PORTLAND — Scarborough’s fourth-ranked girls’ basketball team held No. 5 South Portland to just one basket and forced seven turnovers in the first quarter of Monday evening’s Western Class A quarterfinal round game at the Portland Exposition Building.

Problem was, the Red Storm only had two points of its own.

Scarborough finally turned things around in the second half, got its offense in gear thanks in large part to senior Taylor LeBorgne and pulled away to prevail, 45-32.

The Red Storm improved to 16-3, ended the Red Riots’ season at 12-7 and advanced to meet either top-ranked, undefeated, two-time defending state champion McAuley or No. 8 Gorham in the semifinals Friday at 6 p.m., at the Cumberland County Civic Center.

After its tough start, Scarborough was down, 6-4, early in the second period, but went on top for good when senior Mary Redmond made two free throws. By halftime, the Red Storm was up, 21-11, as LeBorgne had seven points and Scarborough forced 20 South Portland turnovers.

The Red Storm tried to open it up in the third quarter, but the Red Riots hung within 10 most of the way. Leading, 33-22, entering the fourth, Scarborough scored the first six points to put it away.

Sophomore Ashley Briggs led all scorers with 10. LeBorgne, Redmond and senior Maria Philbrick each added nine for Scarborough.

South Portland was paced by eight points from freshman Maddie Hasson. The Red Riots finished with 29 turnovers.
