Brayan Villarreal walked Marco Scutaro with the bases loaded and two outs in the bottom of the ninth, handing the San Francisco Giants a 3-2 victory over the Boston Red Sox on Tuesday night.
Roger Kieschnick started the winning rally with a one-out single off Franklin Morales (2-1). The Giants loaded the bases with two outs when Morales walked Andres Torres and hit pinch-hitter Hector Sanchez with a pitch on the left wrist.
Villarreal then threw four straight balls to Scutaro in his first appearance with the Red Sox, giving the defending World Series champions a rare reason to celebrate this summer.
Sergio Romo (4-6) pitched a perfect ninth for the win.
