Santa Margarita Catholic High School has turned its 2026 football season into one of Southern California’s defining high school stories. The Eagles defeated JSerra Catholic 36–12 on Friday, October 23, at Saddleback College in Mission Viejo, California, improving to 9–0 overall and 4–0 in Trinity League play. The victory also secured at least a share of the program’s second consecutive Trinity League championship.
The result extended Santa Margarita’s winning streak to 15 games and reinforced a pattern that has defined its season: a defense capable of limiting opposing offenses, a rushing attack that can control possession, and special-teams plays that change momentum. Even a lightning delay lasting more than an hour and persistent first-half rain could not derail the Eagles against JSerra.
The final score was decisive, but the game did not begin that way. Santa Margarita needed to overcome an early turnover, withstand JSerra’s opening touchdown, and find its rhythm before producing a 20-point fourth quarter. The performance showed why the Eagles have become more than an undefeated team chasing another league trophy.
Santa Margarita’s Defense Set the Tone Against JSerra
The Eagles’ defensive performance was central to the 36–12 victory. According to the team’s official game report, Santa Margarita outgained JSerra 327 yards to 121 and held the Lions to just 69 rushing yards. JSerra gained 30 yards on its final drive, meaning Santa Margarita had limited the opposition to fewer than 100 rushing yards in every game of the 2026 season through October 23.
That consistency has given the Eagles a reliable foundation. Offenses can generate isolated completions or find space on a broken play, but sustaining drives becomes much harder when the defense repeatedly wins at the line of scrimmage and forces opponents into difficult passing situations.
Freshman linebacker Aydan Steen contributed two tackles for loss on JSerra’s opening possession. Freshman edge defender Kaleb Herndon also made a substantial impact, finishing with eight tackles, two tackles for loss, a pass defensed, and 1.5 sacks. His pressure helped produce an intentional-grounding penalty in the end zone, resulting in a safety that brought Santa Margarita closer after the Eagles had fallen behind.
Defensive lineman Tonga Uhila disrupted the Lions in several ways, recording a forced fumble, a quarterback hurry, four tackles, a tackle for loss, and a pass defensed. His forced fumble later helped create one of the decisive scoring plays of the night.
The defensive unit’s contribution was not limited to stopping JSerra. By creating pressure, shortening possessions, and giving the offense favorable opportunities, Santa Margarita repeatedly placed the Lions in situations where one mistake could change the game.
Adrian Petero Gave the Eagles a Dependable Ground Game
Running back Adrian Petero provided Santa Margarita with a steady offensive presence as the Eagles adjusted to the wet conditions. He finished with 19 carries for 114 yards and scored the team’s first offensive touchdown, a nine-yard run around the right end with 54 seconds remaining in the first half.
Petero’s production mattered because the game’s early conditions favored a controlled approach. Lightning delayed the contest for more than an hour, and steady rain complicated ball handling and field conditions during the first half. In that environment, a dependable rushing attack helped Santa Margarita advance without requiring every possession to depend on long passing plays.
The Eagles also benefited from quarterback Fletch Palmer’s ability to connect with his receivers when the opportunities appeared. Palmer completed 14 of 23 passes for 174 yards and one touchdown. Grant Mosley led the receiving group with seven catches for 71 yards, while Grant Van Raaphorst added three receptions for 75 yards.
Palmer found Van Raaphorst for completions of 42 and 18 yards during a second-quarter drive, moving the Eagles into scoring territory. Although that possession ended with a missed field goal, the passing game helped Santa Margarita generate field position and put pressure on JSerra’s defense.
Mosley later caught an eight-yard shovel pass for a touchdown, extending Santa Margarita’s lead to 23–6 in the third quarter. That score capped a 10-play, 60-yard drive that consumed 4 minutes and 13 seconds. The possession illustrated how the Eagles could combine controlled execution with enough variety to keep the defense responding.
Special Teams and Defensive Scores Changed the Game
Santa Margarita’s biggest advantage emerged after halftime, when the Eagles turned field position and defensive pressure into points.
Junior Luca Amaya opened the second half with a 94-yard kickoff return for a touchdown, according to the detailed game narrative. The score increased the Eagles’ lead to 16–6 and immediately placed JSerra under greater pressure. Rather than needing a long offensive possession to create separation, Santa Margarita scored on the opening play of the half.
The defense then continued to limit the Lions’ options. JSerra’s first two second-half possessions ended in punts, while pressure from Herndon, sophomore linebacker Dax Karney, and Steen disrupted quarterback Hayes Cloutier’s attempts to sustain drives.
