Kimi Antonelli's Miami weekend ended with a third Grand Prix victory and a championship lead in his pocket. It almost ended very differently. The Mercedes rookie was the headline name on the stewards' Saturday paperwork, with a post-race five-second time penalty for excessive track-limits breaches dropping him from third to sixth in the 2026 Miami Formula 1 sprint.
The penalty, applied after the chequered flag, swung the championship picture more than the result of the sprint itself suggested. Teammate and closest title rival George Russell was promoted to fourth, and Max Verstappen's recovering Red Bull also gained a place to fifth.
The stewards' decision arrived on top of an already chaotic sprint. Red Bull turned up in Miami with what looked like the team's first genuinely competitive package of the year, and Verstappen was openly more positive about the car's behaviour after weekends of midfield invisibility.
"Going into Miami, Red Bull have really improved their car," James of the James' Pit Lane channel observed in his sprint review. "In the opening three rounds of the season, they were a midfield team. The car was absolutely nowhere and Verstappen and his teammate Isack Hadjar were not happy with it. But in Miami, things have changed. Red Bull have brought major upgrades to the car. The car looks more together and Verstappen looks more comfortable."
That newfound comfort manifested itself in a hard scrap with Lewis Hamilton, with both drivers running off circuit at one point during their wheel-to-wheel battle. Stewards judged the incident as racing and chose not to penalise either side.
Antonelli's case was less ambiguous. Drivers in 2026 are working with smaller margins for error at high-speed run-off areas, and the Miami circuit's repaved sections punished the Italian over the course of the 19-lap sprint. The five-second penalty applied after the flag was the cumulative consequence of multiple warnings during the race.
"After the race, there was confirmation from the stewards that Antonelli had been given a five-second time penalty for excessive track-limits breaches," the same review noted. "That dropped Antonelli to sixth in the sprint, with his championship rival Russell moving up to fourth and Verstappen into fifth. So a very costly penalty for Antonelli there. And that costs him in the championship as well, with Russell closing in on him."
The Italian's response was emphatic — Sunday pole, Sunday win, championship lead extended again. But the penalty itself underscores a vulnerability the teenager will need to clean up for the second half of the season, where stewards have historically applied even tighter calls. For now, his cushion in the standings is enough to absorb a Saturday wobble. It might not always be.
