Valtteri Bottas ended his yearlong drought with a dominant victory in Turkey on Sunday while unhappy Mercedes teammate Lewis Hamilton finished fifth and lost the F1 championship lead to Red Bull's Max Verstappen.

Verstappen, 24, was runner-up and 14.584 seconds behind the Finn at a wet Istanbul Park to overturn a two-point deficit to Hamilton and go six points clear with six races remaining.

Red Bull teammate Sergio Perez finished third with Ferrari's Charles Leclerc fourth and ahead of seven-time world champion Hamilton, who had started 11th due to an engine penalty.

"It's been a while but feels good. I think from my side probably one of the best races I've had ever," said Bottas, who started on pole position and took a bonus point for fastest lap.

"Apart from that one little slide, everything was under control."

The victory, sealed by overtaking Leclerc 11 laps from the end after the Ferrari driver had taken the lead by staying out while others pitted, was the Finn's first since Russia in September last year and 10th of his career.

Verstappen, who started on the front row, had a quiet race and said it had all been about tire management.

Hamilton might have been on the podium, but Mercedes called him in for a late stop from third place for a fresh set of intermediate tires with the track drying.

"Why did we give up that place? We shouldn't have come in, man. Massive (tire) graining. I told you," said the angry Briton in heated radio exchanges as he realized he had lost two places in the pits.

He noted afterward that Alpine driver Esteban Ocon, who finished 10th, had made his one set of tires last the entire race.
