Nico Rosberg and Lewis Hamilton had the fastest laps as Mercedes dominated the first practice for Formula One's Austrian Grand Prix on Friday.
Rosberg's best time on the 4.3-kilometer Red Bull Ring was 1 minute, 11.295 seconds, beating teammate Hamilton's fastest lap by 0.140.
Ferrari's Fernando Alonso trailed by 0.311 in third.

Four-time champion Sebastian Vettel escaped damage to his Red Bull car as he came off the track in the final turn and spun twice on the grass before ending up on the track again.
Vettel's teammate Daniel Ricciardo also spun on the same spot shortly afterward.
Rosberg leads Hamilton in the drivers' standings by 140-118 points going into Sunday's race, the first GP in Austria since 2003.
