The Trojans (7-2, 6-1) are now alone atop the standings after Etowah — the co-leader coming into Friday’s action — lost to Walton 28-5 to fall into a tie for second with the Raiders and Milton.
Lassiter can now clinch the 5AAAAAA title and the top seed from the region in the Class AAAAAAA playoffs with a win over Etowah in its regular-season finale next Friday.
“It was a big win for us and now we have to come back and play our best against Etowah next week to win the region title,” Lassiter coach Jep Irwin said.
Will Anderson completed 22 of 39 passes for 182 yards, throwing for one touchdown and running for another, to lead the Trojans.
Lassiter got on the scoreboard first and took a 7-0 lead when Anderson threw a 5-yard touchdown pass to Blake Wilson and Luke Hardin kicked the extra point with 7:52 remaining in the first quarter to complete a 13-play, 68-yard drive.
Roswell came back to tie the score at 7-all when Mechane Slade scored on a 5-yard run and Shavi Bush made the extra-point kick with 3:08 left in the first quarter.
Anderson led Lassiter to its next score when he completed three straight passes — the last one for 19 yards — to move the ball to the Roswell 4 and then ran the ball into the end zone himself on a quarterback keeper with 8:30 remaining in the first half. Hardin converted the extra-point kick to give the Trojans a 14-7 advantage.
Lassiter added to its lead towards the end of the first half as Hardin kicked a 33-yard field goal with 12 seconds left to make the score 17-7 at halftime.
Roswell came back on the first offensive series of the fourth quarter as Bush booted a 22-yard field goal with 9:54 left in the game to cut Lassiter’s lead to 17-10.
The Hornets made one more final drive to the end zone as they went on a 14-play, 68-yard drive that took the ball all the way down to the Lassiter 12.
Roswell went for it on fourth down and 7 at the Trojan 12 with 2:12 left in the game, but Matt Cory threw an incomplete pass to end the Hornets’ drive and seal the win for Lassiter.
“Our defense played really well,” Irwin said. “Our defense was great in the second half and they did a good job of holding Roswell off on that final drive in the fourth quarter.”
