Red Bull's Max Verstappen found some pace to take the top spot during final practice for the Mexican Grand Prix after initially struggling for one-lap pace during Friday's running.
The Dutchman was a tenth quicker than the Mercedes of Lewis Hamilton in second, with the Briton posting a 1m19.231s to put him just over a tenth clear of the second Red Bull of Daniel Ricciardo.
The Red Bull duo look much closer in qualifying trim, although traffic didn't help Mercedes as both Hamilton and Nico Rosberg – almost half a second off Verstappen – struggled to make a clean lap.
Williams' Valtteri Bottas shot up to P5 ahead of the Ferrari who showed promise on Friday, but lacked pace in the higher temperatures.
Felipe Massa, Nico Hulkenberg and Carlos Sainz rounded out the top ten.
