FORT MYERS, Fla. -- Sean Burroughs was hit by a pitch on the left forearm by Rays right-hander Ryan Reid in the sixth inning of the Twins' 10-4 loss on Monday, and left the game for precautionary reasons.

Burroughs was diagnosed with a left forearm bruise and is day to day. He was replaced by Luke Hughes as a pinch-runner at first base.

"He's OK," Twins general manager Terry Ryan said. "They didn't even take X-rays."

Burroughs, who is competing for a spot as a backup infielder as a non-roster invitee, is hitting .290 with a .405 on-base percentage in 13 games this spring.

Playing DH helping preserve Morneau's health

FORT MYERS, Fla. -- After making his eighth consecutive start at designated hitter, Justin Morneau said that doctors advised him that if he avoids playing first base, it can help reduce the risk of suffering a concussion-related setback.

Morneau, who doubled in Monday's 10-4 loss to mark his third straight game with an extra-base hit, hasn't played first since March 13. He said he hasn't been bothered by any concussion-related issues this spring, but that he's playing it safe by serving as DH for now.

"Not to get into the medical stuff too much, but they said before that if my body gets worn down too much, I'm more vulnerable to having the symptoms reoccur," said Morneau, who suffered his initial concussion in July 2010. "The chance of going backward is when I get worn down. I can have the fogginess and the headaches, and all that stuff can return if my system gets too worn down. Then I'm in a vulnerable position."

Morneau added there's still a chance he may start the season at first base, but he's been able to play more this spring because he's mostly served as DH. He's already racked up 54 at-bats (he's hitting .167 with four extra-base hits) in 13 games.

"It's one of those things where am I in the clear, yes," Morneau said. "But is there still a possibility in the end that things could go backward? A very, very small possibility. So I think that's kind of where the DH thing is based."

Willingham scratched to tend to ankle

FORT MYERS, Fla. -- A day after he was named the Twins' starting left fielder this season, Josh Willingham was a late scratch on Monday with what general manager Terry Ryan called a tweaked ankle.

Ryan said Willingham hurt his ankle a few days ago, but it flared up again during warmups before Monday's game against the Rays.

Willingham was held out for precautionary reasons, as Ryan said the injury is so minor that he didn't even know which ankle it was that was bothering Willingham.

"I don't know, because it's not very serious," Ryan said. "So I don't really care. He did everything [pregame], but unfortunately, he said he tweaked it just a little. So we don't want to mess with that. As usual, he said he could play today, but we didn't want him to play."

Ben Revere started in left field in Willingham's absence and batted seventh. Revere was originally slated to be the club's starter in left this season with Willingham in right, but the Twins opted to make Willingham their left fielder, as that's where he's played most of his career.

Revere is now likely to be the fourth outfielder, with players such as Trevor Plouffe, Ryan Doumit and Chris Parmelee competing for time in right. Plouffe and Doumit are locks to make the club, while Parmelee is gaining momentum after a strong showing this spring.

Ryan added that the Twins won't hesitate to give Revere playing time in right field despite his limitations with his throwing arm.

"It's not an ideal right-field arm, but it's not an ideal left-field arm, either," Ryan said. "But his arm strength is not going to hold him back from making this ballclub. He has other attributes that he provides for this club."

Marquis remains in NY with family

FORT MYERS, Fla. -- Twins right-hander Jason Marquis remains home in New York tending to a family issue, as his 7-year-old daughter was in a serious bike accident last week.

Marquis has been away from Twins camp for six days, and missed his scheduled start against the Rays on Saturday.

The Twins don't know when he'll return, but he's been throwing bullpen sessions back in New York, and he should still be able to rejoin the rotation when he gets back.

"He's still OK, because he's working there," said Twins general manager Terry Ryan. "It's not like he's not doing anything up there. I'm more worried about that girl than I am pitching. That'll take care of itself."

Plouffe set to play in Minors game Wednesday

FORT MYERS, Fla. -- Twins outfielder Trevor Plouffe participated in a workout without any issues on Monday, and is scheduled to play in a Minor League game on Wednesday.

Plouffe, who has been dealing with a strained right hamstring suffered on March 18, was slated to play in a Minor League game on Monday, but he needed a few extra days to let his hamstring heal.

"He did well today," Twins general manager Terry Ryan said. "So he's going to go through the bases tomorrow and then play Wednesday."

Plouffe, who is out of Minor League options, is hitting .276 in 10 games this spring.

Twins send righty Wise to Minor League camp

FORT MYERS, Fla. -- The Twins made one roster move on Monday, reassigning right-hander Brendan Wise to Minor League camp.

Wise, 26, posted a 9.00 ERA over seven innings in six Grapefruit League games. The Australia native struck one, walked one and allowed two home runs.

Wise, who is not on the Major League roster, signed a Minor League contract with the Twins in November.

He spent the previous seven seasons in the Tigers' organization, and has a career 3.37 ERA with 227 strikeouts in 424 1/3 innings in the Minors. In 61 2/3 innings in Triple-A last season, Wise had a 1.90 ERA with 39 strikeouts, 28 walks and three homers allowed.

The Twins now have 38 players in camp: 17 pitchers (two non-roster), five catchers (two non-roster), 10 infielders (four non-roster) and six outfielders (one non-roster).
