The Seahawks are headed to Augusta.

In a stellar second half display of offense and defense, the Boothbay Region Seahawks, seeded 15th, upset second-seeded Old Orchard Beach, 82-75, in overtime to advance to the Class C South quarterfinals at the Augusta Civic Center next week.

Trailing 31-17 at halftime, and by 19 points (36-17) early in the third quarter, coach Dan Hallinan’s team outscored the Seagulls, 27-19, in the third quarter to cut OOB’s lead to 50-44.

A layup by Seahawk senior Ashton McLellan with about four seconds to play sent the game into overtime, 68-68.

With the game tied at 75-75 in overtime, Kayden Ames hit a layup and Boothbay went five of six from the line to seal the victory.
