Ethan Sparks got the better of Ryan Frost to take the first BTC race win of the day, as points leader Filip Surowiak was third.
In typical BTC style, it was a close race from start to finish, with both Sparks and Frost taking it in turns to lead throughout the 14 laps.
Sparks led into the final lap and despite having both Frost and Surowiak nipping at his heels, was able to get great drive out of the Loop to finish the 0.332 clear of Frost, with Surowiak a further 0.217s behind in third.
Harrison Mackay took fourth as Peter Willis rounded out the top five.
