Max Verstappen increased his lead by a further eight points in the world championship with a calculated and convincing victory ahead of Australian rookie Oscar Piastri in Saturday's rain-delayed sprint race at the Belgian Grand Prix. Red Bull's double defending world champion rode his luck when McLaren's Piastri snatched the lead by making an early pit-stop to switch from wet to intermediate tyres, to storm back and win by 6.6 seconds. Verstappen's win extended Red Bull's record this year to 14 wins from 14 races -- 11 grands prix and three sprints.
