BALTIMORE — 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 (Wednesday, Manila time).
Davis had gone 10 straight games without a long ball until connecting off Lucas Harrell (5-11). Earlier, Davis extended his run of games with a strikeout to 23, the longest streak in Orioles history.
The slumping slugger came in with a .205 batting average since the All-Star break and hadn't hit a home run since July 14. The drive off Harrell was his first extra-base hit in seven games.
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.
Darren O'Day got two outs in the eighth and Jim Johnson worked a perfect ninth for his 36th save.
Jonathan Villar stole home and Robbie Grossman had three hits for the Astros, who are 2-9 since the break.
Bud Norris was scratched as Houston's starting pitcher amid rumors he would be dealt before the non-waiver trade deadline of Wednesday at 4 p.m.
"You have a guy that has attracted a lot of interest from other ballclubs," manager Bo Porter said. "It just made more sense to not risk injury at this juncture of the conversation."
Making his first start since July 5, Harrell gave up only two hits but issued five walks — three of which turned into runs.
Chen retired the first seven batters he faced before running into trouble in the third. Three straight singles loaded the bases for Jose Altuve, who bounced a two-run single to left. With the bases full and two outs, Chen went to the stretch with his back toward Villar, who danced halfway down the baseline before breaking for home. He made it easily for a 3-0 lead.
Baltimore got two runs back in the fourth. After Harrell walked the bases loaded, Hardy got the Orioles' first hit, a two-run single up the middle.
After Nick Markakis drew a leadoff walk in the sixth, Davis hit an opposite-field drive to left.
