Madisen Coulter scored six of her game-high 15 points in overtime Tuesday night to lift the South Fulton girls basketball team to a 41-30 upset of Illini Bluffs at the Class 1A Glasford Regional.

The eighth-seeded Rebels led after each of the first three quarters, but went 2-of-7 from the line in the fourth as the Tigers pushed to force the extra period.

It was a different story in OT, however, as 10-of-14 foul shooting by the Rebels helped send the second-seeded hosts packing.

Amanda Parker added 10 points for South Fulton, which will take on third-seeded Brown County at 7 p.m. Thursday for the regional title.

Hannah Hicks had 11 points to pace the Tigers.

AT VARNA

PRINCEVILLE 74, MIDLAND 37: The  top-seeded Princes led 41-11 at the half on the way to doubling up the host Timberwolves in the first 1A semifinal of the night.

Lucy Waid scored a game-high 18 points to lead a group of four double-digit scorers for Princeville, with Caitlin Pullen adding 15, Brinlee Bauman 14 and Marisa Horton-Meza a dozen.

Kaye Brown scored 15 points on five 3-pointers for Midland.

ELMWOOD 41, GALVA 34: The regional's No. 4 seed will play Princeville for the title on Thursday after outlasting the fifth-seeded Wildcats in the nightcap. The Trojans, who suffered a 16-point loss to Galva back in late December, broke from from a 13-13 halftime tie to avenge the defeat.

AT TREMONT

MIDWEST CENTRAL/DELAVAN 68, TREMONT 55: Mady Harper had herself a night, scoring a game-high 25 points and her 1,000th career point to lead the Raiders past the host Turks in a Class 2A semifinal.

Harper, whose 1,000th point came on a fourth quarter free throw, had 11 points at halftime as third-seeded Midwest Central rolled out to a 35-21 lead by intermission.

Vanessa Ehnle scored 21 points for Tremont, which failed to make a dent in the Raiders' lead until the fourth quarter.

Midwest Central will play second-seeded El Paso-Gridley, a 40-18 winner over Olympia, at 7 p.m. Thursday in the championship.
