Walpole was backed against a wall entering the fourth quarter Saturday at Wellesley.
The 12th-ranked Rebels (3-1) trailed, 28-27, when they reeled off 22 points in the fourth, thanks to two touchdown passes by Will Bolster to propel Walpole to a 49-35 win.
Bolster found Jack Lavenchy for a 27-yard score on the first play of the fourth to put the Rebels up, 35-28.
Bolster then found Colton Mitchell for a 22-yard score and Steve Cuqua added insurance on an 11-yard touchdown to build a 49-28 lead with 3:19 to go.
The Raiders (1-3) didn’t go away easily. Myles Coles hauled in a 62-yard touchdown from John Fadule to cut the deficit to 14. Wellesley recovered the ensuing onside kick to make it a one-possession game.
But Myles Cofield ended the heroics when he picked off a pass to secure the win.
Bolster finished 15 for 20 for 260 yards and three touchdowns.
Fadule scored on a 1-yard keeper to give the Raiders a 1-point lead entering the fourth. Wellesley led, 21-13, at the half until Bolster hit Cuqua on a 65-yard strike, then found Joe Rockwood for the 2-point conversion to tie the game.
Walpole retook the lead later in the third when Bolster darted 38 yards to make it 27-21.
