Marc Marquez remained the man to beat in Saturday morning practice for the MotoGP title showdown at Valencia.
The championship leader registered the fastest ever lap at Valencia with a 1m30.803s towards the end of the session - 0.113 seconds quicker than title rival Jorge Lorenzo.
Marquez remained under the radar for most of the session while putting in a few long runs in an attempt to acclimatise to the softer rear tyres in the relatively cool conditions.
He produced his stunning lap with less than three minutes of the session remaining, demoting Honda team-mate Dani Pedrosa, who had topped the timesheets for the majority of the morning, in the process.
Title contender Lorenzo made steady improvements and looked poised to match Marquez's time, but was unable to maintain the pace through all four sectors of the lap.
Lorenzo's Yamaha team-mate Valentino Rossi emerged third quickest, ahead of Pedrosa and Cal Crutchlow. The latter was suffering from a temperamental brake lever issue mid-session.
Alvaro Bautista and Stefan Bradl took turns in sixth place and the momentum finally swung in the Spaniard's favour, while the Ducatis of Nicky Hayden and Andrea Dovizioso ended up eighth and ninth respectively.
The top 10 was rounded out by Tech 3's Bradley Smith, while Aleix Espargaro took fastest CRT honours in 11th.
