The Orioles purchased the contract of left-handed reliever Clay Rapada today and placed righty Chris Jakubauskas on the 15-day disabled list, retroactive to Sunday, with a strained right groin.
To make room for Rapada on the 40-man roster, the Orioles moved righty Justin Duchscherer (left hip, back issues) from the 15-day to the 60-day disabled list. That means he won't be eligible to pitch in the big leagues until the end of May, which seems logical since he has faced big league hitters once (two innings in a March exhibition game) this calendar year and will need time to get ready once he is relatively pain-free.
Rapada, 30, is 3-0 with a 4.22 ERA in 46 major league games that span parts of four seasons. Last year, Rapada pitched in 13 games with the Texas Rangers, compiling no record and a 4.00 ERA in nine innings.
He allowed one hit and one walk while striking out three and picking up a save in two scoreless innings for Triple-A Norfolk this season.
The sidearmer is considered a lefty specialist, and in his big league career, left-handers have hit just .186 off of him (with a .305 on-base percentage) in 83 plate appearances. In comparison, right-handers have hit .292 (with a .418 on-base percentage) in 79 plate appearances. He allowed just one hit and two walks while facing 21 lefties last year for the Rangers.
Jakubauskas, 32, allowed six runs in 7 1/3 innings in three games with the Orioles this month. On April 19, he made his first big league appearance since April 24, 2010, when he was struck in the head with a line drive in his only game with the Pittsburgh Pirates.
