Orioles place left-hander Wei-Yin Chen on 15-day disabled list

The Orioles today announced that they have placed left-hander Wei-Yin Chen on the 15-day disabled list, retroactive to May 13, with a right oblique strain. The club has also recalled right-hander Alex Burnett and infielder Yamaico Navarro from Triple-A Norfolk.

Chen was injured during his Sunday start at Minnesota in which he picked up his third win of the year with five scoreless innings. Chen is 3-3 with a 3.04 ERA (47.1IP,16ER) in eight starts for the Orioles. Chen led the Orioles with 32 starts in 2012.

Burnett, 25, joins the Orioles for the third time this year (also April 22-24 and May 9-10). He appeared in one game, allowing one hit and striking out one in a scoreless inning May 9 against Kansas City. In seven games with Triple-A Norfolk, Burnett was 1-0 with a 1.86 ERA (9.2IP, 2ER) and eight strikeouts.

Navarro, 25, returns for a second stint with the Orioles as he was with the club April 5-6 but did not see game action. In 34 games with Norfolk, Navarro was batting .303 (37-122) with two homers and 13 RBI. He scored 28 runs in those 34 games and posted a .395 on-base percentage for the Tides.
