Krop’s overtime gamble did not pay off.

South Miami linebacker Korey Moss stopped La’Darius Murray on a two-point conversion try as the Cobras defeated Krop 16-15 on Thursday night at Tropical Stadium.

The Cobras (3-3) opened overtime by scoring on an 8-yard swing pass from Leo Lorenzo to Charlie Simmons.

Krop (3-4) answered with its own 8-yard TD pass from Keon Roman to Murray. But a run up the middle by Murray on the conversion try never really had a chance.

The Cobras, who knocked Krop out of the playoffs last season in the regional quarterfinals, had taken a 9-6 lead on a 14-play, 87-yard drive, which resulted in a 27-yard field goal by Adrian Izquierdo.

Krop tied it with a 38-yard field by Alex Beiner with 3:19 left in regulation. The Lightning had an opportunity to win the game in regulation, but Beiner’s 25-yard field goal try with 15 seconds left was blocked by Jean Concepcion.

The score was tied 6-6 at halftime. Krop scored on its first possession, keyed by a 61-yard touchdown pass from Roman to Jovon Durante.

South Miami seemed poised to tie or take the lead when it earned a first-and-goal from the Krop 7. But the Lightning’s goal-line stand kept the Cobras off the board.

The Cobras’ defense came up with its own big play on an interception by Glenn Roberts, who took the overthrown pass at midlfield and returned it to the Krop 27.

South Miami scored a couple plays later on a 17-yard screen pass from Patrick Coats to Simmons.

•  Reagan 35, Miami Springs 20: Enjoying its best season in the school’s short history, Ronald Reagan continued to roll on as the Bison rang up 344 yards on the ground and moved their record to 5-1 with the win over Miami Springs in a non-district matchup at Milander Stadium.

Led by a pair of rushers who crossed over the century mark — Keenan Springer and Imanuelle Pierre, who finished with 153 and 100 yards, respectively — the Bison built up a 28-7 third-quarter lead before Springs rallied to make a game of it.

Led by quarterback Gerald Anderson, the Golden Hawks (1-5) battled back as Anderson tossed a pair of touchdown passes to Keavantra Floyd.

The first was a 2-yarder on the first play of the fourth quarter, and the second from 12 yards on fourth down to cut the Reagan lead to 28-20 with 7:13 left.

But, after Esteban Amorosi’s 40-yard kickoff return set Reagan up with a short field, the Bison went 35 yards in seven plays, quarterback Nick Gomez sneaking over from a yard out on fourth down with 4:32 left to lock the game up.

• North Miami 40, Mourning 0: North Miami head coach Ed Williams’ plan of his Pioneers team flying under the radar is beginning to falter.

A week after defeating district foe Hialeah, North Miami rode its momentum and confidence to a 40-0 victory over Mourning at North Miami Stadium.

The Pioneers (3-3, 1-0 District 13-8A) currently sit atop its district, tied with North Miami Beach (3-2, 1-0).

Unheralded North Miami senior running back Romane Charles led with 93 rushing yards and a touchdown — a 40-yard scamper midway through the fourth quarter to put North Miami ahead 40-0 — and scored on a 99-yard punt return early in the second quarter.

Quarterback James Volcy scored four total touchdowns, connecting on three touchdowns passes — a pair to Nesley Ostral — and rushing for another that put the Pioneers ahead 14-0 late in the first quarter.
