Jackson and Jameel Warney each finished with 11 points for the Seawolves (17-5, 8-1 America East Conference), who have won nine of their last 10 games. It's also Stony Brook's 10th road victory of the season.
Stony Brook led the majority of the second half, but had a tough time holding off New Hampshire. The Wildcats cut the lead to 53-52 on Chris Matagrano's free throw with 1:33 left in the game.
But New Hampshire pulled no closer as Jackson knocked down a 3-pointer with 1:16 remaining to give the Seawolves enough cushion for the victory.
