McLaren said a pit-timing error cost Lando Norris victory at the Miami Grand Prix. Lando Norris said, “We just got undercut,” and team principal Andrea Stella accepted the mistake as the decisive factor.

Norris led large portions of the race in a heavily upgraded McLaren, but Mercedes pitted Kimi Antonelli earlier and executed an effective undercut, helped by a strong out-lap, that put Antonelli back ahead and on to victory. Stella said pitting earlier “probably” would have retained the lead, and Norris called the loss “gutted,” adding “no excuses other than that.”
