VIERA, Fla. -- After watching his team defeat the Marlins, 11-7, on Sunday afternoon, manager Matt Williams announced that reliever Casey Janssen will have an MRI on his right shoulder on Monday.
Janssen was scheduled to pitch against the Mets this past Saturday, but he had a tough time getting loose, according to the skipper, so he was scratched.
Janssen last pitched Monday, March 23, against the Yankees and allowed two runs in one inning. It was during that game when Janssen felt uncomfortable.
"He will have a test on his shoulder, so we'll look to see where he is at," Williams said. "He is having a little trouble getting loose. So we are going to have a test done on that."
Janssen signed a one-year deal with the Nationals on Jan. 28 to become the team's setup man, replacing Tyler Clippard, who was traded to the Athletics for second baseman Yunel Escobar. If Janssen is not ready for Opening Day, it would not come as a surprise to see right-hander Blake Treinen pitch the eighth inning.
Treinen is having a great spring, allowing no earned runs in 8 1/3 innings with five strikeouts. Last year, Treinen was often used an emergency starter, and he did well, posting a respectable 3.00 ERA in seven starts. However, there are some in the organization who feel that Treinen could be a closer one day.
