DENVER (AP) - Carlos Correa hit one of Houston's four home runs, Brett Olberholtzer pitched effectively into the seventh inning and the Astros continued their power surge Wednesday night in an 8-4 win over the Colorado Rockies.
Chris Carter, Preston Tucker and Jake Marisnick also homered for the first-place Astros, who have won four straight and lead the majors with 95 home runs. Correa and George Springer had three hits each.
Olberholtzer (2-1) followed up his eight shutout innings against Seattle on Friday with another strong outing. He allowed three runs and eight hits, struck out five and didn't walk a batter in 6 1-3 innings.
He worked around Charlie Blackmon's leadoff double in the sixth but left after allowing Nick Hundley's RBI single in the seventh.
