Ramirez exits after 3 pitches with shoulder issue

CHICAGO -- Cubs reliever Neil Ramirez, forced to leave Wednesday's game after three pitches because of discomfort in his right shoulder, underwent an MRI on Thursday. The Cubs expected to have test results Friday.

"The 90 mile an hour fastball was well below his [average], so something was obviously not well with him," manager Joe Maddon said after the Cubs' 5-0 victory, adding the initial diagnosis is "not real positive."

The Cubs are currently carrying 13 pitchers with the callup of lefty Zac Rosscup on Tuesday. They have an off-day Thursday to decide what to do with the roster.

Ramirez started the ninth inning against the Reds and threw three pitches to Joey Votto, all balls. His last pitch bounced on the plate.

"It was like he was trying to get it there," catcher Miguel Montero said. "Something wasn't right.

"He really looked weird to me, the way he was warming up. He made a couple pitches and didn't look too good."

Ramirez was on the disabled list last season because of a sore right triceps.
