Roger Clemens struck out a season-high 10 batters in his 331st career win, pitching Houston past the San Francisco Giants 4-1 Saturday night. Lance Berkman hit his first home run of the season after a two-run shot by Craig Biggio in the sixth inning, helping the Astros end a four-game losing streak with their second victory in 12 games. ``They went out and did it. It just shows their persistence,'' Clemens said. ``He had another good night, another fantastic night,'' Houston manager Phil Garner said. ``When Biggio hit that home run and Berkman hit his, there was a big sigh of relief. We all felt it on the bench.''
