St. Anthony's worked hard during the first half on Saturday in order to command a two-touchdown lead against Delbarton.
But during the first portion of the third quarter, the Friars gave it all back.
With the score now tied, it was time for the Long Island team to regroup, and quarterback Greg Campisi made sure that it happened.
The 5-11, 175-pound junior broke off a 58-yard run to the Delbarton 4 yard-line on the third play after the the equalizing score, and Julian Chung scored on a 1-yard run soon after.
Order was restored, and the Friars were on the way to a 35-21 victory in the matchup between metro-area rivals at William O. Regan Field in Morris Township.
"We needed a play," Campisi said. "We needed something to give us a spark. We were a little complacent at the start of the second half and let them back into it."
St. Anthony's avenged a 21-20 loss to Delbarton in last year's season opener. It now leads 4-1 in a series where the road team has won four straight matchups.
"We had to clean a few things up and I'm really pleased at how we responded after they tied it," St. Anthony's coach Rich Reichert said.
Senior back Sean Bryan ran 22 times for 239 yards and scored once for the Friars.
Chung, meanwhile, had eight catches for 103 yards, and the senior also rushed seven times for 21 yards and two more TDs.
St. Anthony's opened a 7-0 lead just 1:21 into the game when Campisi (15-of-23, 154 yards) hit Chung for a 9-yard touchdown strike. It game two plays after Bryan ran 65 yards to the Delbarton 9 on the second play of the game.
The Friars increased their lead to 14-0 with 5:25 left in the half on another critical play by Campisi.
With his team faced with a third-and-25 at the Delbarton 35, Campisi kept the ball and broke loose along the right sideline for a touchdown.
Aside from his solid, turnover-free passing performance, Campisi also ran seven times for 119 yards.
"He's a player," Reichert said. "He's very athletic, he throws the ball and can run. He's also smart, he's going to Harvard."
Delbarton, which was without senior linebacker/running back Cole Kreshpane (hamstring), opened the second half with a seven-play, 80-yard drive that was capped by a 52-yard TD run from Mashod Harrison with 9:09 on the clock.
The Green Wave got the ball back following a punt two minutes later. Starting at its 28, Delbarton needed 10 plays to get the tying TD, when QB Miles Leniw hit Trey Zgombic for 9-yard score on a fourth-and-6. Ryan Saik hit the extra point for a 14-14 tie.
St. Anthony's responded with the go-ahead TD soon after, and a third-down sack by Grayson Cherubino on Delbarton's ensuing series forced a punt with under 10 seconds left in the quarter.
The Friars then began at their 49, and Campisi immediately ran for 11 yards. Eight plays later, Chung scored from seven yards out for a 28-14 spread with 8:43 left.
Delbarton then drove down to the Friars' 16, but a fourth-and-6 pass went incomplete with 5:36 remaining.
Bryan picked up three yards on the next play, before breaking off an 81-yard TD dash on second down.
Delbarton closed within 14 points after Leniw (16-of-27, 198 yards) completed a 28-yard scoring pass to Lucas Ungar with just over three minutes to go.
