Mahtomedi took an 8-6 lead into the fourth quarter at the state lacrosse tournament Tuesday but could not hang on.
The final stanza was dominated by St. Thomas Academy as the Cadets (15-2) sent the Zephyrs (12-6) into the consolation bracket, 11-8, at Chanhassen.
The Cadets, who beat the Zephyrs 10-7 in conference play, were on the ropes in the rematch, but came alive to score all five goals in the fourth quarter.
The Zephyrs had shut them out 2-0 in the third period. The Cadets were bogged down by five penalties in the third period, and nine in the game, while Mahtomedi had just one infraction.
Nathaniel Graslewicz, Levi Lemke and Connor Stoker each scored two goals for Mahtomedi, and Ryan Pilla and E.J. Carpentier one each.
Colin Hagstrom won 17 of 22 face-offs for the Zephyrs. Goalie Gus Magnusson faced 16 shots, stopping five.
Luke Williams wielded the big stick for the Cadets with five goals. Daniel McFadden added three. Baker Redding delivered two straight in the final quarter that gave them a two-goal lead. McClain Beaudette in goal faced 21 shots and foiled 13.
Mahtomedi reached state by avenging a regular-season to Stillwater 13-11 in the section semifinals. Stillwater was 14-0 before that including a 13-6 opening win over Mahtomedi. But the Zephyrs were not quite able to the same against St. Thomas Academy.
Mahtomedi will face Centennial in the consolation bracket on Thursday, 1 p.m., at Minnetonka High School. The winner will play for fifth place on Saturday, 11 a.m., at Minnetonka.
In the other first-round games, Eden Prairie beat Lakeville North 14-10, Prior Lake topped Wayzata 12-4, and top-seeded Benilde-St. Margaret’s scuttled Centennial 8-4.
