When the Wolfpack senior's banked shot just missed, the Knights finally were able to breathe a sigh of relief after a wild second half.
In the end, Evans withstood several lengthy Greenbrier runs and made its free throws down the stretch in an 83-80 home win.
"It seemed like everybody was just making their shots," said Evans senior Trevor Foreman, who made a pair of free throws with 11 seconds left to extend his team's lead to four.
"We were just trying to go back at them because nobody was really playing any defense."
The Knights (14-7, 3-3 Region 2B-AAAA) got back to .500 in the region after starting 0-3.
"We're making a major comeback," said senior Austin Sandifer, who made five of Evans' nine 3-pointers while exploding for a game-high 27 points.
After Foreman's free throws, Waddell hoisted a 3-pointer near mid-court.
He made it -- his fourth 3 of the game -- with 6 seconds left to get within a point.
Myles McDavid made a pair of foul shots, then both turned it over once before Waddell's shot.
"I only had 2 seconds and I caught it running down the sideline," said Waddell, who had a team-high 20 points for Greenbrier. "I knew I just had to put it up."
The Wolfpack got 19 points apiece from Justin Cofer and Thomas Brown. Despite the loss, Greenbrier (15-6, 4-2 Region 2B-AAAA) remains among the top two in the region standings alongside Effingham County.
The Wolfpack were without senior forward Dejon Britton, who was ill.
In girls' action, sophomore Deztinie Cotton returned from injury in a big way, scoring a game-high 15 points in a 33-32 road win at Evans.
Greenbrier (4-17, 1-5 Region 2B-AAAA) had been without Cotton for a month because of a severe high ankle sprain.
Upon her return, she consistently got to the free-throw line and gave Evans fits inside.
"We had to do it for the team," said Cotton, whose two free throws with 35 seconds left won it for the Wolfpack. "We needed a win."
Evans (4-15, 1-5 Region 2B-AAAA) led 29-25 after three quarters, but scored only three points in the fourth.
KiKi Battle had seven points for the Knights.
