Formula One: Sergey Sirotkin to join Lance Stroll in Williams for 2018 season, Robert Kubica to be test driver
Sirotkin replaces Brazilian veteran Felipe Massa, who retired at the end of last year
London: Russian rookie Sergey Sirotkin will race for Williams this season after being chosen ahead of Polish rival Robert Kubica in a multi-year deal.
The Formula One team made the long-awaited announcement with a statement on Tuesday, filling the last remaining vacancy on the starting grid for the season starting in Australia on 25 March.
The 22-year-old will partner 19-year-old Canadian Lance Stroll, who made his debut with the former world champions last year.
Sirotkin replaces Brazilian veteran Felipe Massa, who retired at the end of last year.
“It took a huge amount of work to get where I am, and I’m really happy and thankful to everyone involved,” said Sirotkin, who was previously on Renault’s books as a development driver.
“The result of our combined efforts has helped me achieve my dream, and rest assured the team can rely on me to deliver my best.”
Sirotkin has been backed by Russian billionaire Boris Rotenberg on his way to the top.
Deputy team principal Claire Williams said the team had taken their time to evaluate all options but were confident the new pairing would deliver.
“The Williams philosophy has always been to promote and develop young talent and Sergey fits right into that ethos,” she said.
“Lance has had a record-breaking debut season, and with a year now under his belt, he will be ready to hit the ground running in 2018.”
Kubica, 33, had been hoping to return to a Formula One race seat for the first time since a 2011 rally accident partially severed his right arm.
He and Sirotkin both tested with Williams after last year’s season-ending Abu Dhabi Grand Prix.
Kubica will be the team’s test and development driver.
Bottas, who has been with the team since 2017, has yet to finish a race this season ahead of either teammate and world champion Lewis Hamilton or Red Bull's Max Verstappen.
The Mercedes driver started from second on the grid behind teammate Valtteri Bottas, who finished third behind Verstappen's Red Bull and took a bonus point for the fastest lap.
It was the fourth successive Saturday that the Japanese rookie had been out-paced by the more experienced Frenchman.
