Nolan Reimold doubled, tripled and drove in three for the Orioles, who won their fifth consecutive game after plating nine runs against New York starter A.J. Burnett.
Tommy Hunter (3-2) allowed four runs in seven innings to help Baltimore win on a night the team honored the late Mike Flanagan.
Flanagan, who died Wednesday of a self-inflicted gunshot wound to the head, won the 1979 Cy Young as a pitcher for the Orioles and helped the team win the World Series in 1983. He then served as a coach, front office executive and broadcaster for the team.
Burnett (9-11) matched a career high with nine runs allowed in five innings, finishing an arduous August. In five starts, he posted an 11.91 ERA (30 earned runs in 22 2/3 innings), and allowed six homers and 44 hits.
The right-hander has given up at least seven runs in four outings this season -- three of which came in August.
