Sebastian Vettel could finish only fourth as the Mercedes driver extended his Formula One lead to 17 points, though he and his team chief, Toto Wolff, warned they would not expect to enjoy such superiority at the next grand prix in Monaco.
Bottas' late retirement in Baku handed Hamilton his first win of the season on a plate - a result that edged him ahead of Vettel in the drivers' standings for the first time this term - and he followed that up with Sunday's impressive performance.
"On top of that, we had different tyres, which maybe suited others more than us".
Lewis back on top... but for how much longer? Since the first race at the Circuit de Catalunya in 1991, 25 out of the 28 races have been won from the front row.More news: Soros Foundation Leaves Hungary Citing 'Repression' of Civil Society
"I have an issue", he said on the radio with his characteristic understatement and matter-offact existentialism, and it was a technical concern that Ferrari could not diagnose.

Earlier in the season, it seemed that Wolff had ruled out the six-time grand prix victor for next season. "The bottom line is that we were not quick enough and that needs to be addressed", added the 30-year-old.

On lap 20, Valtteri Bottas entered the pits and also made the switch to medium tires. The Finn, however, has responded strongly to that reproval. Not did we have a disadvantage here, was that the case, was this the case, did the safety auto help or not? We have been here before. "I feel that if you understand something is getting wrong you should try to find a solution".
"I think it's just how you feel towards each other and there is no reason why we shouldn't be racing with each other for a few more years". He has zero points in 2018. Kevin Magnussen in the Haas finished in P6 behind Ricciardo. If not off to Ferrari in 2019, Haas might be eager to have the young star in their auto instead of an underperforming Grosjean.
