CINCINNATI -- Reds shortstop Paul Janish's arm felt exactly how it should have on Thursday -- like he had thrown a lot of pitches for the first time in a long time.

Janish was pressed into emergency relief duty in the ninth inning of Wednesday's 15-3 loss to the Brewers. Pitching for the first time since 2003 while attending Rice University, he threw 35 pitches and finished the inning.

"I'm a lot of sore today," Janish said Thursday as he went to take batting practice.

The Reds' first position player to pitch since Lenny Harris on June 1, 1998, Janish gave up five earned runs and five hits with two strikeouts.

"Janish came out of it OK," Reds manager Dusty Baker said. "I was worried about that after the number of pitches he threw. I remember that's how Jose Canseco got hurt. He was throwing sliders. Paulie was throwing fastballs and changeups."

Thursday was supposed to be a day off for the backup infielder, but Janish was pressed into unexpected service again. When Brandon Phillips was scratched because of the flu, Jerry Hairston Jr. went from shortstop to second base and Janish was inserted at shortstop against Milwaukee. Regular shortstop Alex Gonzalez is out with a strained oblique.

Janish was still upbeat about his big league mound debut. He also volunteers to be the Reds' emergency third catcher if the need arises.

"I thought I'd be a lot sorer, but from what I gather from our other pitchers, I'll be more sore tomorrow than today," Janish said. "I enjoyed it. Obviously, it wasn't the ideal scenario for the team, but I enjoyed it."
