Lincoln County (8-3) led the game from start to finish and held a 26-16 advantage at halftime before outscoring MCHS 17-13 over the final two quarters to claim the 14-point victory.
Marshall County struggled offensively the entire contest and mustered just 11 field goals on 28 percent shooting, which included a 2-of-9 effort from three-point range, while hitting only 5-of-12 foul shots.
The Tigerettes did outrebound the Lady Falcons 31-24 and held a 12-10 edge on the offensive glass, but had trouble handling Lincoln County's full court press and committed 26 turnovers.
Although the Lady Falcons shot just 30 percent (12-of-40) and hit only 2-of-14 attempts from beyond the arc, Lincoln County knocked down 17-of-24 free throws and finished with 15 turnovers.
"Turnovers have been our Achilles heel all season," said MCHS coach David Junkins. "We've gotten better defensively as the season's gone along and I'm pleased with that, but it's difficult to win when you have nearly 30 turnovers every game. We need to value the basketball more and we have the talent and ability to do it."
Forward Jameka Braden led the Tigerettes with 10 points, 10 rebounds, and two blocked shots, while Mecia Reed and Morgan Moyers tallied seven and three points respectively. Marissa Lyttle, Michala Hopkins, Megan Sanders, and Kemesha McFall also chipped in two points apiece for Marshall County, and Joslyn Scarfone had one point.
Shooting guard Mykyla Ashby paced the Lady Falcons with 15 points and three steals, while Hannah Barnes added 11 points. Khaila King and Cortney Storey notched eight and four points respectively for Lincoln County as well.
MCHS dug themselves an early hole, as the Lady Falcons flew out to a 19-7 lead with 5:14 left in the second quarter on the strength of nine points from Ashby and six points from Barnes.
The Tigerettes put together a 9-4 run with the help of five points from Reed to narrow the gap to 23-16 late in the second quarter, but Barnes nailed a trey from the right corner in the waning moments of the stanza to give Lincoln County a 26-16 advantage at the break.
After Moyers buried a three at the start of the third to trim the deficit to 26-19, the Lady Falcons outscored Marshall County 7-2 the rest of the period thanks to a short bank shot by King and five free throws to stretch their lead to 33-21.
Reed hit a pull up jumper early in the fourth quarter to make it 33-23, but Lincoln County responded with a 6-0 spurt behind four points from King to forge a 39-23 advantage with 3:36 left before cruising to the 43-29 victory
