After building a 16-11 lead in the first half, the Tigerettes (4-3) opened up a 28-18 advantage early in the fourth quarter before staving off a late E.A. Cox rally.
Although LMS hit just 6-of-13 free throws and shot only 26 percent from the field overall, Lewisburg outrebounded E.A. Cox 30-18 and held a 15-2 edge on the offensive glass.
"I thought we played hard, but we couldn't get a shot to drop. All in all it was a good win, but we didn't play our best," said LMS coach Chris Coleman. "We did a great job on the boards and rebounded very well. Without that we probably wouldn't have gotten up on them like we did. It was the most positive aspect of our game tonight."
Point guard Makiya Morris led the Tigerettes with 14 points, eight rebounds, and three steals, while center Alexis Ford tallied six points and seven rebounds. Zachuriya O'Neal and Alexia Allen also chipped in four and three points respectively, and Karlasia Williams and Taiandra Hutton both had two points.
The Lady Cougars, conversely, shot 37 percent from the floor (10-of-27), but made just 6-of-19 free throws and committed 22 turnovers.
Taliyah Lashley-Jones and Kyjia Pillow both scored seven points to pace E.A. Cox, while Brooklyn Prewett and Brittany Webster added four points apiece.
Lewisburg trailed 2-0 late in the first quarter before rattling off seven straight points thanks to a pair of jumpers from Morris and an Allen trey to pull ahead 7-2 early in the second period.
LMS then created some more breathing room by outscoring E.A. Cox12-7 through the first 7:33 of the second half on the strength of four points apiece from O'Neal and Morris to push their lead to 28-18 early in the fourth quarter.
The Lady Cougars scored six straight points to trim the deficit to 30-24 with 1:06 left, but Ford scored on a layup and Morris hit one-of-two free throws to help seal Lewisburg's 31-26 victory.
