Rolen gets one more day to rest shoulder

PITTSBURGH -- Scott Rolen was held out of the Reds lineup for the second straight day Tuesday in order to rest his shoulder, but manager Dusty Baker said the third baseman would be back Wednesday for the series finale against the Pirates.

Baker said he wanted to give Rolen two days of rest, and it made more sense for him to face Jeff Karstens, who is scheduled to pitch Wednesday, than to have faced Tuesday's starter, James McDonald.

"McDonald throws a bunch of high fastballs, and [Karstens] is mostly a low-ball pitcher. I think that'd be easier on Scotty's shoulder, if he plays tomorrow versus today," Baker said. "We'll get him in there tomorrow. It's better for him and us to have another day."

Baker said shoulder soreness is not uncommon for Rolen, who has had several surgeries on his left shoulder.

"It's gonna be [sore]," Baker said. "It's gonna be probably until he retires."

Outfielder Jay Bruce also had a break Tuesday. Bruce and Rolen both represented the Reds at the All-Star Game, meaning they didn't get those days off like the rest of the team. Baker said he'd planned to rest both of them against the Pirates.

"I would have given them the day off when we came right back [from the All-Star break], except we were playing the Cardinals," Baker said.

Arredondo on track to return Friday

PITTSBURGH -- Right-hander Jose Arredondo should be ready to come off the disabled list when he is eligible on Friday, Reds manager Dusty Baker said before Tuesday's game against the Pirates.

Arredondo was placed on the 15-day disabled list on July 15 with a strained right forearm. The move was retroactive to July 7, though, because Arredondo's last appearance was on July 6. He threw a bullpen session Tuesday, and Baker said he would be evaluated Thursday.

"He's getting close," Baker said. "He was close when we put him on the DL. We just couldn't afford to go backwards and not have him available."

Left-hander Jeremy Horst was called up from Triple-A Louisville when Arredondo was placed on the disabled list. He made his first appearance on Monday against the Pirates, allowing one hit and no runs in two-thirds of an inning.

Arredondo is 1-3 with a 3.04 ERA in 24 games this season, covering 23 2/3 innings. He began the season on the DL while recovering from surgery on his right shoulder, and returned on May 14.

Worth noting

• Daniel Tuttle, a right-hander in the Reds' Arizona League, received a 50-game suspension Tuesday after a second violation of the Minor League Drug Prevention and Treatment Program.

Tuttle was drafted by the Reds in the fifth round of the 2009 First-Year Player Draft. Between the Arizona League and Class A Dayton this season, Tuttle has compiled a 7-4 record with a 4.59 ERA in 16 games.

• The Reds (47-49) have fallen two games below .500 four times, beginning with a July 8 loss to Milwaukee that dropped them to 44-46. Cincy bounced back to win the following game each of the first three times.

• Entering Tuesday, the Reds were 1-6 against the Pirates in 2011. Their only win was an 11-2 victory on April 16. In that game, Mike Leake faced James McDonald -- the same pair who squared off Tuesday at PNC Park.
