Moments after he recaptured the lead of the championship from Valtteri Bottas following his fine victory at the Circuit de Catalunya, an emotional Hamilton dedicated his triumph to Harry Shaw - a five-year-old who has been diagnosed with a rare form of cancer.
And after his win Harry posted a message of congratulations. I'm very proud of everyone back at the factory and thankful for all their hard work.
The fight came down to the final runs, but neither driver was able to improve the second time around, confirming Bottas's dominating 0.634-second margin and his third successive pole of the season.
"You're not the first one to ask me that question, but I'm in an awkward position. actually, I'm not in an awkward position".
In a season everyone hoped would produce battle after battle, increasingly it seems that Verstappen and Red Bull are the only forces with the potential to inject the drama we're all hoping for. Leclerc eventually found himself a sitting duck, with Vettel moving past him on the 37th lap of the race.
The safety auto bunched up the field again, creating some much-needed tension but Hamilton had everything under control at the re-start.
Mercedes team boss Toto Wolff thinks that an explanation for the turnaround in form from testing to now may be explained by how the higher downforce concept allows room for more development without upsetting the vehicle balance.
Vettel damaged his on the opening lap and both drivers also lost time in the pits with a wheel nut cross-threading problem. "Of course we want to be as quick as we can be, we don't know why the others have fallen off a little bit", Hamilton told reporters after Sunday's race.
"We are losing a lot in each corner, not only in the last sector, it is each single corner we are slow", said Binotto.
The safety vehicle was deployed after McLaren's Lando Norris and Racing Point's Lance Stroll tangled at the first corner and ended up stranded in the gravel.
Here are the key talking points from another incident-packed weekend of Formula One racing.
Pierre Gasly was a solid sixth in the second Red Bull ahead of Kevin Magnussen of Haas, home hero Carlos Sainz of McLaren, Daniil Kvyat of Toro Rosso and Romain Grosjean in the second Haas.
