Jones had 25 points and 15 rebounds for his sixth double-double this season. Bryant was 4-for-12 from the floor on the way to 15 points. Deniz Kilcli had his 10th straight game in double figures with 12 points, but he was just 5-for-11. He shot 50 percent or better in the previous six games
The only other player who had more than one basket was Williamson, who didn't play in the second half until 1:35 remained.
"I'm fine with it," Williamson said. "We made a great run and we got the lead and we won the game."
WVU shot 50 percent in the second half and 45.5 percent for the game with 5-for-16 shooting from 3-point range. The Mountaineers were outrebounded in the first half, outscored in the paint and on second-chance points and missed 16 of 27 shots, which forced Huggins to move around his lineup and give players like Williamson an early look.
Williamson usually plays late when the outcome is no longer in question and the fans are chanting his name.
"It's really not different in my mind," he said. "Whenever Coach Huggins puts you in, you've got to go out there and play hard, you've got to play defense and you've got to get to the ball. Those are the three things you have to do whether you go in at the end of the game or the beginning of the game."
The Mountaineers completed the preliminary games in the Las Vegas Classic after beating Texas A&M-Corpus Christi 84-64 Saturday. They travel Wednesday to Las Vegas, where they'll play Missouri State Thursday as Huggins takes his first crack at his 700th career victory and then No. 6 Baylor Friday.
Tennessee Tech (6-5) shot just 33.9 percent (19-for-56) and tried to make only half as many 3s as Williamson. Guard Jud Dillard had 15 points and 12 rebounds and Zach Bailey added 10 points off the bench.
Leading scorer Kevin Murphy had seven points on 2-for-11 shooting. He was averaging 21 points per game, but had a hard time against Bryant's defense.
"Truck did a terrific job," Huggins said. "I think after three or four possessions, he said, 'I've got him.' I thought Truck could guard him, but he did a great job. He's grown up a lot. Defense to Truck was like a bad word when he got here, but he's progressed so far and he understands we need him to guard."
