MINNEAPOLIS -- The Twins received good news on Tuesday, when the MRI on Delmon Young's sprained right ankle revealed no ligament damage.

"It showed some swelling in the ankle and a bone bruise, but the ligaments all look good," Twins trainer Rick McWane said. "So, we're thinking he just went straight forward into the wall with his ankle and just jammed his ankle. He's responded to treatment really well the last few days and can put full weight on the ankle."

Young, who was placed on the 15-day disabled list after he slid into the left-field wall on Saturday, is expected to be ready to return once eligible on July 11.

"They're calling it a bone bruise, so 15 days should be enough, I'd imagine," Twins manager Ron Gardenhire said.

Kubel to DH for Class A Fort Myers on Tuesday

MINNEAPOLIS -- Jason Kubel played in his first rehab game Tuesday night with Class A Fort Myers, going 0-for-2 with three walks while serving as designated hitter.

Kubel, on the disabled list retroactive to May 31 with a sprained left foot, is scheduled to play in the outfield on Wednesday and Thursday before heading to Double-A New Britain, where he'll play three more games, including two in the outfield.

Right-hander Kevin Slowey (abdomen strain) is also slated to pitch three-to-four innings with Class A Fort Myers on Wednesday, before starting with Triple-A Rochester on Monday.

Justin Morneau is also scheduled to have surgery on his neck on Wednesday to remove a herniated disk fragment and a pinched nerve.

Denard Span, who suffered a concussion in a home-plate collision on June 3, took batting practice indoors at Target Field on Tuesday, but isn't quite ready to hit outdoors.

Gardenhire expects Nishioka will improve

MINNEAPOLIS -- Twins manager Ron Gardenhire said he's trying to make sure shortstop Tsuyoshi Nishioka isn't feeling too much pressure in his first big league season, as he's struggled with a .224 batting average and six errors in 17 games.

"I'm not so much worried about it, but I guess you can call it that, but I just want him to stay positive and stay upbeat," Gardenhire said. "I just want to let him know we're with him out there."

Gardenhire, though, said he was confident that Nishioka will be just fine, and said he's not worried about Nishioka in his first season since playing eight years in Japan.

"I think he's having fun," Gardenhire said. "This is a dream of his to come over here and play. No one said it was going to be easy, and I don't think anyone thought it would be easy. There's a lot of work to do and he'll continue to do that."

Twins sign fourth-round pick Summers

MINNEAPOLIS -- The Twins announced they signed fourth-round Draft pick Matt Summers, a right-hander from UC Irvine on Tuesday, and he'll report to the Rookie League Elizabethton (Tenn.) Twins.

Summers, 21, posted a 2.15 ERA over 177 innings pitched with 100 strikeouts and 33 walks in his junior season with the Anteaters.

The Twins have now signed 19 of their 52 picks from the 2011 First-Year Player Draft.
