Zimmerman has no structural damage in shoulder
By Bill Ladson / MLB.com
WASHINGTON -- Nationals third baseman Ryan Zimmerman underwent an MRI on his sore right shoulder Sunday, the results of which revealed inflammation but no structural damage.
Zimmerman, who pinch-hit and struck out in Sunday's 2-1 victory over the Braves, will be reevaluated on Tuesday, according to manager Matt Williams.
"As of right now, he has today and tomorrow off," Williams said. "His swing is fine. The issue he has is probably throwing overload. He throws a lot and he works at it really hard, so it may be a little overload at this point."
In Saturday's 6-2 loss to the Braves, Andrelton Simmons hit what looked like a routine ground ball to Zimmerman, whose high throw to first pulled Adam LaRoche off the bag, with the ball tipping off the first baseman's glove and then bouncing into the stands, allowing Justin Upton to score to make it a one-run game.
Zimmerman was taken out of the game in the top of the sixth inning, and it was revealed that he had a sore right shoulder, which was a problem for him most of last season. Zimmerman acknowledged that the soreness never went away this past Spring Training.
"It's just sore. It was more sore yesterday than it usually is," Zimmerman said on Sunday morning. "Yesterday, I felt worse than normal. I thought it was the right thing to tell Matt, and we'll see what you got."
It has been a tough 2 1/2 years for Zimmerman. Starting in 2012, he had cortisone shots in the shoulder before undergoing surgery after the season. During the 2013 season, Zimmerman had a tough time recovering from the surgery. He had a had a tough time throwing to first until the month of September.
During Spring Training, Zimmerman had shoulder soreness during Spring Training, but the team didn't show any concerns. For now, the Nationals have not placed Zimmerman on the disabled list.
It has become apparent that if the shoulder continues to be a problem, Zimmerman could find himself at first base on a permanent basis. He played a few games at first during Spring Training.
"I don't know if I really thought about [playing first base] yet," Zimmerman said. "Obviously, I would love to play third base. I feel like I've been a good third baseman. We have to assess what's going on and see what we do."
Nats place Hairston on DL, recall Moore
WASHINGTON -- The Nationals placed outfielder Scott Hairston on the 15-day disabled list with a left oblique strain on Sunday and recalled first baseman/outfielder Tyler Moore from Triple-A Syracuse.
Moore played one game for Syracuse this season and was hitless in four at-bats.
Hairston was 1-for-2 before being placed on the DL. He hurt the oblique while taking a swing during batting practice in New York. Hairston told the training staff and he has been treating the injury ever since. Hairston was able to get an at-bat against the Braves on Saturday.
But the more he swung the bat, the more pain Hairston felt. Hairston doesn't expect to be out for longer than 15 days.
Fister has no pain after throwing from 60 feet
WASHINGTON -- Nationals right-hander Doug Fister played catch from 60 feet without any problems on Sunday, according to pitching coach Steve McCatty.
Fister has been on the 15-day disabled list since the start of the season because of a right lat strain, and he missed most of Spring Training because of elbow inflammation.
"He played catch at 60 feet today and he threw the ball fine. No pain -- he didn't feel anything in the back or in the elbow, so that's good," McCatty said. "I'm sure he's encouraged, but he's probably going wacko. He doesn't like sitting here and doing this. He understands and knows there's a process to doing it."
Fister is expected to miss a month of action, so he is not expected to be back on a Major League mound until sometime in May.
• While Nationals shortstop Ian Desmond was happy about driving in the game-winning run against the Braves on Sunday, his biggest accomplishment of the day was that he stopped chewing tobacco during the game for the first time in his life. Desmond made a promise to his mother, Pattie Paradise, early in the day that he would stop dipping. Desmond has been chewing tobacco even since he was a teenager.
"I hate to say this, because I know there will probably be kids that hear this, but for me growing up, it was part of the game." Desmond said.
"That was a bigger victory than beating the Braves. I'm really trying hard to quit. I kind of decided that it was time. It's not going to be easy. I've been doing it for a long time. It's a terrible habit, but I'm working on it."
• Tanner Roark was warming up in the bullpen on Sunday. Williams opted not to use the right-hander, who will likely not start until Friday in Atlanta.
