CHICAGO (AP) - Madison Bumgarner allowed two runs while pitching into the seventh inning, Marco Scutaro had three hits and the San Francisco Giants held off the Chicago Cubs 3-2 on Saturday.
Pinch-hitter Dioner Navarro hit a two-out, two-run homer off Bumgarner in the seventh to pull the Cubs to 3-2.
It was Navarro's second career pinch home run in two days, each hit from a different side of the plate. His tying homer in the ninth Friday was hit from the left side.
The Cubs threatened in the eighth, putting two on with no outs, before Alfonso Soriano grounded out and Welington Castillo hit into a double play against Santiago Casilla, who earned his first save.
Giants closer Sergio Romo was unavailable after throwing four of the last five games.
Bumgarner (3-0) struck out six and walked two, one intentional, in 6 2-3 innings.
