The Orioles have announced that they’ve placed righty Darren O’Day on the 15-day DL (retroactive to August 12) with a right shoulder rotator cuff strain. To take his place on the active roster, they’ve recalled righty Tyler Wilson from Triple-A Norfolk. The seriousness of the injury isn’t yet known.
O’Day has been one of the AL’s best relievers in each of the past several seasons, but he hasn’t quite been up to his usual standards this year — he’s issued 4.3 walks per nine innings, more than doubling his 2015 walk rate and contributing to a jump in his ERA from 1.52 to 3.95. He’s also pitched just 27 1/3 innings, missing most of June and July to a hamstring strain. Nonetheless, he’s maintained a very respectable 10.9 K/9.
The 26-year-old Wilson has pitched 85 innings for the Orioles this season, most of them as a starter, posting a 4.98 ERA, 4.9 K/9 and 2.2 BB/9. The O’s optioned him to the minors last week. There’s been no official word from the Orioles, but it appears they’ll use him as a reliever this time, since the rotation has been healthy and effective lately.
