Mauer, Morneau slated for 'B' game action

PORT CHARLOTTE, Fla. -- While the Twins travel to Sarasota to face the Orioles on Wednesday, Joe Mauer and Justin Morneau will stay back in Fort Myers to play in a "B" game against the Red Sox at 9 a.m. CT at Hammond Stadium.

Mauer is set to see his first action at first base, while Morneau is slated to serve as the designated hitter. Twins manager Ron Gardenhire said Mauer and Morneau will likely bat every inning to get more reps at the plate.

So far in Grapefruit League action, Mauer is 3-for-5 with two RBIs, and Morneau is 1-for-5 with an RBI.

"Surprisingly, I'm feeling pretty good at the plate," Mauer said. "But it's only a few at-bats. I've been able to square a couple balls up. That's kind of the goal early on here."

Right-hander Nick Blackburn is also scheduled to start in the "B" game against the Red Sox. He's yet to pitch in a Grapefruit League game, but he tossed a scoreless inning in last week's "B" game against Boston.

Date set for Zumaya's Tommy John surgery

PORT CHARLOTTE, Fla. -- Twins reliever Joel Zumaya is set to undergo Tommy John surgery on March 29 in Pensacola, Fla., the club announced on Tuesday. Dr. James Andrews will perform the operation.

Zumaya, 27, tore his ulnar collateral ligament on Feb. 25 while throwing a live batting practice session on a practice field at the Lee County Sports Complex.

He made the decision to undergo the surgery on Sunday, after deliberating for nearly a week about whether to undergo the surgery to attempt another comeback or retire.

"He's going to have the surgery with Dr. Andrews, and the rehab will probably be out in San Diego," Twins general manager Terry Ryan said. "I don't know if there's anyone in the game who has gone [through] what he's gone through. But, ultimately, it came down to a decision he was going to make. He thought it out for about four or five days, so you know it didn't come lightly to him."

Twins manager Ron Gardenhire was happy to hear that Zumaya is giving baseball another chance, as his career has been plagued by injuries.

This will be his third operation on his elbow, as he had surgery after fracturing his elbow while pitching for the Tigers against the Twins on June 28, 2010, and had follow-up surgery last year that forced him to miss the '11 season.

"If he wants to continue to try and play, I'm all for it," Gardenhire said. "I think he's great. He's a young man. He still has some arm in him, he just has to get it fixed again and see where he's at after the surgery. But good for him. I'm happy for him."

Ryan said that Zumaya is still on the club's 40-man roster, as the Twins have until Opening Day to decide to release him or place him on the 60-day disabled list. He's set to earn only $400,000 of the one-year, $850,000 deal he signed this offseason because he failed to make the Opening Day roster.

"I probably won't make a decision until I have to," Ryan said. "Once you set your Opening Day 40-man roster, if we need space, we'll make a decision on it."

White released from hospital after stress test

PORT CHARLOTTE, Fla. -- Twins first-base coach Jerry White, who spent Monday night in the hospital after experiencing tightness in his stomach and chest, was released from the hospital on Tuesday after undergoing a stress test.

Twins manager Ron Gardenhire said that White is expected to be fine and back coaching first base on Wednesday.

"They checked him out, and everything was good," Gardenhire said. "He should be back in the clubhouse [on Tuesday] and back out on the field [on Wednesday]."

Bench coach Scott Ullger served as first-base coach in White's absence on Monday and Tuesday.
