The Tigerettes (8-13), meanwhile, had their modest two-game winning streak snapped earlier in the evening when they were thumped 67-19 by a strong Lady Lion squad.
Having defeated Columbia 61-52 in their previous meeting on Nov. 19, the Tigers took charge early in Monday's contest and jumped out to a 14-8 lead in the first quarter behind six points from Chris Walker.
After pushing their lead to 30-19 at the end of the second period with the help of six points from Malek Sain and four points from Cameron Bowers, the Lions narrowed the gap to 42-35 in the third period thanks to seven points apiece from Kevonta Cathey and Dre Hall.
Marshall County, though, weathered Columbia's rally attempt and outscored the Lions 15-14 in the fourth quarter on the strength of four points apiece from Bowers and Barry Mayes to claim the eight point-victory.
With Monday's triumph, the Tigers have now defeated Columbia in six of the last seven meetings between the two teams.
Bowers led Marshall County with 17 points and Walker followed with 11 points. Kevin Peterson, Aaron Hobbs, and Malek Sain also tallied eight, seven, and six points respectively, while Mayes and Kasey Pleas chipped in four points apiece.
"It was a nice win. We got up on them early and defended well. We're starting to jell and I think we're headed in the right direction, but hopefully we haven't peaked because I know we have some better basketball in us," said MCHS coach Adrian Wilson. "Cameron Bowers was excellent in all facets of his game and Chris Walker played one of his best games of the season."
Cathey paced the Lions with 15 points and Hall notched 13 points. Khalil Counts and Tremell Buchanan tallied seven and five points for Columbia as well.
In the opening game of the night, things got ugly for the Tigerettes early, as the Lady Lions (21-3) raced out to a 24-5 lead in the first quarter behind nine points from Makayla Timmons and six points from Aryanna Gilbert before outscoring MCHS 16-6 in the second period to take a 40-11 advantage into the break.
After putting together a 18-3 run in the third quarter to forge a 58-14 lead, Columbia outscored the Tigerettes 9-5 in the fourth period to coast to their sixth straight win over Marshall County.
Aryanna Gilbert led three Lady Lion players in double figures with 15 points, while Makayla Timmons and Cokie Young notched 13 and 12 points respectively. Kanytra Bumpas also added eight points for Columbia and Keiana Gilbert chipped in six points.
Kiya Morris paced the Tigerettes with seven points, while Allison Hargrove and Allison Hargrove both had three points apiece. Megan Sanders, Marissa Lyttle, and Kemesha McFall rounded out the scoring for Marshall County with two points each.
