The Lady Jackets had to settle for the runner-up spot from Region 4-AA after falling in overtime to Livingston.
Grundy (23-9) had a chance to win the game in regulation, but missed a layup. Livingston (31-3) took advantage of the second life and rolled in overtime to the region title. Sydney Staggs led the winners with 15 points, with Abby Miller adding 14. Chelsey Wiseman had a game-high 24 and Macey Weeks added 20 for Grundy, which will play at McMinn Central in the sub-state round Saturday.
LaFayette boys fall
A 30-3 advantage in the third period ended any upset hopes the No. 4-seede Ramblers had in the Class AAA second round. LaFayette, which had upset third-ranked Walnut Grove in the first round, held an early 8-3 lead and trailed just seven at the half before the host Bulldogs (20-9) went on their run.
Walter Jones led Washington, which will face Region 7 champion Allatoona Saturday at the Northwest Georgia Trade Center in Dalton, with 21 points. Devarus Porter topped 20-7 LaFayette with 13 points.
Columbia 71, Dalton 54: The top-ranked and defending state champion Eagles, ranked as high as 11th in the country by one national poll, eliminated the visiting Catamounts, but not without a fight.
Dalton (21-9) trailed 38-22 at the half, but hit three 3-pointers to start a third period tun to cut the margin to eight. However, leading scorer Tristen Harrell picked up his fourth foul and Columbia took off.
"The kids played hard," Dalton coach Mike Duffie said. "Tristen was the best player on the floor. We were down eight with two minutes left in the third and he got his fourth foul. I pulled him and they went on an 8-0 run."
Harrell led Dalton with 20 points, but star junior point guard Tahj Shamsid-Deen and the Eagles were too much down the stretch.
