Edgar Renteria tied a career high with five hits and the San Francisco Giants broke away from the Houston Astros 10-4 Wednesday to complete a season-opening three-game sweep.
The Giants are 3-0 for the first time since 2003, when they began with a sweep at San Diego and won seven straight. Houston last started 0-3 in 2007.
It was 4-all when Juan Uribe doubled in the eighth inning and scored the go-ahead run when Sammy Gervacio (0-1) threw away a bunt. The Giants added another run in the inning, then scored four times in the ninth.
Aaron Rowand had four of the Giants' 19 hits. John Bowker had a two-run homer and Travis Ishikawa added his first career pinch-hit home run.
Jeremy Affeldt (1-0) got the win.
