Supercars ace Jamie Whincup fears a Saturday shocker at Queensland Raceway has undone months of hard graft by his Red Bull Racing team.
The Holden star finished a forgettable 20th in the 120km event opener at Ipswich, a result compounded by championship rival Scott McLaughlin storming to his sixth win of the season.
Whincup, starting the day just six points behind the DJR Team Penske driver, is 111 points adrift of the the New Zealander. He knows the ground he had made up earlier this month with his first win of the year in Townsville has been instantly gifted back.
