SAN FRANCISCO -- Matt Duffy was busy doing math in his head.
It was the bottom of the ninth inning in Sunday's series finale against Miami, and Giants catcher Andrew Susac had just hit a one-out single. So Duffy started started counting and found out he was five batters away from reaching the plate.
"I knew if I did come up, it would be bases loaded, two outs in a tie game," Duffy said.
The Giants shortstop was right. And he delivered.
Duffy came through with an RBI single to left field to give the Giants a 3-2 win and collect his first career walk-off hit.
