Using a pair of home runs by Chad Thornhill, including a second-inning grand slam, Greenbrier stormed by region rival Lakeside, 13-4, on Monday.
The Wolfpack avenged last week's 4-3 Region 3-AAAA loss and knocked the Panthers out of a first-place tie with Statesboro in the region standings.
While last week's game didn't unfold until late, Lakeside coach Jimmy Smith needed only two innings Monday to figure out his squad was in trouble.
"You can't really go by what happened in the game before," Greenbrier coach Ed Williams said. "Every game is different. Fortunately we were able to come out and get a big region win. There were so many people that helped get the victory."
Thornhill, Greenbrier's first baseman, took Mike Norland for a solo home run over the center-field fence in the first inning to put the Wolfpack on the board first.
After Norland tied the contest with a solo shot of his own in the second inning, the Panthers lefty slowly got into trouble, walking Nick Wandless to lead off the bottom of the inning.
Wandless advanced to third base on Robert Davis' bunt and Philip Tapley's groundout to first. That brought up Alan Cannell, who doubled off the right-field wall to score Wandless and give Greenbrier a 2-1 advantage.
"Chad and Alan had some big hits," Williams said. "It was great to see Thornhill have a strong day after not swinging well in the last couple of weeks."
Seth Newsome walked next, and Bradley Key got to first on a choppy infield single to load the bases with two outs. Norland walked Chris Wilson to score Cannell, bringing up Thornhill with the bases loaded.
With one ball and one strike, Thornhill connected on Norland's third pitch, launching the grand slam high over the right-field fence to give the Wolfpack a convincing 7-1 lead after two innings.
"I told him to make him hit the curve, and he did," Smith said. "Mike didn't have much on it, and Greenbrier is hitting the ball extremely well. That was five runs right there from Thornhill. They answered everything we had."
Thornhill was 2-for-3 with five RBI.
The Wolfpack tacked on three more runs in the bottom of the third to take a 10-1 lead after John Seebode relieved Norland with two runners on base. Cannell, Seebode's first batter, rocked his second double of the day to center field, this time scoring Tapley and pinch-runner Mike Walden.
Cannell was 3-for-4 with three RBI as the Wolfpack ran through four Lakeside pitchers. Meanwhile, Greenbrier's Bradley Key (6-2) went the distance, giving up just five hits and three earned runs.
"To me, he's the best pitcher in the area," Smith said. "He's the guy you want on the mound. We couldn't do anything with him, but that happens. You lose big some nights, and you win big. We have to move on."
