Nico Rosberg bounced back from a brake issue in FP1 on Friday morning to top the second free practice session for the Mexican Grand Prix.
Rosberg posted a fastest lap time of 1:21.531 to finish in P1 ahead of Red Bull drivers Daniil Kvyat and Daniel Ricciardo at the Autodromo Hermanos Rodriguez as the entire field struggled to get to grips with the slippery track.
Max Verstappen was the first to fall foul of the green track, losing the backend of his Toro Rosso at the final corner and spinning into the wall, bringing his session to an end after just five minutes.
The session soon resumed after the stricken Toro Rosso had been recovered, but drivers still tested the limits of the grip on offer. Lewis Hamilton survived a spin, while Valtteri Bottas somehow kept his Williams out of the wall after losing control at over 200mph, damaging only his front wing.
The majority of the quick times came midway through the session, with Rosberg setting the pace to finish two-tenths of a second clear of Kvyat in second place. Ricciardo followed in third, with Mercedes’ Lewis Hamilton rounding out the top four.
The Ferrari duo of Sebastian Vettela and Kimi Raikkonen followed Hamilton home in P5 and P6, with Bottas recovering from his spin to finish seventh.
McLaren continued to show signs of improvement after an impressive outing in Austin by ending FP2 eighth and ninth, with Fernando Alonso leading teammate Jenson Button. Felipe Massa rounded out the top ten for Williams.
The on-track action continues in Mexico on Saturday with FP3 and qualifying. For full details on how to watch these sessions live with NBC Sports, click here.
