Rafael Soriano will have a precautionary MRI Wednesday on what Joe Girardi called a "tender" right elbow, which has given the pitcher trouble in the past.

Soriano said his elbow hasn't felt quite right the last "couple weeks" and asked for the night off May 2 in Detroit. Girardi used Joba Chamberlain in the eighth inning of that night's 5-3 victory over the Tigers. The Yankees lost three straight after that, and Soriano pitched Friday and Sunday in Texas without giving up a run. He hasn't allowed one in his last four appearances.

Chamberlain pitched a scoreless eighth inning Tuesday night in a 3-1 victory over the Royals.

"I want to make sure everything's fine," Soriano said. "After that, I think maybe one or two days and I'll be back."

But the elbow has given him trouble before. In 2008 he was limited to 14 relief appearances with the Braves because of three stints on the disabled list with right elbow injuries.

"Today I felt a little sore," said Soriano, who threw some long toss Tuesday before telling Girardi he couldn't go. "Little bit . . . I want to make sure everything is fine."
