Formula 1's final Sprint weekend of the season starts Friday at Singapore's Marina Bay Street Circuit. Practice and Sprint qualifying are Friday, Oct. 9. The Sprint and Grand Prix qualifying are Saturday, and the race is Sunday, Oct. 11, at 8 p.m. local time, which is 8 a.m. ET, Formula1.com said.

George Russell won here last year from pole. This time, he will start the Grand Prix from the back of the grid. His engine failed near the end of the Bahrain Grand Prix, held in Malaysia, and Mercedes had to bring a new one forward. That pushes him over the season limit, and the penalty applies only to Sunday's race, not Saturday's Sprint.

"That is particularly frustrating given the way he drove last weekend," team principal Toto Wolff said.

The standings are lopsided. Kimi Antonelli has 320 points, Russell 236 and Lewis Hamilton 214, Yahoo Sports reported. Even a perfect weekend for Antonelli, winning both the Sprint and the race, would leave Russell with a path to the title. The first chance for Antonelli to clinch is the U.S. Grand Prix in Austin on Oct. 25.

Singapore is also the last round where a driver can score more than 25 points in one weekend, because of the Sprint. That makes it a big chance for the leader to stretch his lead.

Others have a shot at the win. Max Verstappen has never won in Singapore, but he won in Malaysia a week ago. Ferrari showed speed with a recovery drive at Sepang, while McLaren admitted it lacked pace.

The track is tough. It is a long street circuit with close walls and bumps, and drivers can lose up to 3 kilograms during the hot night race. A safety car has come out in about two of every three recent races here. Pirelli expects most teams to try a one-stop strategy.

Sebastian Vettel holds the record with five Singapore wins. Hamilton set the lap record last year.

What we know: Russell starts Sunday's race last, and Antonelli cannot clinch this weekend.
What we don't: How far Russell can climb on a track where passing is hard.
