CINCINNATI -- The Reds put right-handed reliever Jose Arredondo on the 15-day disabled list on Friday because of a stiff forearm, shuffling their bullpen before the start of their weekend series against the St. Louis Cardinals.
Arredondo missed last season following reconstructive elbow surgery. He made 24 appearances for Cincinnati this season, going 1-3 with a 3.04 earned run average. His right forearm began bothering him before the All-Star break, and tests detected a strain.
Reds manager Dusty Baker said Arredondo's injury isn't related to his elbow surgery. It began bothering him during a series in Milwaukee last weekend, leaving him unavailable to pitch.
"He's been kind of available/unavailable for a while," Baker said. "He wasn't available in Milwaukee. When a guy's had Tommy John [surgery], you want to be careful, even though it's not in the same area. He just didn't feel 100 percent.
"Even though he says he's fine today, we can't afford to be short tomorrow or the next day if he doesn't feel right. We need him available on an everyday basis."
The defending NL Central champions resumed play Friday in fourth place, four games behind Milwaukee and St. Louis.
Left-hander Jeremy Horst was recalled from Triple-A Louisville to take Arredondo's spot. It's his second stint with Cincinnati. Horst made five appearances between May 28 and June 22, giving up nine hits and three earned runs in 8 1/3 innings.
