The cynic(/romantic?) in me wonders whether the Mercedes strategists are having a bit of a laugh with us this season and deliberately engineering scenarios to create “great” races and great legendary Hamilton performances. Monaco the most obvious example, but now here. With the possible proviso re: tyres and brake temps, it did seem likely that Hamilton would get Verstappen without stopping again. The theory that he was struggling to get past is severely undermined by the fact that Verstappen was getting very lucky repeatedly picking up DRS from back markers, which was clearly not going to endure indefinitely.
Anyway, back to the more “serious” point - what to look out for next? Hamilton’s gear box restricting him to fifth gear? A late parc ferme change necessitating starting from the pit lane?
After the first pit stops, Verstappen had a 5 second or so lead over Hamilton (after Hamilton stayed out longer on his used tyres). Over 2 laps or so, he cut Verstappen's lead right down to under 1 second (off-camera because the TV coverage sucked). It was a crazy pace difference which made me think Verstappen had a problem. Once he was behind him, he began stagnating again & made one small attempt to pass before sitting back (until his second stop & the result we saw).
I did think that massive Mercedes pace advantage after the first stop was "strange". So you're not the only one who's contemplated the notion their car is massively better than everyone else's. But to counter that I could point out that Bottas was terrible, but so was Gasly (in the other Red Bull), ergo a claim would also be made that both cars between teammates aren't exactly equal considering the real number one status of the guys in front.
Whatever it was, it was a good race. Vettel also managed to chase down 19 seconds on Leclerc over 30 laps, so Hamilton's exploit wasn't totally unusual on Sunday because the conditions were there for that sort of tyre advantage.
