Memorial nearly clinched a berth Thursday night before falling to Norman North in overtime.
Saturday, though, Memorial took control by outscoring the Yellowjackets 17-10 in the second quarter and then held on for the win.
Jenny Roy led Memorial with 18 while Andee Decker added 13 and Kaleigh Troxell added 10.
Addie Vernon had 17 and Kylee Hicks added 13 for Choctaw.
HAWKINS LIFTS SOUTHMOORE TO STATE
Not that it's had many years to try, but relative newcomer Southmoore can now shed the label of being the only Class 6A or 5A team to never advance to the state tournament.
Two nights after falling in their initial chance to qualify, the Class 6A No. 4 SaberCats took advantage of their second chance by beating Putnam City 57-48 at Choctaw.
Southmoore jumped on the Pirates early, outscoring them 17-8 in the first and taking a 33-21 lead into the break.
Putnam City pulled within four, 43-39, heading into the fourth quarter but Southmoore held the Pirates off down the stretch to earn the tournament berth.
Serithia Hawkins scored 22 to lead Southmoore. Kyra Gilbert added 16 and Kayla Tucker 12.
Kyra Johnston led Putnam City with 15 points while Jayden Oliver and LaShabra Plunkett scored 11 each.
HERITAGE HALL STAYS ALIVE
With less than a minute remaining in Saturday's Class 4A area consolation game against Elk City, Heritage Hall's season looked all but over.
But the Chargers, down six in the final minute, didn't give up, tying the game on a pair of quick 3-pointers, then Meredith Zerby hit a game-winner with two seconds remaining to lift Heritage Hall to a 33-31 win over Elk City at Yukon.
The basket was Zerby's only two points of the game.
Erika Wakefield led the Chargers with 19, battling through foul trouble in the second half.
Heritage Hall will play Mount St. Mary's at 6:30 p.m. Monday at Yukon for a state tournament berth.
Mount St. Mary's lost to Weatherford, 38-35, in the area final Saturday night.
