Belleville East did its part Tuesday night, but it received no cooperation from the Edwardsville Tigers.
East got 19 points from senior Darreon Reddick and 13 points from senior Cameron Hunter as it defeated host Collinsville 60-56 in a Southwestern Conference game.
The Lancers, who won the outright conference championship last season, entered the contest two games behind Edwardsville in the league standings. The Tigers, however, defeated host O'Fallon 54-46 Tuesday to nail down the outright title. Both squads have one regular-season game remaining.
The Lancers (19-8 overall, 9-4 SWC) led 24-23 at halftime and seemed to be in good shape with a 57-50 lead in the final two minutes. But a late run by the Kahoks (12-15, 4-9) drew them within 59-56 in the final seconds.
East clinched the outcome with a free throw.
Junior Brett Langley led Collinsville with 16 points. Emondre Rickman, a 6-foot-8 junior, finished with 13 points.
Alton 63, Belleville West 50
The host Redbirds led 20-4 after one quarter and were never headed in their victory over West.
The Maroons climbed within 32-26 early in the third quarter, but Alton answered with a 12-1 run that settled the matter.
The Redbirds improved to 21-5 overall and 9-4 in the SWC. The Maroons tumbled to 5-19 and 2-11. West shot 47 percent (18-for-38), but committed 25 turnovers, including nine in the first quarter.
Demond White had 11 points and Tyler Dancy chipped in with nine for the Maroons. Alton had three players reach double figures in Carlos Anderson (19), Darrius Edwards (17) and D'Antae McMurray (13).
Waterloo 45, Jerseyville 39
The Bulldogs nailed down the championship in the rugged Mississippi Valley Conference with a hard-earned win over visiting Jerseyville.
Waterloo, which also defeated the Panthers 53-44 in the teams' first meeting, improved to 17-8 overall and 7-2 in the MVC. Jerseyville slipped to 17-10 and 5-4.
Jerseyville led 17-15 at halftime after limiting Waterloo to just two second-quarter points. But the Bulldogs outscored the Panthers 15-8 in a resurgent third quarter and maintained control.
Shane Lenhardt scored a game-high 18 points for the Bulldogs. Kyle Steckel had 13 points and Luke Shively had 12 for Jerseyville.
Both teams will close out the MVC portion of their schedules Friday night before the Class 3A playoffs begin next week. Waterloo will be in the Althoff Regional, while the Panthers will play in the Triad Regional.
Gibault 62, Marissa 25
In the Class 1A Lebanon Regional, the second-seeded Hawks had no trouble against Marissa as they reached the semifinals.
Wes Degener scored 18 points and Nick Row had 16 for the Hawks (21-8), who will face No. 3 New Athens (13-11) at 8 p.m. Tuesday.
In the other semifinal Tuesday, fourth-seeded Lovejoy will play top-seeded Okawville at 6 p.m. The winners will meet in the championship game at 7 p.m. Friday.
