Senior guard Brandon Burgraff, who is from Matewan, began the rally with a 3-pointer, then junior guard Jaren Marino, a former South Charleston High School player, added a layup as Tech took the lead for good at 86-85.
Burgraff paced the Golden Bears with 26 points, including a 6-of-10 performance on 3s, and Marino added 17 points on 5-of-11 shooting and six rebounds. Tech senior forward Armond Perez pitched in 15 points on 6-of-9 accuracy with seven boards.
"We forced some big turnovers down the stretch,'' said Williams. "We were fortunate we made some big plays.
"[Salem] can turn games around with their pace. Their zone is hard to deal with. They do a good job with changing defenses. They don't do the same thing all the time, then they change up out of timeouts.''
Brock finished with a team-high 31 points for Salem, which counted Tuesday's game as an exhibition. The Tigers shot just a little under 50 percent and forced Tech into 20 turnovers.
"We made a lot of bad mistakes,'' Williams said. "Our defense was horrible. I thought their big guys outplayed our big guys. You've got to come to play.
"The competition is going to get better and better. These guys are really good kids. They have high character so they keep battling and play hard all the time. The want to be good.''
