PHOENIX -- After suffering some stiffness in his right forearm, reliever Jon Rauch threw a good bullpen session Sunday and was available for duty on Monday.

Rauch has not appeared in a game since Aug. 26 in San Diego.

"I'm good," he said Monday.

While Rauch was ready to go, it was not known whether Juan Cruz would be available on Monday.

Cruz was unavailable Sunday after suffering flulike symptoms.
