Bell City, a Class 1 team, had a 54-52 advantage with just over six minutes to play, but Doniphan (22-3 and ranked No. 6 in Class 3) sank the Cubs with a 14-2 run over the next 3 minutes.
Jeff Liggins led the Cubs with 19 points. Nick Niemcyzk netted 18, and Phillip Gross added 10.
Scott City rallied from a 14-point deficit in the final 3 minutes and 45 seconds to win at Caruthersville.
Sophomore Alex King capped the comeback with a layin with 4 seconds left off a pass from Andy Stephens.
