.
Mauer, who played first base in the first game of a split doubleheader before catching the second game on Monday, was given the day off from behind the plate, with Drew Butera catching left-hander Francisco Liriano.
"He's moving pretty good," Twins manager Ron Gardenhire said of Mauer. "We've got him playing first base today. We're trying to take a little load off his legs. He took a beating in that second game. But yeah, he's been coming along swinging the bat. I think his legs are feeling better underneath him, and you can tell the bat head is starting to get out there. He's firing the ball all over the place."
Mauer picked up six hits in eight at-bats on Monday to raise his batting average to .290 on the season. He entered Tuesday's game hitting .393 with a .485 on-base percentage in July.
"I feel pretty good at the plate," Mauer said. "I'm just trying to hold onto that feeling. I'm just trying not to do too much. I'm seeing the ball a lot better, and getting my foot down and feeling a lot more relaxed."
Gardy: No roster move until at least Thursday
MINNEAPOLIS -- Twins manager Ron Gardenhire said it would be until Thursday at the earliest before the club makes a roster move to get another position player back.
After bringing up an extra pitcher to help get through Monday's doubleheader, the Twins will play through at least the next two games with a short bench offensively. Before their series opener with Detroit on Thursday, the Twins could call up an outfielder.
Which outfielder they call up will likely depend on if Jason Kubel is ready to return from the disabled list, where he has been since early June with a sprained left foot.
"I think Thursday would be the first day that [Rene] Tosoni would be eligible," Gardenhire said. "If it looks like Kubes needs to stay a little longer, we could maybe change it out."
If he were available now, Tosoni would likely have been recalled on Monday following the doubleheader. But after being optioned on July 10, he has to spend 10 days with Triple-A Rochester, making Tosoni eligible to return on Thursday.
Matt Tolbert, who was optioned to make room for the extra pitcher, will also not be eligible to return until after at least 10 days with the Red Wings.
While Kubel is the preferred option this week, Gardenhire said he would not rush either Kubel or Denard Span back from rehabbing in Rochester. Through two rehab games, Kubel is 1-for-8 with four strikeouts, and Span is 0-for-6 with a strikeout.
"I'd sure like to see [Kubel] swinging better than he is now," Gardenhire said. "They don't have return flights, I know that. So, we'll do the best we can. We've got to get [Kubel and Span] swinging, though."
Injured Twins at various stages of recovery
MINNEAPOLIS -- Right-hander Scott Baker's bullpen session is scheduled for Wednesday, and the Twins will decide on the next step for him based on how it goes.
Twins head trainer Rick McWane said Baker "felt great" throwing long toss on Tuesday.
"After he throws his bullpen, we'll make a decision on if he needs to go on a rehab," McWane said.
Right-hander Kevin Slowey (abdominal strain) is scheduled for another rehab start on Wednesday in Rochester, with no pitch limit.
Outfielders Jason Kubel and Denard Span continued to rehab at Triple-A as well, with both scheduled to start on Tuesday night. Kubel was set to DH for nine innings, while Span was expected to play seven innings in center field.
Through two rehab games entering Tuesday, Kubel was hitting 1-for-8 with a double and four strikeouts, while Span was 0-for-6 with a strikeout.
