"Pecco" Bagnaia led from the start after qualifying in pole position earlier on Saturday and gave a faultless performance in near perfect conditions on the legendary Dutch track.

Spanish daredevil rider Vinales continued a good weekend in third on an Aprilia, while Bagnaia's factory Ducati team mate Enea Bastianini maintained fourth.

Fabio Di Giannantonio on a Ducati VR-46 machine came fifth after having to ride a double qualifier on Saturday morning.

Behind him was South Africa's Brad Binder in sixth on a KTM, followed by Alex Marquez on a Gresini Ducati and Fabio Quartararo on an Yamaha.

The top 10 is completed by Prima Pramac Ducati's Franco Morbidelli and Portugal's Miguel Oliveira on a Trackhouse Aprilia machine.

Ducati-rider Bagnaia has steadily eaten into Martin's once sizeable lead and trails by just 15 points -- Spanish legend Marc Marquez crashed in the second lap remains third overall.
