Jack Hawksworth concluded the Canadian leg of his 2012 Star Mazda Championship campaign with undoubtedly his most dominant success of the season so far, meaning the US racing rookie will head into the final five encounters with a healthy 41-point lead in the standings.

Having left his rivals eating his dust with a magnificent victory double in Toronto and chalked up win No 5 a fortnight later in Edmonton, Cullingworth’s Hawksworth went to Québec for the Grand Prix de Trois-Rivières.

He was easily quickest in claiming pole position on what he called “an awesome street circuit”, breaking the lap record in his Team Pelfrey single-seater.

Then the 21-year-old British Racing Drivers’ Club (BRDC) Rising Star dominated race one, winning it by a staggering 24 seconds.

In race two, Hawksworth was ten seconds ahead before a torrential downpour led him to err and crash out. He broke his front wing and bent the suspension.
