Unranked Washington got 21 points from Darius Miles and used its speedy, aggressive defense to upset No. 6 Allatoona 59-56 in the Class AAA quarterfinals at the Northwest Georgia Trade Center in Dalton.

“Our guys just wanted it,” Washington coach William Faulkner said. “They were going to fight to the end. That’s the Booker T. Washington way.”

Washington’s boys advanced to the semifinals for the first time since winning the Class AAAA title in 1987.

The Bulldogs (20-9) led by as many as seven points (51-44) in the fourth quarter, but never could shake the Buccaneers (26-5).

Allatoona cut the lead to one on two occasions and missed two 3-point shots in the final seconds that would have forced overtime.

The Bucs were led by Dimychael Ross with 22 points.

Georgia Tech signee Chris Bolden scored 28 for North Gwinnett (21-9). Milton point guard Charles Mann, who has signed with Georgia, was ejected in the third quarter for a second technical foul after hanging on the rim after a dunk. The ejection means he must sit out two games, ending his season.

Savannah 59, North Cobb 43: In Fort Valley, Kavon Freeman scored 14 points, Jamal Norman 12 and Russell Famble 10 for unranked Savannah (29-2), which outscored No. 2 North Cobb 17-1 over the final 3:07 to earn its first appearance in the state semifinals since 2008.

Saxon Steele scored 17 points and Lee Moore 10 for the Warriors (26-5), who led for most of the first half.

Eagle's Landing 68, Crisp County 66: Marquis Griffin's bucket-and-one with :15 seconds left in regulation broke a 65-65 tie and propelled the Golden Eagles to their second consecutive state semifinals. Crisp County (17-10), which battled back from a 13-point deficit in the third quarter, had one final chance to win the game on an in-bounds play with .7 seconds left, but Javoris Cooks' desparation 3 was short at the buzzer.
