ST. LOUIS (AP) George Springer hit a go-ahead two-run homer in the eighth inning and the Houston Astros completed a two-game sweep of the St. Louis Cardinals with a 4-1 victory on Wednesday night.

Tony Sipp (1-2) got the last out of the seventh in relief of Collin McHugh, Carlos Correa's two-run single off Trevor Rosenthal made it a three-run lead in the ninth and Will Harris finished for his fifth save in as many chances.

The Astros are 15-7 since moving Springer to the leadoff spot ahead of Jose Altuve. But he had been in a 4-for-37 slump before connecting to straightaway center off Kevin Siegrist (4-2) with two outs for his 15th homer.
