Dutchman Richard Verschoor has won the opening race at the Hampton Downs round of the Toyota Racing Series on Saturday.
Championship leader Marcus Armstrong made a strong start from third to get right on Verschoor's tail and followed him for the duration of the race. He made a brief attack towards the end of the race but eventually the Kiwi settled for second.
"That was a good race," the 17-year-old said. "If I wanted to attack I could have. The last five laps it was necessary for me to back off because the water temp was high.
"I am happy with second.
"In my opinion I could have won that race today but it would have come at the risk of the engine."