The decisive defensive play came with 9:06 remaining in the fourth quarter. Jimmerson pursued Cloutier in the backfield, and Uhila forced a fumble. Jimmerson recovered the loose ball and returned it 79 yards for a touchdown, pushing the lead to 29–6.
That play demonstrated the value of a defense that continues to pursue the ball after the initial rush. Uhila created the turnover, while Jimmerson turned it into a score. Santa Margarita had now received points from its defense and special teams, reducing the burden on Palmer and the offense.
Jaion Smith added another touchdown on a 28-yard run with 4:28 remaining, completing a 48-yard drive and stretching the margin to 36–6. JSerra scored on the final play of the game, leaving the final score at 36–12.
The Eagles scored 20 points in the fourth quarter alone. Their ability to create explosive plays on three different phases of the game turned a competitive first half into a comfortable victory.
The St. John Bosco Win Had Already Changed Santa Margarita’s Season
The JSerra victory followed another major result: Santa Margarita’s 21–7 win over St. John Bosco on October 16. That victory improved the Eagles to 8–0 and ended a 16-game losing streak in the series dating back to 2011. It was also the program’s first win at St. John Bosco since 2010, according to the school’s official report.
The Eagles’ performance against Bosco had already established their ability to win a high-stakes game against a traditional Trinity League power. Santa Margarita limited the Braves’ offense, created a defensive touchdown through an interception return, and added scores through Petero and a long touchdown reception by Mosley.
The victory over JSerra then showed that the team could maintain its focus the following week, even with the pressure of an undefeated record and a championship opportunity.
That sequence matters because successful high school programs must handle different kinds of challenges over the course of a season. Beating a highly regarded opponent can validate a team’s potential, but following that result with a disciplined performance against another league rival requires preparation and consistency.
Santa Margarita’s 9–0 record reflected both accomplishments. The Eagles had won close games, including a 21–20 result against Corona Centennial on August 28, while also producing shutouts against Highland, Inderkum, and Norco. The 14–7 victory over Mater Dei on October 2 and the 27–3 win over Servite on October 9 helped establish their position before the final stretch of league play.
What the Trinity League Title Share Means
The win over JSerra secured Santa Margarita at least a share of its second consecutive Trinity League championship. The distinction is significant because the league includes established Southern California programs such as Mater Dei, St. John Bosco, Orange Lutheran, JSerra, and Servite.
A shared championship does not mean the regular season is complete or that every postseason objective has been achieved. Santa Margarita still had one league game remaining, against Orange Lutheran on Friday, October 30, at Orange Coast College. The Eagles entered that matchup seeking to finish league play 5–0, a result the team’s official report noted would make it only the third time in program history—and the first since 1997—that Santa Margarita completed a league schedule without a loss.
That next game also carries implications beyond the title share. Finishing the league schedule unbeaten would give Santa Margarita another strong result before the CIF Southern Section playoff draw, scheduled for November 1. The postseason brings a different challenge, where one loss can end a team’s championship pursuit and opponents have less room for mistakes.
The Eagles’ 2026 profile gives them reasons for confidence. They have shown they can win in close contests, control the ground game, pressure opposing quarterbacks, and score through the offense, defense, and special teams. Their ability to limit rushing production has also helped prevent opponents from controlling the tempo for extended stretches.
Still, the final regular-season game remains important. Orange Lutheran provides Santa Margarita with another opportunity to test its execution against a Trinity League opponent before the playoffs begin. Maintaining ball security, limiting penalties, and continuing to finish defensive possessions will be essential as the competition intensifies.
Santa Margarita’s Undefeated Record Is Built on More Than Scoring
Santa Margarita’s 36–12 win over JSerra was a clear result, but the underlying numbers explain why the Eagles have reached 9–0. They outgained the Lions by 206 yards, held the rushing attack below 100 yards for the ninth consecutive game, and produced touchdowns through a kickoff return, a fumble return, and multiple offensive possessions.
Those details point to a team with several routes to victory. If the passing game slows, Petero and the rushing attack can sustain drives. If the offense stalls, the defense can create short fields or score directly. If the opponent gives up a return opportunity, the special teams can change the scoreboard in seconds.
The next test is whether Santa Margarita can carry those strengths through its final league game and into the CIF Southern Section playoffs. The championship share is already secured, but a 5–0 league finish and a deeper postseason run would give the Eagles additional opportunities to define what has become a landmark season for the program.
For now, the win over JSerra confirms that Santa Margarita has combined defensive consistency with timely explosive plays to maintain its unbeaten record. The Eagles have earned their place at the top of the Trinity League standings, and their final regular-season performance will help determine how much momentum they take into November.
