Marte was 0-1 with a 15.19 ERA in seven appearances for New York this season, but he had not pitched since giving up a walk-off homer to the Red Sox's Kevin Youkilis on April 25 in Boston. Marte was frequently seen in the Yankees' clubhouse icing his shoulder, even on days when he had not thrown.
"I feel weak," Marte said. "We need to do exercise and work out and make it strong. I was working with the trainers. I felt that I needed to go on the DL because I had a couple of weeks to fix up my shoulder."
The Yankees said that Marte underwent an MRI exam on Friday and would see a physician again on Monday, and manager Joe Girardi said that the tendinitis could be a lingering after-effect of Marte's participation in the World Baseball Classic. Marte returned from the Classic saying his shoulder felt tight after lifting weights in the Dominican Republic.
"It's a concern, because he had a problem this spring and we haven't gotten past it," Yankees general manager Brian Cashman said. "We're going to obviously do everything we possibly can. Unfortunately, we have to DL him in-season to try to rectify it now."
In a corresponding roster move, New York recalled right-handed reliever Anthony Claggett from Triple-A Scranton/Wilkes-Barre. Claggett was 2-0 with one save and a 4.26 ERA in seven appearances with Scranton/Wilkes-Barre this season, and he will be making his second stint with the Yankees.
"It's definitely a blessing," Claggett said. "It's a good opportunity. Just coming in today, I'm a little more comfortable with my surroundings. I know what to expect, so I hope it goes better. I'll definitely be ready."
The 25-year-old made his Major League debut on April 18 against Cleveland, allowing eight runs and nine hits in 1 2/3 innings of relief, coming in after starter Chien-Ming Wang was shelled for eight runs.
"About a week after, I watched it," Claggett said. "I watched some of the pitches they hit. I wanted to see it anyway, but I learned some things from it: the quality of pitches I need to throw instead of the ones I didn't throw."
The move leaves the Yankees without their two main eighth-inning options coming out of Spring Training, as Brian Bruney is also on the 15-day disabled list.
"It's going to be a mix-and-match, and it's something that we have to deal with," Girardi said. "It's not how you draw it up, that's for sure. But it's the reality of the game. There are injuries, and we have to find a way to deal with it."
In other injury updates, outfielder Nick Swisher (bruised right elbow) was not in the posted lineup for Sunday's game against the Angels, which was eventually rained out.
Girardi said that Swisher could have been used as a late-inning pinch-hitter and expected him to be available Monday, when the Yankees are scheduled to open a two-game series with the Red Sox.
"It feels better today right now," Swisher said. "[But] it doesn't feel like I could move it."
