Second-seeded Waynflete (19-1) got 16 points from Diraige Dahia and huge contributions from several reserves in a Class C South semifinal win over the third-seeded Seahawks (15-5) at the Augusta Civic Center.

Aided by strong minutes from bench players Ilo Holdridge, Aidan Kieffer and Chris Saade, the Flyers advanced to face top-seeded Winthrop or No. 4 North Yarmouth Academy in Saturday’s regional final.

Waynflete led 14-13 after one quarter, then got a little breathing room in the second quarter with nine straight. After Boothbay closed within four, a putback from Saade and a pair of free throws from Kieffer made it 27-19 at halftime.

Both offenses bogged down in the third quarter, as the teams combined for 10 points. The Seahawks crept within five on a Nick Morley 3-pointer, but a three-point play by Holdridge allowed Waynflete to maintain a 32-24 edge heading into the fourth quarter.

Dahia scored eight points in the fourth to keep Waynflete in control.

Boothbay was paced by Hunter Crocker with 11 points.
