While he is expected to be bypassed for a second straight night should a save opportunity present itself, suddenly-struggling RHP Joe Nathan said Saturday there is no issue with his surgically-repaired right elbow.

Nathan, 37, said that his recent rocky stretch is due to a lack of life on his fastball, which pitchers commonly refer to as "dead arm." Nathan said he would be "down again" on Saturday, though manager Ron Washington said he would not reveal his plans for Nathan.

"It's just been a time of year where I've thrown a lot," Nathan said. "The life on my fastball is a little less. The workload that I've had has been heavy. I want to get to a point where I don't feel like you are fighting to get [the ball] out there. "
