The Orioles have placed 27-year old righty reliever Pedro Strop on the 15-day disabled list, retroactive to May 24th, due to a strained lower back. Strop has pitched in 22 games (0 starts) for the Orioles so far this year and he is 0-2 with a 6.11 ERA and a 1.59 WHIP. The Orioles have called up 25-year old righty Steve Johnson to replace Strop in the pen. He pitched in 1 game (1 start) earlier this year for the Orioles and he was 0-1 with a 13.50 ERA and a 2.75 WHIP. He also has pitched in 4 games (all starts) in AAA-ball so far this year and he is 1-2 with a 5.49 ERA and a 1.48 WHIP. Johnson will try to get back the magic he had working in 2012 for the Orioles this time around. Johnson pitched in 12 games (4 starts) for the Orioles last year and he was 4-0 with a 2.11 ERA and a 1.07 WHIP.
