The Eagles led 14-13 after the first period, but the Warriors then raced away on a 65-22 scoring advantage through the next three quarters to win it going away.
Tim Holmes led the meager MMC scoring with nine points, and Jordan Boekhout tallied seven. Derek Moore led SB-L with 28 points, and Paul Choquette scored 13.
Nate Dammann led the Eagles in rebounds with six points, and Choquette grabbed five for SB-L.
"We played a good first half except for a couple of breakdowns," said MMC coach Al Vasher. "In the second half, we came out a little cold and with very little enthusiasm.
"I thought Sergeant Bluff-Luton raised their intensity and we didn't do a good job of matching it. We need to be able to play with different amounts of emotion at different times of the game."
