– Domingo Santana couldn’t even feel his feet touch the dirt as he ran around the bases following his first big league homer.

Another clutch hit from a recent call-up. The pipeline of promising prospects just doesn’t seem to end for the Houston Astros.

Rookie Preston Tucker homered and drove in three runs, Santana came through in a pinch-hitting role in the eighth and the Astros beat the Colorado Rockies 8-4 Thursday for their fifth consecutive win and AL-high 40th of the season.

“We need plenty more. It’s a long season,” Astros coach A.J. Hinch said.

Santana was recalled from Triple-A Fresno this week when Colby Rasmus went on the bereavement list following the death of his grandmother. Santana lined a hanging slider from Scott Oberg into the bullpen for a three-run homer, giving the Astros an 8-3 lead.

“It was emotional,” Santana said of his first homer in the majors. “Pretty excited.”

Houston leadoff hitter George Springer extended his hitting streak to 11 games as the Astros swept the four-game, home-and-home series with the Rockies. Hitting behind Springer, Carlos Correa stole three bases and then, in the No. 3 hole, Tucker hit a homer in the first and a double in the fifth that scored the go-ahead run.

Cleanup hitter Chris Carter also drove in two runs as Houston improved to 8-1 in interleague play this season after going 5-15 a year ago.

“It never ceases to amaze me with this team,” Hinch said. “Different contributions all the way through.”

Collin McHugh, who turns 28 on today, got the win after allowing three runs on four hits in six innings.
