Wet wins for Marquez and Vinales
Marc Marquez and Maverick Vinales mastered wet conditions in Assen to win the Moto2 and 125cc Moto GP races.
Marquez wrapped up the second win of his Moto2 career in wet conditions at Assen, and moved up to second in the championship in the process.
Series leader and polesitter Stefan Bradl crashed out near the end of the race, but remains 57 points ahead of Marquez in the standings.
Bradl (Kiefer Kalex) struggled from the outset in the wet race, steadily slipping down the order from pole and falling as low as 13th. He managed to get back up to eighth before sliding out at the chicane in the closing stages.
Simone Corsi, Bradley Smith and Marquez (pictured) set the early pace, although as conditions improved slightly Corsi would begin to fade, eventually tumbling right back to 14th.
Kenan Sofuoglu then moved up to join Smith and Marquez's lead battle, with Yuki Takahashi shadowing them. All of the first three took turns in front amid some very close racing on the greasy track.
Takahashi picked his way through to second, only to crash on lap 20 of 24. Marquez was leading at that stage, and the accident gave him a little breathing space, as he inched away to win by 2.3 seconds over Sofuoglu - the Technomag-CIP rider securing his first Moto2 podium. Smith fell back from Sofuoglu as he claimed a second straight top-three finish in third.
Anthony West showed his usual outstanding wet weather form to come through from 21st to fourth on the MZ, a short distance ahead of the battling Alex de Angelis and Mattia Pasini.
Vinales scored the second win of his 125cc career in a rain-truncated race at Assen, which championship leader Nico Terol had to sit out due to hand injuries sustained on Saturday.
Aspar rider Terol was unable to take up his eighth place on the grid as he required surgery after crashing in both morning practice and qualifying yesterday, giving his rivals a golden opportunity to carve a chunk from the hitherto dominant Spaniard's points lead.
Although the race was declared officially dry, drizzle began falling from the early stages. That led to an astounding lead battle in the slightly slippery conditions, with up to eight bikes vying for first place and racing four and five abreast into the corners as they scrabbled for whatever grip was available on the damper parts of the circuit.
Polesitter Vinales kept a relatively low profile amid this initial madness, falling to ninth while the likes of Efren Vazquez, Sandro Cortese, Sergio Gadea and Luis Salom disputed the lead.
But as the race progressed and the weather got worse, Vinales picked his way forward and got back in front.
Then as the rain increased and riders behind began frantically waving for the race to be stopped, Vinales simply got his head down and pushed harder, breaking away from the field. When the red flags were put out on lap 14 - late enough in the distance to avoid the need for a restart - the young Spaniard was nearly three seconds clear and duly claimed victory.
The hard-charging Salom secured his maiden podium in second plae, with Vinales' team-mate Gadea making it an all-Spanish rostrum, just ahead of Ajo team-mates Johann Zarco and Danny Kent. Vazquez and Jonas Folger, who were also major factors in the early lead dice, finished seventh and eighth.
Local favourite Jasper Iwema flew through the order from 33rd on the grid, getting up to 17th before tangling with Adrian Martin. He rejoined but retired in a second accident.
