Valtteri Bottas was caught in second place in the fifth World Championship of the season, but only a couple of laps before the goal Lewis Hamilton easily got past the Finnish driver with clearly fresher tires.

Mercedes team manager Toto Wolff revealed why Hamilton did his second tire change up to a dozen laps later than Bottas.

Unknowingly, Bottas helped Hamilton, whose tactics were changed.

- When we got Valtter's tires in, we saw that there was still a lot of rubber left, so that's why we extended Lewis' "stint", team manager Wolff told

- Eventually Lewis passed Valtter. It is clear that Valtteri is not happy, and I fully respect that. None of us are happy with this result, Wolff said.

Had Hamilton been caught in the depot clearly earlier, he would have had a much worse chance of overtaking Bottas. Then there would not have been such a big difference in the tires.

Hamilton is now leading the World Championships by 30 points to Max Verstappen, who grabbed his season-opening victory in England. Bottas is third, 34 points from Hamilton.
