After the Giants took a 1-0 lead in the seventh inning on a Buster Posey home run, the Nationals answered back in the bottom of the inning off right-hander Jake Peavy. After Bryce Harper drew a walk, Robinson came to the plate and hit a two-run homer to give the Nationals the lead.
Robinson's best moment may have come a few minutes later when Nats fans asked for a curtain call, the first of his Major League career.
"That was about a big a shot of adrenaline that you could possibly ask for," Robinson said.
