HOUSTON -- Chris Colabello, who won the International League Rookie of the Year Award and the Most Valuable Player Award, had a career day on Monday. The Twins infielder/outfielder hit a game-winning grand slam in the ninth inning of the series opener vs. the Astros.
Colabello became the first player in the history of the franchise -- since 1901 -- to hit two homers in a game, including a go-ahead grand slam in the ninth inning or later.
On the other side of the coin, Colabello went 0-for-4 in his Major League debut on May 22 and didn't get his first hit until three days later. He entered Wednesday's finale hitting .202 in 38 games this season for the Twins.
"It's an ongoing battle for a person who hasn't been up here for any length of time," manager Ron Gardenhire said. "Basically, it gets back to doing what got you here to be successful, but also being able to make a few adjustments to what they're trying to do to you, too."
Colabello has had his ups and downs in the field, as well, sometimes on the same play. That was the case when he dropped a throw from second baseman Brian Dozier during a rundown on an attempted double steal in the seventh inning of Tuesday's 9-6, 12-inning win. But Colabello was able to make a clean pickup and throw home for the putout.
"Funny how things happen, sometimes," Colabello said. "I'm just glad everything worked out."
Colabello was called up Aug. 20 when Joe Mauer went down with concussion-like symptoms.
Mauer slated to take live batting practice
HOUSTON -- Joe Mauer was scheduled to take live batting practice on Wednesday at Target Field.
The All-Star catcher, who was placed on the seven-day concussion list on Aug. 20, was transferred to the 15-day disabled list on Tuesday, with the move retroactive to Aug. 20. With expanded rosters in place, Mauer is eligible to return whenever the Twins deem him ready.
Mauer was scratched from the lineup on Aug. 20 after experiencing dizziness during batting practice. He had taken a foul tip off the facemask the night before, causing a minor bruise to his forehead. He has now missed 15 games.
Mauer had been an ironman of sorts until that, ranking second on the team in games played (113), with 73 of those behind the plate.
Twins manager Ron Gardenhire added no further details, stating, "He's coming along."
Twins bullpen racking up the innings
HOUSTON -- The Twins' bullpen put in six innings of work in Tuesday's 12-inning marathon, and in doing so, it surpassed the Toronto Blue Jays (477 1/3) for the league lead in relief innings with 477 2/3.
Six relievers paraded to the mound. Caleb Thielbar picked up the win with two innings of scoreless relief. Only Anthony Swarzak and Ryan Pressly did not see action.
"From early in the season, our biggest thing here that we worried about was blowing up our bullpen, burning them out because they were pitching so well," Twins manager Ron Gardenhire said.
Going into Wednesday's finale vs. the Astros, the Twins' bullpen had compiled a 3.11 ERA, fifth best in baseball.
"Because we've had a lot of guys throwing really well out of the bullpen, we've been able to mix and match as best we can," Gardenhire said. "But they've thrown a lot of innings, all of them."
