SPIELBERG, Austria (AP) — Red Bull's hopes for a triumph on its home circuit were dampened Friday as Mercedes regained its dominance in Formula One, clearly setting the pace on the opening day of practice for the Austrian Grand Prix.
With Daniel Ricciardo's maiden victory in Canada two weeks ago, Red Bull ended a six-race winning streak by Mercedes but the Australian driver and his teammate Sebastian Vettel did not come close to matching their rival's speed on the Red Bull Ring.
Lewis Hamilton beat teammate Nico Rosberg to the fastest time in the second practice. Hamilton completed his best lap on the 4.3-kilometer (2.7-mile) track in 1 minute, 9.542 seconds, topping Rosberg by 0.377. Ferrari's Fernando Alonso was almost a second off the lead in third.
Vettel came sixth, more than 1.4 seconds behind Hamilton, while Ricciardo posted the eighth fastest time.
Mercedes also came 1-2 in the opening practice, with Rosberg beating Hamilton by 0.140.
"It's so close between the two of us," Rosberg said about the fight with Hamilton for pole position. "I'm hoping we will still have the edge on everybody else. That seems to be the case today."
However, Hamilton said he wouldn't mind if Rosberg started in front of him on Sunday.
"Hunting definitely brings out the better side," the 2008 F1 champion said. "When you are in front, you feel vulnerable and any mistake you make you are going to be caught."
In the morning session, Ricciardo and Vettel came only 13th and 15th respectively.
"We clearly did better in the afternoon," Vettel said. "We are not there where we want to be when it comes to speed ... but it will be warmer on Saturday and Sunday and I think that will bring us closer."
In the first session, Vettel brought his car back to the garage undamaged following a spectacular incident in the final turn. He came off the track and spun twice on the grass before the car came to a standstill on the track again.
"That wasn't planned of course," the four-time champion said. "I went too wide and the wet grass was slippery."
