The Lady Spartans (17-8) were sparked by strong nights from Ciara Lyons and Jessica Morton to earn a semifinal clash Friday against the winner of Thursday's Harlem-Liberty County game.
"The girls all kind of came together," Glenn Hills coach Bernard Bowman said. "The passing was there in a group effort."
Morton led with 19 points. Her 13 points in the second half made sure a 44-28 halftime edge never wavered.
Lyons scored 15 of her 17 points over the first three quarters against an improving Washington County team under first-year coach Faye Norris.
Bowman said the plan was to hem in Washington County's Shakima Wiggins.
"She's a great shooter," he said. "We just had to play a little man-to-man defense and keep her feet from getting set. Coach Norris is doing an outstanding job her first year there. She's an outstanding coach who's only going to keep improving that program."
Wiggins still had 20 points.
HEPHZIBAH 81, CROSS CREEK 49
Hephzibah kept up its Region 3-AAA tournament mastery. Cross Creek essentially saw its playoff hopes shot down.
The Lady Rebels jumped out to a 41-25 halftime lead on the strength of five three-point baskets on the way to the quarterfinal victory. The six-time defending region champions made 10 3-pointers against the Razorbacks.
Hephzibah senior guard Jasmine Judge hit three 3-pointers on her way to 22 points.
Her strong start led to 14 points at the half.
Cross Creek (12-14) was led by Ashley Banks. She scored 12 of her team-best 18 points in the fourth quarter.
Iesha Little also netted 16 points.
Hephzibah will face Butler in the region semifinals tonight.
