Scott Feldman and three Houston relievers limited the Orioles to five hits, and the Astros defeated Baltimore, 4-1, Tuesday at Camden Yards.
Feldman (4-4) gave up a run on four hits in six innings of work, striking out two and walking three. Luke Gregorson pitched a perfect ninth, striking out two, to record his 13th save.
Chris Tillman (2-6) took the loss, giving up two runs on five hits in seven innings, striking out five and walking three.
The O’s led 1-0 on a sixth-inning sacrifice fly by Chris Davis. Houston took the lead for good in the seventh, tying the game on an RBI single by Chris Carter, and taking the lead on a run-scoring double by Jason Castro.
A two-run single by Luis Valbuena in the eighth provided insurance for the Astros.
