On Monday, Cincinnati is expected to purchase the contract of veteran right-hander Russ Springer.
Springer, who owns a career mark of 36-45 with a 4.52 ERA in 738 appearances, made seven appearances for Triple-A Louisville, allowing just two hits in 6 1/3 innings. He walked two and struck out five.
"He adds experience," said Reds manager Dusty Baker. "He's been in pennant races, World Series. We're young [in the bullpen]. We need a stabilizer to go along with Arthur [Rhodes] and [Francisco] Cordero."
Springer has made 14 postseason appearances, including four in the World Series -- most recently with Houston in 2005. The Reds signed the 14-year veteran to a Minor League contract on July 15.
Fisher was 1-1 with a 6.89 ERA in 13 appearances.
Springer is expected to wear No. 50.
