"I feel good," Susac said before the game. "I feel I made big strides in my last couple games, just timing-wise taking better swings."
Susac's presence gives manager Bruce Bochy the option of playing Buster Posey more at first base, in an effort to save the slugger's legs. Posey started 79 of the Giants' first 117 games behind the plate, but he has caught 21 of the 26 games since Susac went down.
The biggest obstacle for Susac was getting his timing back at the plate.
"Especially with the hand, you can't really do any real strength exercises either so that's been the grind the past week just building back the strength and getting used to swinging the bat again," Susac said.
