Drew Pomeranz exited his spring training debut Friday with what the Red Sox are calling "forearm tightness".

Pomeranz told the Boston Herald's Michael Silverman his level of concern is "pretty low".

Pomeranz: 'Pretty sure this is probably nothing.'

“I felt pretty good in the first inning, just felt a little tightness going out there in the second inning,” Pomeranz said per Silverman. “I threw a few pitches to the first hitter and I wasn’t really pushing it, so I just was like ‘You know what, there’s no point.’ Let’s figure out what’s going on and shut it down.

“It was just something I didn’t feel like pushing in my first outing. I came in here, the trainers checked it out and everything seems fine, so we’ll see how I feel coming in the next couple of days.”

The plan is for Pomeranz to be revaluated on Saturday.
