Steve Holm entered the game as a defensive replacement at catcher, then delivered the biggest hit of the day.
Holm hit a go-ahead, two-run drive in the seventh inning for his first major league home run, and the San Francisco Giants held on for a 4-3 victory in the rubber game against the Philadelphia Phillies on Sunday.
Holm homered in his first at-bat on the first pitch he saw from J.C. Romero (3-1) after replacing Bengie Molina in the top of the seventh, sending the ball into the seats in left-center.
