ARLINGTON -- An abdominal injury will prevent left-hander Jarrod Washburn from making his scheduled start against the Yankees on Friday night at Safeco Field, but he vows to pitch again before the regular season ends.
"If nothing else, I will get a [cortisone] shot to make it through the end of the season," he said Wednesday. "Baseball has gotten to the point where it isn't much fun right now anyway. The one day it is fun is the one day I get to play, and not to be able to do that would make for a long, long month."
Washburn (5-14, 4.72 ERA) is winding up his third season with the Mariners and said he has no idea when or how he suffered the abdominal injury.
He seemed perfectly healthy in his start against the Indians on Sunday afternoon, holding the Tribe scoreless over 6 2/3 innings.
"I am assuming I did it at some point of the game," he said. "I didn't feel anything that I am aware of, but when I woke up the next morning, it didn't feel right. It was real sore, like a muscle feels after a bad cramp.
"I was hoping that's what it was so I didn't say anything to the trainers. But the first day here, which was two days after I pitched, it was worse. I knew there was an issue there, so I went in and told [head athletic trainer Rick Griffin]."
After a few pokes in the area, Griffin found the problem and Washburn's usual between-start routine was put on hold.
"He doesn't think it was too deep, so hopefully it will heal pretty quickly," Washburn said. "But he said it's one of the few injuries you get that there is just absolutely nothing you can do to treat it. You just have to wait and let it heal itself."
No one is sure how long that will take, but Washburn won't be rushed back to action by the club.
"We will err on the side of caution," manager Jim Riggleman said, "but it's going to be Wash's call, really. When he says he's 100 percent ready to go, then he would pitch. It's going to be up to him."
