Lafayette Christian Academy rode the proven scoring duo of Jacob and Kaleb Ledoux to a 64-55 win against Comeaux on Saturday night, vaulting the Knights into a semifinal matchup against St. Augustine.

The twins combined for 31 points, pouring in 15 from 3-point territory.

“They’re growing. It’s been a lot of work over the summer and early in this year,” said Lafayette Christian coach Byron Stark. “But they’ve done a good job in accepting some of their leadership roles. We’ve done a lot of things in our practices and workouts that give them that responsibility.”

Freshman guard Greg Williams contributed 15 points, 11 in the first half, helping give the Knights a comfortable 13-point lead at halftime.

Williams is the No. 4 small forward in the nation, according to high school recruiting service future150.com.

Williams was also the Knights leading rebounder with eight.

After struggling in the first game, Williams bounced back from what Stark dubbed the “human effect.”

“I always have to tell people he’s only a freshman,” Stark said. “Through the course of 30 games you’re going to have some poor ones.”

The Spartans tried to work their way back into the game on defense, utilizing a full-court press for most of the second half. But Williams used some slick ballhandling on several occasions to split the defense and finish at the rim.

Lafayette Christian shot a combined 80 percent (16-of-20) from the free-throw line.

Williams and the Ledoux twins used a combination of long-range accuracy and the ability to finish at the rim to beat the Spartans defense.

The three combined to score 46 of the Knights’ points.

The inexperienced Spartans ballhandlers could not contend with the Knights half-court trapping defense, committing several turnovers.

A strong shooting start by senior Jaleel Moore helped keep the Spartans in the game in the first quarter, but the shots stopped dropping as the defensive pressure ramped up.

Moore finished with 13 points on 6-for-18 shooting, including shooting 11 percent from 3-point territory.

The Knights limited Comeaux to one shot per possession most of the time and held a six-rebound edge over the Spartans.

Comeaux will play Ellender in the fifth-place game at 3:30 p.m. Sunday.
