Whelan was unable to use her allowance in the non-claiming race on Borrack, who carried 68kg under the highweight conditions but she judged the race perfectly to score her first win in four rides on the 7-year-old.
The winner of four of his five runs this campaign in New Zealand, the hurdler started at $8 and underlined his versatility winning by 1 lengths from Crafty Cruiser ($4.20) and favourite Brungle Cry ($2.15).
Whelan also had a past association with Baron Douro, who was trained by Myers before Payne bought him as an unraced 2-year-old.
"Lisa actually trialled him in New Zealand before we bought him so I thought they would suit each other," Payne said.
Whelan feared she may have erred getting back so far on Baron Douro ($15) but with her allowance and racing in blinkers for the first time he was up to the task, powering away to 2-length victory over Vee Force ($9) and Daybreak ($17).
"I thought I may have been a little bit too far back but Patrick said to let him settle and it worked out."
While in Victoria, she is also helping to look after several Myers-trained horses who are based at Payne's Plumpton stables.AAP
