There were a couple players on the Destrehan roster with the same jersey number.

The No. 5 wasn’t one of them, although it may have seemed that way at times the way Chad Serrano dominated early.

The senior had an interception, caught a touchdown pass and scored on special teams to jumpstart Destrehan, then the Wildcats exploded in the third quarter to turn what was supposed to be a Super 10 showdown into a rout.

Final score: Destrehan 38, Ehret 18.

Serrano, whose mother is in the military, moved to Destrehan from North Carolina last year, but was starting for just the third time of his career.

“It was definitely my best game,” said Serrano, who plays cornerback and running back. “We just came out with intensity. We have been practicing for this team and we came out with intensity and fire because we knew they were good.”

Destrehan (3-0), ranked No. 4 in the Super 10, continued its regular season dominance. The Wildcats haven’t lost a regular season game on the field since a 2012 loss in the regular season finale against Hahnville. (They had a forfeit loss to South Lafourche in 2013).

It was the defense leading the way as the Wildcats held Ehret to just 77 yards in the first half.

“I think the defense played phenomenal the whole night,” said Destrehan coach Stephen Robicheaux.

It was the defense of fifth ranked Ehret (2-1) looking stout early.

The Patriots stuffed Destrehan on fourth and short on three straight possessions in the opening quarter.

But the Wildcats finally broke through in the second quarter, putting together an 86-yard drive.

Kohen Granier, who completed 8 of 18 passes for 167 yards and three touchdowns, capped the drive by floating a pass to Serrano who then outran the Ehret secondary for a 22-yard score.

Serrano, who plays both ways, also had an interception late in the first quarter.

Hunter Breit kicked a 25-yard field goal with 1:04 left in the first half to give the Wildcats a 10-0 lead.

Then the Wildcats broke things open early in the third.

Serrano stripped the ball from the Ehret returner on the second-half kickoff and returned it 35 yards for a touchdown.

“He was all over the field,” Robicheaux said. “He had a tremendous night. We ask him to do a lot and he responded tonight. …We always talk about the first three minutes of the second half are important. That touchdown put some separation between us.”

The Wildcats tacked on two more touchdowns in the next five minutes.

The first came on a 35-yard pass from Granier to John Williams.

The duo hooked up again for a 69-yard touchdown pass early in the fourth quarter.

Krsitian Mosley also had a short touchdown run in the half .

The Patriots were playing without quarterback Ca’Ron Baham, who tore his ACL in the season opener against Riverside. They won their first two games without Baham, a Missouri commitment, but struggled to out together much offense in this one.

Juwan Leoanard completed just 2 of 9 passes for 26 yards before being replaced by freshman Travis Mumphry in the third.

Mumphry led the Patriots on a touchdown drive, hitting Tyron Williams for a 9-yard touchdown with 4:10 left in the third. Mumphry later connected with DeJon Harris for a 12-yard TD pass and a 1-yarder, but it was much too little, much too late.

“Once we got behind, we knew we were in trouble without our big gun guy,” Ehret coach Corey Lambert said. “But I found my quarterback. We are going to work with him and slow the game down and we’ll be able to run the ball and throw the ball. We’re going to be back.”

Both teams begin district play Friday.

Ehret plays East Jefferson at Yenni Stadium, and Destrehan makes the short trip to play rival Hahnville.

“It’s Hahnville-Destrehan, so it’s a lot of fun,” said Robicheaux.
