BALTIMORE (AP) -- Chris Davis hit his major league-leading 38th home run, a two-run shot in the sixth inning that gave the Baltimore Orioles their first lead in a 4-3 victory over the Houston Astros on Tuesday night.
Davis had gone 10 straight games without a long ball until connecting off Lucas Harrell (5-11).
J.J. Hardy hit a two-run single in the fourth inning to start Baltimore's comeback from a three-run deficit. The Orioles got only three hits in winning for the second time in seven games.
Wei-Yin Chen (6-3) allowed three runs, seven hits and a walk in 7 1-3 innings for his fourth straight win. The left-hander had a season-high nine strikeouts.
Jim Johnson worked a perfect ninth for his 36th save.
