Mercedes driver Nico Rosberg set the quickest time during the second practice session for the Mexican Grand Prix.
Rosberg posted a time of 1:21.531 on his second flying lap on Option tyres to finish 0.245s clear of Red Bull driver Daniil Kvyat.
Daniel Ricciardo was a tenth adrift of his team-mate in third position, with Lewis Hamilton suffering a spin at Turn 4 en-route to fourth spot.
Ferrari collected fifth and sixth courtesy of Sebastian Vettel and Kimi Räikkönen, the German driver narrowly behind Hamilton but 0.4s clear of the Finn.
Valtteri Bottas suffered a wild moment under braking for Turn 1, losing control of his Williams FW37 and wiping the front wing from the car.
He was able to return to the pits for repairs and re-join the action to finish the session in seventh position.
McLaren demonstrated improved pace as Fernando Alonso went eighth quickest, while Jenson Button emerged from the garage late on and finished a tenth of a second behind in ninth.
Felipe Massa was 10th for Williams, ahead of Force India’s Nico Hülkenberg.
Pastor Maldonado was 12th for Lotus, eclipsing Carlos Sainz Jr. by a thousandth of a second.
Felipe Nasr beat Sergio Pérez to 14th position while Romain Grosjean stopped on track with a gearbox problem.
Grosjean's stoppage brought out the red flags while marshals recovered his stricken Lotus E23 Hybrid.
Marcus Ericsson was a lonely 17th for Sauber, ahead of Alexander Rossi and Will Stevens.
Practice one pace setter Max Verstappen brought out the red flags within the first five minutes of the session as he crashed exiting the stadium section.
Light rain fell during some stages of the session and intensified in the final 10 minutes, sending the drivers back into the pits, with some re-emerging for a couple of laps on Intermediate rubber.
