CINCINNATI -- The Los Angeles Dodgers put right-hander Brad Penny on the 15-day disabled list Tuesday with a sore shoulder that has bothered him for much of the season, then sent right-hander Hiroki Kuroda back to Los Angeles to have a sore shoulder examined.
He went back to Los Angeles for a medical test Monday that determined he has tendinitis. He was 0-7 in his last eight starts, and pitched only 3 2/3 innings in a 12-7 loss to Detroit on Saturday. He is 5-9 with a 5.88 ERA this season.
Penny has been taking pain medication before his starts because of the shoulder. The former All-Star said his shoulder bothered him while he was warming up during the weekend.
Manager Joe Torre said Penny could resume throwing later this week and might be able to return in two weeks.
"It's structurally fine," Torre said of Penny's shoulder. "They think what's tricked us all is when you look up there and see his velocity numbers seem to be pretty consistent, and at times he looked really good. But again, inconsistency probably matches up with the fact that he's had this discomfort. Some days have been better than others."
Left-hander Eric Stults was called up from Triple-A Las Vegas to take his spot in the rotation. He was 5-6 with a 3.59 ERA in 14 starts for Las Vegas.
Stults had three stints with the Dodgers last season, going 1-4 with a 5.82 ERA in five starts and seven relief appearances.
"The fact that he has some big league experience means he won't be a duck out of water," Torre said.
Kuroda was scheduled to start Wednesday's game against the Cincinnati Reds. Kuroda, who is 3-6 with a 4.04 ERA, told the team that his pitching shoulder has been bothering him at times. The team got him on a flight back to Los Angeles on Tuesday night to have it checked.
"I guess he's experienced this on and off for a while," Torre said. "He was ready to pitch tomorrow, but we decided to send him home and figure by the time we get home, we'll have an idea [what's wrong]."
Derek Lowe will move up a day and start Wednesday's game, with Stults finishing the series on Thursday.
