Rauch, who gave up two runs on two hits in two-thirds of an inning on Monday, was taken to the hospital following the appearance. He said the sensation he felt on Monday was unfamiliar -- Rauch had debris in his throwing elbow -- and that he initially shrugged it off as normal soreness.
"Everybody's going to have some kind of tenderness and some kind of soreness just because you're going through an unnatural arm motion," Rauch said. "For me, the first time experiencing anything with my elbow I just chalked it up as normal soreness, maybe aggravated it a little bit, but I didn't expect it to get where it did."
Strong outings by starters Johan Santana, R.A. Dickey and Jon Niese against the Cardinals resulted in three straight games without an appearance for Rauch, who took the mound in all three games against the Phillies in the team's previous series.
Manager Terry Collins said establishing some consistency in his workload could help with both his health and effectiveness.
"We need to make sure we try to be a little bit more consistent with his outings," Collins said. "If he needs to stay more consistent we can certainly try to do that."
