TORONTO -- The Twins received a scare on Wednesday night when first baseman Justin Morneau was accidentally kneed in the head while trying to break up a double play in the eighth inning of a 6-5 loss to the Blue Jays.

Morneau lay on the ground for a few moments after second baseman John McDonald's knee accidentally hit him in the head when he slid into the bag. The Twins' training staff and manager Ron Gardenhire ran out on the field to check on the first baseman, who appeared to be a little woozy but managed to walk off the field on his own.

Morneau did not return to the field on defense for the bottom half of the inning. Michael Cuddyer shifted over to first base and Jason Repko entered the game in right field.

The first baseman, who is listed as day-to-day, wasn't available for comment after the game, but Gardenhire said the team will have to wait and see how Morneau is feeling Thursday.

"Morneau took a shot in the head," Gardenhire said. "He was a little dizzy out there. We got him out of the ballgame. He said he had to come out."

It was actually the second injury concern of the night for the Twins, as left fielder Delmon Young sprained his left wrist on a collision with center fielder Denard Span in the left-center field gap. Both players were going full bore on a ball hit by Jose Bautista that turned into a two-run inside-the-park home run. To try and avoid a more serious collision, Young slid while Span stayed on his feet, but the two still ended up catching a piece of each other.

"We were both running right for it, trying to catch it, and when we looked at each other, we were too close," Young said. "If we both [kept] standing or both went down we would have collided. I went down, he stayed up, but we both still hit each other."

Young said his left hand caught one of Span's legs. Young was able to stay in the game and finish it. But like Morneau, he'll have to be evaluated Thursday to see if he can play.

Gardenhire has no worries about Mauer

TORONTO -- There have been a lot of questions directed at Twins manager Ron Gardenhire as to where Joe Mauer's power has gone this season.

Gardenhire has repeatedly said that Mauer is hitting more line drives than in past years and the balls just haven't been carrying over the fence or falling. The numbers certainly back up the statement. Nearly 25 percent of Mauer's hits have been line drives, according to fangraphs.com, which ranks among the highest number of his career.

But after Mauer belted his fourth homer of the year in Tuesday's 7-6 victory over the Blue Jays at Rogers Centre, Gardenhire was asked if that long ball could be what the catcher needs to get on a roll hitting balls over the fence like he did last season -- when he hit a career-high 28 homers.

"I wish we could just say, 'Yeah, that's going to get him going.'" Gardenhire said. "He just has to keep going up there and keep putting the swings on them and they'll travel. He turned on that ball. It came in -- and maybe he was looking for a pitch in a certain spot -- and he turned on it, cranked it."

Gardenhire said that he doesn't worry about Mauer, and also doesn't try to give him any sort of hitting advice, either.

"It's kind of like talking to the President about running the country," Gardenhire said. "Joe hits pretty good. I don't think really personally -- and I love baseball and I know a little bit about this and that -- but I don't think I can help his swing. I think he's pretty good."

Slama added to Futures Game roster

TORONTO -- Right-hander Anthony Slama has been putting up stellar numbers at Triple-A Rochester. So the question is: how long might it take before Slama gets his shot with the Twins?

Slama earned one big honor on Wednesday when he was named to the U.S. roster for the All-Star Futures Game on Sunday at Angel Stadium in Anaheim. He'll be one of two Minnesota prospects taking part in the event. Outfielder Ben Revere will also be playing for the U.S. squad.

The Twins originally had a third prospect, pitcher Liam Hendriks, an Australia native, on the World roster but he recently underwent an emergency appendectomy and will miss the event.

As for Slama, he delivered another scoreless inning for the Red Wings on Tuesday night while striking out the side. The closer, who has recorded 16 saves, now has a 1.30 ERA over 48 1/3 innings. He's held opposing batters to a .130 average while striking out 58 and walking 23.

Recently, Slama was named by Baseball America as its top Minor League closer of the first half. Slama is not currently on the Twins' 40-man roster, so a spot would have to be cleared for him to get a call to the Majors, and that could delay his arrival as well.

But the performance has certainly drawn attention within the organization, particularly from manager Ron Gardenhire.

"He's doing it in Triple-A," Gardenhire said. "We've seen [that] in Triple-A quite a few times. That doesn't compute necessarily to the big leagues. With that being said, he's doing everything he can possibly do to get to the big leagues."

Brunansky rejoins Twins as Minors coach

TORONTO -- Former Twins slugger Tom Brunansky has joined the organization's rookie Gulf Coast League team as a coach.

Brunansky was a member of the Twins' 1987 World Series championship team. The right fielder spent parts of seven seasons with Minnesota from 1982-88. He batted .250 with 163 home runs over that span.
