Tweaked Twins land on DL

Catcher Joe Mauer and pitchers Scott Baker and Boof Bonser all ended up on the Twins disabled list to start the season. While Mauer's still dealing with his lower back soreness and hasn't played or practiced all spring, the pitchers' problems sound much more serious.

Baker, who was scheduled to start on Opening Day against the Seattle Mariners, has soreness in his pitching shoulder and was placed on the DL retroactive to March 28. Francisco Liriano is expected to start in place of the righthander on Monday. Bonser is recovering from surgery to repair a torn labrum and rotator cuff in his right shoulder."

Minnesota is looking less and less the favorite to win the AL Central, which should have a razor-thin margin for error with several above-average ball clubs.

Fantasy Impact: Mauer's situation is fairly fluid, and he's fallen down the list of a ton of draft boards. He'll continue to slide outside of the top five catchers now that he's going to miss the start of the season and likely needs some rehab at bats in the minors.

Baker's shoulder soreness is not a good thing, and the mid-level fantasy starter falls into limbo. Bonser had relatively zero fantasy appeal, anyway.

Boof goes poof

Scratch Boof Bonser's name from the starting lineup, and perhaps even from the Twins' setup role this season. He's undergoing shoulder surgery and could be out months.

The decision to have surgery comes after Bonser had two MRI exams and a cortisone shot since the end of last season. The exams showed no structural damage, and the cortisone shot, given a few days before Bonser reported to camp, yielded minimal results.

The surgery will be performed by Tampa Bay Rays team physician Dr. Koco Eaton in St. Petersburg.

"They're going to go in and clean up," Twins manager Ron Gardenhire said. "They know that there's a little small spur that's part of the problem. ... There's no timetable right now because first you have to see exactly what happens in the surgery and what else they find. They'll check everything out as they go through it, in a scope fashion."

Bonser's already damaged fantasy value just hit the floor. What happened to this high-end prospect?
