Caldwell County put up a fight, but Madisonville-North Hopkins did what the Maroons usually do in the fourth quarter.
A 3-pointer by Cayden Fraliex had the visiting Tigers within 51-46 with still 5:28 to play.
But Madisonville ran off 10 straight points as part of a 15-2 run to close the game, and finished off a perfect regular-season run through the 7th District with a 66-48 victory Friday night over the Tigers.
It was the 11th straight victory for the Maroons, who improved to 22-3 overall and 6-0 in the district. The defending 2nd Region champions will be the No. 1 seeds for the district tourney later this month.
Caldwell, now 9-14 and 2-2, led 6-0 early behind a pair of 3-pointers from Tripp Branch.

However, a stickback by K’suan Casey and then a 3-pointer by Marquise Parker just ahead of the horn sent Madisonville to the final stanza with a 47-39 advantage.
Five points was as close as Caldwell could get in the fourth quarter before the Maroons blew open the game over the final 5-plus minutes to win by 18 points.
