Polesitter Razgatlioglu was attempting to retake the lead he had lost to Bautista when he went down under braking for Turn 9, suffering a costly crash during an important stage of the championship.
Bautista was able to capitalise on the uncharacteristic error from his Yamaha rival to stretch out a massive 80-point lead in the standings, the biggest it has been all year, to boost his chances of winning the title.
