With his DNF in Baku, the soonest Piastri could clinch the title would be in the Brazil Sprint. This would require Norris score no more than 8 points and Verstappen score no more than 52 points between now and the end of the sprint. If Piastri wins every race (GP and Sprint), he would clinch in Vegas, even if Norris comes 2nd in everything. Consequently, if Verstappen wins every race and Piastri comes 2nd in all, then Piastri would win in Abu Dhabi by 18 points. With a maximum of 43 points on offer, this is guaranteed to happen provided they score at least 13 points.
