Brandon Crawford, Brandon Belt and Austin Slater homered and the San Francisco Giants kept rolling at home, beating the San Diego Padres 7-1 Saturday. Kevin Gausman (3-0) permitted three hits and struck out seven in six smooth innings before San Francisco's bullpen blanked the Padres for the final three innings. Lightly regarded when the season began, the Giants (20-13) own the National League's best record and a 2 1/2-game lead over second-place San Diego in the West.
