Alex Crockett crossed twice and Bristol conceded two tries - one a penalty and the other a Daniel Browne touchdown, while Haydn Thomas was in the sin-bin.
It was Manning who would own this night, though, finishing 30 of 40 for 296 yards, a touchdown and one tremendous 38-yard pass to Mario Manningham, with 3:46 left on the clock and the Giants down 17-15.
