BALTIMORE -- Japanese pitcher Koji Uehara was placed on the 15-day disabled list Wednesday by the Baltimore Orioles, who hope the extended break will enable the right-hander to bounce back from a nagging hamstring injury.
The move coincides with the return of designated hitter Luke Scott, who was activated from the DL after missing 16 days with a strained left shoulder.
Uehara strained his left hamstring during a start Saturday against the Washington Nationals. It's the same hamstring that bothered him for years while he pitched in Japan, and it also sidelined the 34-year-old rookie in March during his first spring training with Baltimore.
"I've had a long relationship [with the hamstring] for 10 years, so it's always there," Uehara said through an interpreter.
The Orioles hope Uehara's latest run-in with the hamstring will soon be over.
"It's something that we need to manage, something we need to get better so he can pitch deep into the season," manager Dave Trembley said.
Uehara, Baltimore's first Japanese-born player, is 2-3 with a 4.09 ERA in nine starts.
Uehara was scheduled to start Thursday against the Detroit Tigers. Instead, the Orioles are expected to recall right-hander David Hernandez from Triple-A Norfolk. It will be the major league debut for Hernandez, 3-1 with a 2.91 ERA for the Tides.
Scott hurt his shoulder while diving back to first base in a game against New York on May 10. He went 3 for 4 with a home run during a two-game rehabilitation assignment with Class A Delmarva.
"It's just a matter of getting my timing back, getting my swing back a little bit," Scott said. "But I feel good, and I'm glad to be back."
Scott was batting .303 with five homers and 15 RBIs before going on the DL.
