Sebastian Vettel led a Ferrari one-two in final practice for the Singapore Grand Prix as Lewis Hamilton finished third.
Vettel, who trails Hamilton by 30 points in the Formula One World Championship, lost valuable track time on Friday after he collided with the wall.
But the German set the pace ahead of qualifying with a track record of the Marina Bay Street Circuit.
Vettel finished 0.362 seconds clear of team-mate Kimi Raikkonen, while Hamilton was more than half-a-second adrift.
Valtteri Bottas finished fourth in the sister Mercedes, 0.549sec down on Vettel.
Hamilton trailed Raikkonen by just 0.011sec here on Friday but – on the evidence of Saturday’s final running – the defending champion may have his work cut out to stop the Ferraris in the shoot-out for pole position.
The Red Bull duo of Daniel Ricciardo and Max Verstappen finished fifth and sixth respectively, more than one second off the pace of Vettel.
Verstappen complained about the Renault engine in his Red Bull during Friday’s practice session, and when asked for feedback from his team on Saturday, the Dutchman replied: “Feedback? The product in the back of this car is not working like I want it to.”
Red Bull are divorcing from Renault at the end of the season to be powered by Honda in 2019.
Elsewhere, Romain Grosjean was seventh for Haas, ahead of Force India’s Esteban Ocon and Sergio Perez. McLaren’s Fernando Alonso rounded out the top 10.
