Seattle right-hander Bryan Woo was scratched on Tuesday, and the Mariners said they are awaiting results from an MRI on his right arm.

Woo, 24, had been set to face Chicago White Sox rookie Drew Thorp. But he was replaced by Mariners left-hander Jhonathan Diaz.

Woo spent the first month of the season on the injured list with elbow inflammation. He returned on May 10 and went 3-0 with a 1.07 ERA in his first six starts.

Woo did not throw his bullpen this week and "didn’t feel great" on Monday, according to manager Scott Servais. He has been on a limited pitch count this year because of what Servais called "arm stuff" after Woo’s start against the Los Angeles Angels on May 31.

"It’s unfortunate," Servais said. "Where does this go with Bryan? We’ll just have to wait and see. He’s getting some tests done, doctors look at it, and hoping to stay away from an IL stint. But we’ll know more here in the next day or so. I don’t know when he’s going to get injected back into the rotation. I have no timeline or anything like that, we’re just trying to put it together and figure out a way to win the ballgame tonight."
