K-Mad does it again...

First start of the year...HE GUONE.

Justin Duchscherer will undergo an MRI on his biceps Sunday.
The A's believe the injury is just a mild strain. If the MRI shows nothing, it's possible Duchscherer could make his next scheduled start Wednesday in Toronto. If he can't make that start, the A's will probably either pull Lenny DiNardo out of the bullpen to take his place or activate Chad Gaudin a couple days early. Gaudin (foot/hip) is slated to make his first start Saturday in Cleveland, but is eligible to come off the DL at any time.
