After Huntington jumped out to a 17-10 lead after the first quarter, Hurricane rallied to take a third-quarter lead that reached as many as five and held a two-point advantage heading into the final period.
"That was our game plan going in, make it as ugly as possible," Sutherland said.
"We told our guards, 'We're going to have to crash down [for rebounds].' To some extent we did but not well enough and early it ate us up. The first half is what killed us.
"We played hard but it just didn't go in. The last two games we shot almost 60 percent from the floor and then tonight most of the shots were 2 feet from the basket and they just wouldn't go in. There's not much you can do about that."
J.R. Howard came off the bench and had seven of his nine points in the fourth quarter, including a basket to put Huntington up 41-39, accounting for the Highlandes' first lead since 24-23 at the beginning of the third quarter.
Dunn-Martin finished with 17 points, five rebounds and three assists for Huntington.
Trey Dawson led Hurricane with 17 points, including all three of the Redskins' 3-pointers.
His final long ball pulled the Redskins within 48-46 with 37.6 seconds left. Hurricane got the ball back but Jacob Lemmerman's shot was blocked in the lane, setting up Dunn-Martin's final free throws.
Henry Sorsaia added 14 points for the Redskins.
