The fifth-seeded Simpson Academy Lady Cougars pulled off perhaps the biggest upset of the MAIS District 4-AAA Tournament at Brookhaven Academy Friday night as they stunned the top-seeded Adams County Christian School Lady Rebels 51-45 in the girls’ semifinal round.

The first half proved to be the determining factor in the outcome of this game. ACCS could not generate much offense in the first quarter and found itself trailing Simpson Academy 12-6 at the end of the period. The Lady Cougars continued their momentum in the second quarter as they outscored the Lady Rebels 18-13 for a surprising 30-18 halftime led.

ACCS got back to playing better defense in the third quarter and that allowed the Lady Rebels to cut into the lead. They scored 14 points while holding Simpson Academy to just eight points to make it a 38-33 game. The Lady Cougars responded then with a 13-12 edge in the fourth quarter.

Bailey Boyd led ACCS (21-5) with 16 points and Lexi Emanuel poured in nine points. The Lady Rebels will take on cross-town rival Cathedral at 2 p.m. today in the girls’ consolation game.

Cathedral, the No. 3 seed, hung tough with No. 2 seed Columbia Academy in the first half and was only down 26-21 at halftime. But the third quarter is when the game got away from the Lady Green Wave after it was held to just four points while the Lady Cougars put up 13 points for a 39-25 advantage.
