US GP practice: Nico Rosberg fastest ahead of Daniel Ricciardo
Nico Rosberg set the pace in second practice for Formula 1’s United States Grand Prix, but Daniel Ricciardo resisted Lewis Hamilton and prevented a Mercedes one-two.
In a reversal of form from the morning session, championship leader Rosberg lapped nearly three tenths quicker than F1 title rival Hamilton during their qualifying simulations on the super-soft Pirelli tyre.
But Ricciardo sprang a surprise by splitting the pair with a 1m37.552s effort that placed his Red Bull within two tenths of a second of the leading Mercedes.
Sebastian Vettel was fourth fastest for Ferrari, over half a second adrift of Hamilton.
Max Verstappen was fifth in the second Red Bull, while Force India pair Nico Hulkenberg and Sergio Perez, and McLaren-Honda duo Jenson Button and Fernando Alonso, all lapped faster than Kimi Raikkonen’s Ferrari, which rounded out the top 10.
Raikkonen complained about the handling of the rear end of his Ferrari, and went off during his qualifying simulation, so had to rely on a second effort completed on the same set of tyres, which was only fractionally quicker than he managed on the soft compound early in the session.
Carlos Sainz Jr was the last man to lap below 1m39s, ending up 11th quickest in the underpowered Toro Rosso.
Kevin Magnussen and Felipe Nasr also impressed, lapping 12th and 13th quickest for Renault and Sauber respectively.
That put them clear of Williams pairing Valtteri Bottas and Felipe Massa, who were split by the second Toro Rosso of Daniil Kvyat.
Haas endured another difficult session at its home race, with Romain Grosjean only 18th fastest and team-mate Esteban Gutierrez 20th, behind Esteban Ocon’s Manor, which recovered well after an early spin into the gravel at Turn 17.
Grosjean complained that he could "barely drive the car", struggling particularly with the front end of his Haas.
Marcus Ericsson was 21st, over a second slower than team-mate Nasr, while Pascal Wehrlein ended up slowest of all runners, complaining of too much understeer in his Manor.
He returned to the track later and set improved times in the first and second sectors, but failed to complete the lap on each occasion so remained rooted to the bottom of the timesheet.
There was a brief red flag interruption just as the higher fuel long runs began, so marshals could clear some debris that fell from one of the Haas cars through the high-speed esses.
Gutierrez’s car appeared to shed more bits later on through the same section of the circuit, something that also occurred during a troubled morning session for the Haas team.

US GP: Lewis Hamilton leads Nico Rosberg in first practice
Lewis Hamilton edged Formula 1 title rival Nico Rosberg in first practice ahead of the United States Grand Prix as Mercedes started the weekend well clear of its rivals.
Hamilton finished 0.315s clear of Rosberg at Austin, posting a lap of 1m37.428s, with Red Bull’s Max Verstappen third quickest, but a further 1.6s adrift, albeit on the medium compound.
The leading times from Hamilton and Rosberg were set on Pirelli’s soft compound tyres, beating their early times on the super-soft as the track improved during the first 90 minutes of F1 running.
Ferrari’s Kimi Raikkonen set the early pace on soft tyres with a 1m42.738s before being deposed by Rosberg by 2.1s, with the championship leader the first to try the super-softs at the time.
Rosberg remained top for only a handful of minutes as Hamilton became the first to dip below the 1m40s mark with his first run on super-softs.
While Hamilton continued to lower the benchmark, just before the hour mark Rosberg then reclaimed top spot with a 1m37.743s on softs, but Hamilton produced a lap soon after that remained unbeaten.
Raikkonen finished fourth quickest, improving to a 1m39.407s ahead of Force India’s Nico Hulkenberg, who recently confirmed he is Renault bound in 2017.
Valtteri Bottas and Daniel Ricciardo were sixth and seventh best, the latter finishing 2.535s adrift on used mediums, with Sebastian Vettel down in seventh on softs.
At one stage Vettel ran wide at the penultimate corner, his Ferrari rattling over the rumble strips resulting in a piece of bodywork shaking loose, colliding with his right wing mirror in the process and dislodging it.
For the lap that followed Vettel drove with one hand as he used his left to stop the wing mirror from falling off.
Toro Rosso duo Carlos Sainz Jr and Daniil Kvyat completed the top 10, both 2.7s down and separated by just nine thousandths of a second on the super-soft compound, with the latter complaining of understeer.
On home soil for their team, Haas pair Romain Grosjean and Esteban Gutierrez finished 14th and 15th, 3.5s off the pace.
Their session ended in unusual fashion as both had to be wheeled back into the garage from the end of the pitlane where they had come to a stop.
There was an outing for two reserve drivers, with Force India’s Alfonso Celis Jr – in for Sergio Perez – four seconds down in 17th.
Manor’s Jordan King, in his maiden practice outing and replacing Pascal Wehrlein, was 20th, 4.584s adrift.
|3||Max Verstappen||Red Bull/Renault||1m39.379s||1.951s||28|
|5||Nico Hulkenberg||Force India/Mercedes||1m39.712s||2.284s||27|
|7||Daniel Ricciardo||Red Bull/Renault||1m39.963s||2.535s||26|
|9||Daniil Kvyat||Toro Rosso/Ferrari||1m40.131s||2.703s||16|
|10||Carlos Sainz||Toro Rosso/Ferrari||1m40.140s||2.712s||26|
|17||Alfonso Celis||Force India/Mercedes||1m41.422s||3.994s||27|
