"And then the guys (mechanics) have to reshuffle and I think that cost us a bit of time".
Hamilton conceded that he will head to the next round in Monaco with caution rather than in expectation following his poor display at the principality previous year, but the 64th win of his career will, for the first time this term, provide him with optimism that he can outdo Vettel in their tug of war for glory.
Max Verstappen, who ran into Williams' Sergey Sirotkin, took third with a broken left front-end plate for his first podium of the season. "That's a different ballgame again and a track where we've struggled in the past, so let's see".
While there was more than a hint of fortune about Hamilton's opening victory of his championship defence in Azerbaijan a fortnight ago, the Englishman was in a class of his own on Sunday.
All three drivers were unhurt but it was an exceptionally unsafe incident and why Grosjean kept his foot on the gas as he span, causing smoke that unsighted the following drivers, seems inexplicable.
Beating Hamilton was never on the cards but Bottas fought hard, overcoming tyre wear (on the medium compounds) to defend track position from Max Verstappen who was breathing on the tail in the final laps.
He did not look able to threaten Hamilton however, with Mercedes optimistic that they are getting to grips wth the issue of the tyre operating window.
Sebastian Vettel's strategy of making a second pit stop under a Virtual Safety Car period failed to come to fruition, as he dropped from second to fourth. With a damaged wing towards the end of the race, the 20-year-old showed superb composure to match the same lap times as Ricciardo and drive faster than Vettel.
"I was trying to go for every sector record", he laughed. Daniel Ricciardo (Red Bull) + 50.058; 6.
When Vettel made his second stop during a late virtual safety vehicle period, after Esteban Ocon parked up his Force India by the side of the track, it backfired and he lost a place instead of gaining anything. The 37-year-old was sitting behind Hamilton in second on lap 26 when he experienced trouble with the auto and was subsequently overtaken by both Red Bull drivers and fell into 17th. Potentially they may have believed with their first stop so early they could not make the flag with only one stop.
After a tough start to his season, Verstappen surely heaved a sigh of relief with his podium finish in Spain.
