CHICAGO -- Speculation was rampant that Saturday would be the day left-handed flamethrower Aroldis Chapman would start his big league career, and fan anticipation could be felt all the way from Cincinnati.

An opening was created when the Reds placed reliever Russ Springer on the 15-day disabled list with a strained left hip on Saturday. But instead of Chapman, right-handed reliever Carlos Fisher was recalled from Triple-A Louisville.

"There were a couple of guys that were throwing the ball well and deserving -- especially [Jared] Burton and Chapman," manager Dusty Baker said. "But we needed some length. That's the one thing we were still missing in the bullpen [after] we sent Fish down. We didn't have a guy that could go three innings comfortably and a guy that could save the bullpen for the next day, and the next day. That's what he gave us when he was here before."

Springer, who had an MRI on Friday, said he didn't know yet how long he would be out and was scheduled to see a doctor again on Saturday. He was making only his second appearance for Cincinnati when he was injured Wednesday at Pittsburgh.

Fisher, who has a 6.89 ERA in 13 games over two previous stints in the big leagues, was sent down Sunday to make room for Springer's promotion from Louisville. Fisher is 1-0 with a 1.74 ERA in 25 games for the Bats this season, including a 0.75 ERA over his past 10 relief appearances.

Chapman, the 22-year-old from Cuba, earned his third save on Friday during Louisville's win over Norfolk. He has allowed one unearned run over his past 12 1/3 innings.

"We'll see Chapman soon enough," Baker said. "We want him to tear it up and get real comfortable."

Phillips likely to rest sore foot on Sunday

CHICAGO -- Second baseman Brandon Phillips was unable to finish the Reds' 4-3 win over the Cubs on Saturday because of a sore foot.

Phillips fouled off a first pitch against Justin Berg off of his foot in the top of the eighth before grounding into a double play later in the at-bat. He remained in the game but was replaced defensively by Miguel Cairo for the bottom of the ninth. Phillips finished the game 0-for-4.

"It's hurting him pretty badly. He couldn't move," Reds manager Dusty Baker said. "We have a few guys kind of hobbling right now that we want to get 100 percent before the Cardinals series. So you might see a much different lineup out there [Sunday]."

Harang, Bailey closer to being ready

CHICAGO -- It's the so-called good problem to have, but it's a tough one no matter how you slice it. What will the Reds do when Aaron Harang and Homer Bailey are ready to come off of the disabled list?

Harang (back soreness) pitched another bullpen session on Saturday and will pitch a simulated game in Cincinnati next week. Bailey is three starts into a rehabilitation assignment and has a 1.53 ERA after he threw seven scoreless innings for Triple-A Louisville on Thursday. Bailey has made two starts for the Bats and one for Class A Dayton.

Meanwhile, the Reds have a full rotation and no easy options to remove someone.

"We've got some challenges with [Bailey] and Aaron getting ready to be available to pitch for us here," Reds pitching coach Bryan Price said. "We have to put together our best 12-man staff. Those will be questions that I'm sure between [GM] Walt [Jocketty], [manager] Dusty [Baker], myself and the rest of the staff, we'll have to make. It won't be easy."

Worth noting

For only the second time in his big league career, Reds right-hander Bronson Arroyo hasn't allowed an earned run in consecutive starts, according to the Elias Sports Bureau. Arroyo pitched seven scoreless innings in Friday's 3-0 win over the Cubs. He also registered back-to-back scoreless outings in July 2009. ...
