Relentless Me, a two-year-old filly by Restrepo, hoisted a new lifetime mark of 1:55.1 winning at the Maryborough Cup meeting on Sunday (October 17).
Starting from the No 6 gate, the filly pinged straight to the front and maintained a solid tempo throughout.
He zipped home in 56 seconds to score by 14.4 metres.
It was her second success.
Relentless Me is out of the Presidential Ball mare Ballygeana, who has left three sub 2:00 winners from as many foals.
Restrepo, who is standing at Goodtime Lodge, has sired eight winners from nine starters to date.
