Vesti arrived at the Yas Marina Circuit with a 25-point deficit to championship leader Theo Pourchaire, meaning he had to score at least two more points than the ART driver on Saturday to take the matter to Sunday.
This ambition was comfortably achieved with a brilliant fightback display after dropping from first to fourth on the opening lap, before recovering to the front in the closing stages, taking the chequered flag with a margin of 3.8 seconds.
