Vinales tops Friday practice at Assen
After two weekends ruled by one man, the timesheets have had a shake up once again at the Motul TT Assen – with Maverick Vinales (Movistar Yamaha MotoGP) taking to the top late in FP2 to go fastest on Friday, 0.121 seconds ahead of Andrea Iannone (Team Suzuki Ecstar). After reigning Champion and Championship leader Marc Marquez (Repsol Honda Team) went quickest in FP1, it was all change in the afternoon as the number 93 was eighth fastest.
Under sunny – and scorching – skies at the TT Circuit Assen, the two men who fought for the 2017 win dueled it out for third, with Danilo Petrucci (Alma Pramac Racing) just 0.015 ahead of compatriot Valentino Rossi (Movistar Yamaha MotoGP) by the end of action. ‘Petrux’ was also top Independent Team rider on Day 1 on his Ducati, with fastest Honda and fellow Independent Team rider Cal Crutchlow (LCR Honda Castrol) locking out the top five.
After the swing of momentum of late in the Ducati Team, Andrea Dovizioso will be happy to have edged out teammate Jorge Lorenzo on the combined timesheets, with ‘DesmoDovi’ taking P6 and Lorenzo just behind in P7 – despite a rare crash for the ‘Spartan’ sustained in FP1. The two were split by almost nothing, with a difference of only 0.011 and both just ahead of Marquez in eighth. Marquez also suffered a few moments and twitches in FP2 but no crash, not focusing on a fast lap.
