Kevin Jones led four Mountaineers in double figures and West Virginia defeated Marshall 78-62 on Wednesday night in the Chesapeake Energy Capital Classic at the Charleston Civic Center.
West Virginia has now won five of its last six games against Marshall, and leads the all-time series 29-11.
"It meant a lot to us, especially coming off the loss from last year," Jones said. "For us to be so young, I'm glad with how we kept our self poised."
The game was the 40th meeting between the two in-state rivals.
Jones led all scorers with 25 points.
Freshman guard Jabarie Hinds and senior guard Truck Bryant chipped in 22 and 10 points, respectively.
The Mountaineers outrebounded the Herd 36-26 and shot 49 percent from the field.
"We knew how good they were rebounding the ball," said West Virginia head coach Bob Huggins. "KJ (Kevin Jones) is going to get his (rebounds)."
How does Jones do it?
"No secret. Just good old-fashioned boxing out," Jones said. "We did a good job of boxing everybody out and securing the rebounds."
"I didn't do it alone. It was just a total team effort," he said.
Marshall held a 37-36 advantage early in the second half, but West Virginia outscored the Herd 42-26 the rest of the way.

The Mountaineers started to pull away midway through the second half.
Senior forward Kevin Jones hit a left-handed hook to give his team a 46-37 advantage with less than 12 minutes left to play.
"Once we got up to nine, we wanted to continue to run motion," Huggins said. "I wanted to run clock and take what was there."
Jones hit a three-pointer with six minutes left to play, and West Virginia had its largest lead of the game, 55-45.
"He had two huge threes," Huggins said.
