BALTIMORE -- Twins general manager Terry Ryan shed more light on the MRI exam taken on right-hander Scott Baker's right elbow on Friday.

The results of the MRI exam were very similar to the one Baker received last July, when he missed 18 games with a strained flexor muscle.

Baker is set to get a second opinion from Dr. David Altchek in New York early next week, but the Twins are hopeful Baker will be back on the mound soon, after he exited after making just 11 pitches in a rehab start with Class A Advanced Fort Myers on Thursday.

"It's good news," Ryan said. "Depending on what that second opinion says, that's good news on our front. At least there's not any more damage. It's very similar to what it showed last July, which is a good thing. I wouldn't think he has to be shut down at all, but let's wait until we get that second opinion. I don't know exactly what it's going to show. I hope it's about the same."

In the meantime, Baker won't throw off a mound again until he meets with Dr. Altchek. Baker is currently on the disabled list retroactive to March 27, with right elbow tendinitis.

Hendriks scatched from Sunday start

BALTIMORE -- Twins rookie right-hander Liam Hendriks is in the hospital with food poisoning, and will miss his scheduled start against the Orioles on Sunday.

Right-hander Anthony Swarzak, who was stretched out to six innings during Spring Training, will start in place of Hendriks.

Hendriks took part in Friday's Opening Day ceremonies, but felt sick later that night, and was admitted to the hospital early Saturday and will be kept there until Sunday morning.

"It is amazing," Twins general manager Terry Ryan said with a hint of disbelief. "Everything was fine until he got back home. I don't know what he had, but he's still in the hospital. He'll get out tomorrow morning. It's too bad, because the kid did a wonderful job for us this spring. But it shouldn't take too long to get him back out there."

Hendriks, 23, posted a 2.84 ERA during Spring Training, and was slated to start with right-handers Scott Baker (elbow) and Jason Marquis (family matter) unavailable to open the season.

But instead, the Twins will turn to Swarzak, who also fared well in spring with a 2.93 ERA, and was stretched out to be a long reliever or a spot starter.

"I was preparing to be a starter for weeks in Spring Training, and was put in a situation where if they need a spot start, I'd be ready to go," Swarzak said. "It's unfortunate for Liam to be in the situation he's in. I hope he gets better as soon as possible, because he's a pretty good pitcher, and in the big picture we need as many good pitchers on the staff as we can get."

Marquis pitches well in Double-A start

BALTIMORE -- Right-hander Jason Marquis fared well in his start with Double-A New Britain on Friday, allowing just one run on seven hits over six innings against Richmond.

Marquis, who also struck out four and walked none, was optioned to Double-A on Wednesday because he missed two weeks of Spring Training tending to his seven-year-old daughter, who was seriously injured in a bicycle crash in New York.

Marquis, though, will need only one more start in the Minors before he'll be ready to rejoin the Twins. If he continues on his current pace, he'd start on Thursday with New Britain, and would be ready to pitch with the Twins on April 17.

Twins manager Ron Gardenhire said he wasn't surprised by Marquis' impressive outing, as he looked good while throwing 54 pitches in a Minor League game in Fort Myers, Fla., on Tuesday.

"We figured as much after watching him in the Minor Leagues," Gardenhire said. "He's game-on. He'll be pushing the envelope to get back here, I'm sure, which that'll be good for us."

Revere starts in right field on Saturday

BALTIMORE -- The Twins already made one change to their Opening Day lineup in just the second game of the year, as Ben Revere started in right field in place of Ryan Doumit on Saturday against the Orioles.

Twins manager Ron Gardenhire said he decided to start Revere in right because Doumit is slated to catch on Sunday. He added that it wasn't because the Orioles are starting a right-hander in Tommy Hunter, as Doumit is a switch-hitter.

"Doumit hits left-handers too, so I just wanted to play Ben," Gardenhire said. "Doumit is also gonna catch tomorrow. [Tommy Hunter] kind of has some soft stuff. He has a good fastball, but he can flip some curveballs and changeups. And Ben has done pretty well against that. So it gives [Doumit] a chance to breathe, and gives another guy a chance to get in."

Gardenhire, however, wouldn't confirm that Joe Mauer will start at first base on Sunday with Doumit getting the start behind the plate.
