Adam Wainwright is full speed ahead for the Cardinals, but Kevin Siegrist has had to back off the throttle.

Wainwright, nursing a tennis elbow condition, threw 35 to 40 pitches at his own pace Wednesday in the bullpen, where he said one usually could catch those tosses with a Kleenex.

“I felt very good. I felt no signs of anything,” said Wainwright, who pronounced himself fit for a start Saturday here against Philadelphia. “It’s official,” Wainwright said.

But lefthanded reliever Siegrist, who also was to have thrown Wednesday, now won’t test his strained left forearm until Friday. Siegrist reported that a nerve issue behind his left shoulder, something he had in spring training, had flared up again “where it just takes a while to warm up,” he said.

“The forearm and everything else is fine but that (nerve problem) fires sometimes,” said Siegrist. “I guess taking time off for my forearm kind of deconditioned my arm, I don’t know. Is that even a word?

“It compresses on the nerve, so when I release the ball, then (the pain) shoots down my arm. On some days it’s been worse than others but we want the whole feeling to go away, so we’ll see how it feels on Friday.”
