Holden teammates Jamie Whincup and Craig Lowndes sealed a three-race cleansweep of the V8 Supercars round in Perth yesterday.
A day after Lowndes bagged a record-breaking 91st career victory, his Red Bull Racing partner was victorious in both 100km battles at Barbagallo Raceway.
Whincup grabbed the lead from Lowndes in the final race of the weekend with an opportunistic move on lap 32 of the 42-lap showdown.
As soon as the race re-started following the second safety car deployment, four-time series champion Whincup swooped to hit the lead and hold off his 39-year-old teammate by a comfortable margin of 1.57sec.
In the process, Whincup won the overall round with a second-placing to Lowndes on Saturday and extended his championship lead over Ford's Will Davison to 65 points.
Jason Bright was third in another solid performance followed by Davison, David Reynolds and New Zealand pair Shane van Gisbergen and Fabian Coulthard.
Whincup started on pole, but relinquished the lead on lap 16 when he and luckless Ford driver Mark Winterbottom ploughed through the sand on the final turn after slipping on engine coolant spat out from the Mercedes of Maro Engel.
Lowndes sped past and despite being well set for another triumph, was then outwitted by Whincup.
Earlier, Whincup claimed a comfortable victory in the second race when he took the chequered flag by a margin of 0.75sec over fellow Holden driver Bright and Winterbottom.
