South went just 6-of-32 from the floor and was outscored 31-15 in the second half as the Trailblazers picked up a key Big 9 Conference victory.
The Rebels bounced back from a 1-for-12 shooting effort in the first quarter and trailed by two points at the break.
They went on to grab a 25-24 lead when Tyler Ashworth completed a three-point play with 4:02 left in the third period, but Boone put together a 27-5 run that spanned the next 12:48.
By that time, the Trailblazers had a 51-30 lead and their starters were giving way to the reserves, who played the final 1:14. South shot just 25 percent for the game and struggled to make anything good happen on either side of the court.
“We shot poorly, which that’s going to happen once and a while, but defensively, we just didn’t show up,” South coach Mark Pendleton said. “The effort defensively just wasn’t there.”
The lone bright spot for the Rebels was the second quarter, when they got the ball inside to Ashworth, Logan Blair and Dustin Sims, who combined to score all 17 of South’s points in the second period.
While the Rebels struggled, the Trailblazers ripped off a 15-3 run and followed it up with the 12-0 burst that put the game away.
Cody Connell came on strong for Boone during the decisive second half, scoring 10 of his 12 points after intermission.
Boone coach Ryan Arnold said his team gave up too many offensive rebounds and too many shot attempts. But after losing six games in overtime this season, three of them in league play, Arnold was more than happy to walk away with the victory.
“I hope our defense had a little to do with that,” Arnold said of South’s low shooting percentage. “Maybe we caught them on an off night, but in this league a win’s a win and you take them any way you can get them.”
Ashworth and Sims scored 10 points each to pace the Rebels (11-10, 3-6) while Nick Jones scored 18 to lead the Trailblazers (9-11, 3-7).
In the girls’ varsity contest, the Lady Rebels used a 12-0 run in the second quarter to build a commanding lead and won 48-39 over the Lady Trailblazers.
Last time these two teams met, Boone (5-16, 2-8) kept the Lady Rebels (5-12, 2-7) from getting the ball inside and came away with a win. But on Tuesday, South got 12 points each from Makensey Campbell and 10 from Lauren Latture.
“They got it where they wanted it this time,” Boone coach Tim Campbell said. “Last time we defended the post better — this time they destroyed us in the post.”
Jessie Summie scored nine points to lead Boone.
For South, the game plan was simple but effective.
“We wanted to pound it inside on offense and pressure them on defense,” South coach Josh Tate said. “We played pretty hard for the most part.”
