Norris says Antonelli undercut cost McLaren the Miami win

Formula 1 strategy can look mystical from the outside, but this one was brutally simple. McLaren had a car quick enough to win in Miami. It didn’t control the pit window. Mercedes did — and Kimi Antonelli turned that into victory. After the race, Lando Norris didn’t dance around it. He said McLaren “just got undercut” and “should have boxed first,” which is about as direct as drivers get after throwing away a win. (formula1.com) ### What actually happened in Miami? Antonelli won the 2026 Miami Grand Prix for Mercedes ahead of Norris, with Oscar Piastri third. The margin at the flag was 3.264 seconds, but that gap flatters how close the fight really was. Norris spent the second half of the race chasing, stuck in the dirty-air problem every F1 driver hates — close enough to pressure Antonelli, not close enough to finish the move.

You stop first, bolt on fresh tyres, and use that extra grip to go faster while the car ahead stays out on older rubber. If the timing works, the trailing driver jumps the oth(formula1.com 1)(formula1.com 2) ### So where did McLaren lose it? Mercedes brought Antonelli in on lap 26 of 57. McLaren waited one more lap before stopping Norris. That sounds tiny, but in F1 it’s huge. Antonelli got the benefit of fresh tyres first, McLaren’s stop for Norris was also slightly slower, and Norris came out only just ahead — which meant he was immediately vulnerable once Antonelli’s tyres were switched on. (motorsport.com) ### Why couldn’t Norris just keep him behind? Because out-laps are the whole point of the undercut. Norris emerged in front, but Antonelli already had temperature in his tyres and attacked straight away through the Esses as they caught traffic. That’s the catch with reacting late — you’re not defending with equal tools. One driver has grip now. The other is still waking the tyres up. (the-race.com) ### Did Norris really think the win was there? Yes — and that’s why he sounded so annoyed. Norris called the race a “mixed bag,” said there were “no excuses other than” the undercut, and gave credit to Antonelli and Mercedes for executing it. That matters because drivers often hide behind tyre life, balance, or traffic. Norris mostly didn’t. He pointed at the call. (formula1.com) ### Was McLaren actually quick enough? Looks like yes. Miami was the first big sign that McLaren’s upgrades had put real pressure on Mercedes. Norris had already taken sprint pole, then won the sprint in a McLaren 1-2 with Piastri second. In the grand prix, he had the pace to stay in Antonelli’s fight all afternoon. This wasn’t a lucky almost-win. It was a weekend where McLaren looked properly back in the conversation. (autosport.com) ### Why does this matter beyond one race? Because Antonelli has now won three grands prix in a row and extended his championship lead to 20 points. But Miami also showed Mercedes is no longer cruising. McLaren brought upgrades, found speed, and still left without the big trophy on Sunday. That’s encouraging if you’re McLaren on performance — and frustrating if you’re McLaren on operations. (formula1.com) ### Bottom line? Miami didn’t reveal a slow McLaren. It revealed a fast McLaren that blinked first — or really, blinked second. Antonelli and Mercedes were decisive in the one phase that decided the race. Norris knew it. And in a title fight, the painful weekends are often the ones where the speed was there.
