Championship leader Kimi Antonelli was handed a late penalty following the Miami Grand Prix Sprint, dropping him down the order in a blow to his title defense.
The Mercedes rookie crossed the line fourth in Saturday’s Sprint race, finishing ahead of teammate and main championship rival George Russell. But in a twist that could have major implications for the 2026 title fight, Antonelli was demoted to sixth after the chequered flag.
Race stewards confirmed the 18-year-old received a five-second time penalty for repeated track limits violations. Antonelli had already been shown the black-and-white warning flag on lap 12 of the 19-lap Sprint, meaning any further infringement would trigger a penalty. He then ran wide again on the final lap, logging his fourth breach of track limits and automatically incurring the five-second sanction.
The penalty dropped Antonelli behind both Russell and Max Verstappen in the final classification. Instead of scoring six points for fourth place, he left Miami with only three points for sixth. Russell, who originally finished fifth, was promoted to fourth and gained two extra points. Verstappen moved up to fifth.
For Antonelli, the timing couldn’t be worse. The Italian came into Miami leading the drivers’ championship after winning the last two grands prix. He also started the Sprint from the front row after qualifying second on Friday. With Mercedes showing strong pace all weekend, he looked set to extend his advantage over Russell. Instead, the penalty cuts his lead and hands momentum back to his teammate.
Track limits have been a major talking point in Miami. The street circuit’s layout, combined with high-speed corners and minimal runoff, makes it easy for drivers to run wide and gain time. Race Control has been strict all weekend, with multiple drivers warned or penalized during practice and Sprint Qualifying.
Antonelli’s situation highlights how costly even small errors can be in the Sprint format. With only 19 laps and points awarded to the top eight, a five-second penalty is enough to lose several positions. His final-lap mistake proved especially painful, coming after he had managed the race well up to that point.
Mercedes will be frustrated with the outcome. The team had both cars running strongly, with Russell finishing just behind Antonelli on track before the penalty was applied. The post-race reshuffle means Russell closes the gap in the standings, setting up an even tighter intra-team battle heading into qualifying and Sunday’s Grand Prix.
For Verstappen, the promotion to fifth is a small boost on a weekend where Red Bull has struggled to match McLaren and Mercedes for one-lap pace. Every point matters in what’s shaping up to be a close championship fight.
Antonelli’s penalty serves as a reminder of how fine the margins are in Formula 1. The teenager has impressed with his speed and maturity since stepping up this year, but Miami showed that experience still counts. Managing track limits under pressure, especially in the closing laps of a Sprint, is part of the learning curve.
The full Sprint results will be updated by the FIA, but the impact is already clear. Antonelli loses valuable points, Russell gains, and the championship fight tightens. With qualifying for the main Grand Prix still to come later on Saturday, Antonelli will need to regroup quickly to avoid losing more ground.
