Derek Norris hit a three-run shot with two outs in the ninth inning for his first major league home run, and the Oakland Athletics walked off with a stunning 4-2 victory over the San Francisco Giants on Sunday.
Norris hammered a full-count pitch from Santiago Casilla (1-3) over the left-field wall to help the A's avoid the first three-game sweep by San Francisco in Oakland. A's players streamed out of the dugout in those bright gold uniforms and mobbed Norris at home plate.
It was Casilla's second blown save in 22 chances this season in place of bearded closer Brian Wilson. The ending also washed away San Francisco starter Matt Cain's bid for a ninth straight win.
Jim Miller (2-0) pitched 1 1-3 scoreless innings for the victory.
Buster Posey's two-run homer in the first was all the Giants could squeeze out against A.J. Griffin, who retired 16 of the next 18 batters he faced in his major league debut. Griffin gave up three hits, one walk and struck out four in six-plus innings.
