Mariners manager Lloyd McClendon said starting pitcher Taijuan Walker (shoulder) threw from 120-150 feet Monday, but he wouldn't announce a target date for the right-hander's return to action.

"He threw the ball extremely well. No pain whatsoever," McClendon said. "It’s too early. You don’t want to speed up the process. I know we’re all anxious to him back, but this young man has a long career ahead of him. We’ve got to make sure we do it right."
