With a full 50-points loot for two third place finishes over the weekend, Daruvala rises to 147 points, 12 ahead of his Dutch rival with one round left in the Championship.
The two worst results for each driver will be dropped, meaning the gap between the two remains small: all is set for a grand finale showdown in Genk (Belgium) on October 3-5.
The fourth round of the calendar, running on the track that saw Formula One World Champions Michael Schumacher and Sebastian Vettel hone their skills as young drivers, marked an excellent weekend for the Indian racer, who was quick from the get-go, qualifying third in a very competitive field of 32 drivers.
The Force India Academy driver's recovery drive was even more aggressive in the second race of the weekend, when he had to claw his way from 10th after the first corner to claim another third spot at the line. This was crucial as it guaranteed the Indian a good position on the grid for the first final - third and on the ideal side of the track.

A fierce, but clean, fight ensued, with the two Championship protagonists exchanging positions several times; finally, with three laps to go in the 23-rounds race, claimed the lead and took good defensive lines to hold back his rival until the chequered flag.
Final 2 promised to be another tight battle between the two drivers, but fate had other plans. With most of the field, unlike Daruvala, on fresh tyres, the race appeared to be very close for the top seven; on lap three, as the Mumbai boy was leading and van Leeuwen was trailing in third place, the Dutchman's kart ground to a halt.
