First-time starter Craig Breslow and six relievers combined on a five-hitter and the Boston Red Sox beat Baltimore 8-0 Saturday, further denting the Orioles' slim playoff hopes.
A day after Boston journeyman Rich Hill blanked Baltimore on a two-hitter, the Red Sox emptied their bullpen.
The Orioles fell 4 1/2 games behind Houston for the AL's second wild-card spot. Third baseman Manny Machado made a pair of two-run errors, both coming on grounders by Xander Bogaerts.
Making his first career start after 522 relief appearances over 10 years, Breslow allowed two hits in four innings. Heath Hembree (2-0) worked one inning for the win.
Wei-Yin Chen (10-8) took the loss.
