SAO PAULO (AP) Racing around a wet track, Nico Rosberg was fastest in the final practice Saturday ahead of qualifying for the Brazilian Grand Prix.

Wet weather – or at least spotty showers – is expected for Sunday's race in which Rosberg could claim his first drivers' title.

Rosberg is the Formula One season champion if he wins in Brazil on Sunday. He can also finish second in Brazil, and third in two weeks in Abu Dhabi, and still be the champion.

If Mercedes rival Lewis Hamilton wins, the season title can only be decided in Abu Dhabi. Hamilton cannot claim it in Brazil.

Rosberg was 0.093 seconds ahead of Hamilton. He was slower than Hamilton in both practice sessions on Friday on a dry track.

The hilly Sao Paulo circuit has a history of upsets, particularly when it rains.
