After seeing many of the frontrunning drivers pit with round 20 laps to go for a contemporary set of intermediate tyres, Mercedes opted to maintain Hamilton out as he felt his tyres had been nonetheless in ok form.
The staff thought-about preserving Hamilton out all the way in which to the top of the race, solely to finally pit him with eight laps remaining after he began shedding time to the vehicles chasing him.
Hamilton had risen to 3rd place earlier than pitting, however misplaced locations to Sergio Perez and Charles Leclerc after making the swap. He got here beneath late stress from Pierre Gasly for fifth place as he struggled with graining.
Hamilton informed Mercedes over the radio that he “shouldn’t have are available in” and was pissed off after shedding the lead of the drivers’ championship to Max Verstappen.
The one driver to finish the race with out pitting was Esteban Ocon, who completed tenth for Alpine. However he conceded his tyres had been “fairly broken” by the top, and believed he would have sustained a puncture had the race lasted one lap longer.
Mercedes trackside engineering director Andrew Shovlin defined that the drop-off in Ocon’s lap instances in direction of the top of the race proved how dangerous it might have been to maintain Hamilton out.
“In the event you have a look at Esteban, he obtained overtaken by Lance [Stroll] about 5 – 6 laps from the top, and he completed 17 seconds behind him,” Shovlin mentioned.
“That’s how rapidly you fall off. That’s what’s in our thoughts, it’s not simply if we will maintain going at this tempo.
“Esteban misplaced an additional two seconds in that brief run to the end, and that’s the place it goes fallacious.
“We’ll undergo it and examine, however we’re pretty sure we might have misplaced these two locations, if not been in danger from extra.”

Ocon’s instances nosedived in direction of the top of the race as he misplaced greater than three seconds per lap to Stroll forward. Antonio Giovinazzi completed narrowly behind Ocon in eleventh, and felt he wanted yet one more lap to grab a degree from the Alpine driver.
Hamilton’s instances on worn intermediates had been similar to those that had pitted for some time, however as soon as they had been by the graining part, the lap time loss pressured Mercedes to behave.
“I feel 10 or 11 laps to the top, or 12 laps to the top, we thought that his laps instances had been truly fairly robust,” mentioned Mercedes F1 boss Toto Wolff.
“They had been like Perez behind him, 34.6s, 34.7s. After which out of the blue it began to drop off.
“When Perez introduced his intermediate into the window and went by the graining part, we had been shedding 1.5 seconds or 2 seconds per lap, and it was clear that we had been going to lose that place, most likely [also to] Leclerc, and likewise Gasly.”
