Horsham harness racing horseman Aaron Dunn is eyeing a second Group 1 success with his star Bondi Lockdown after the colt produced a monstrous display to win his semi-final at Melton on Wednesday night.

No locking down Bondi 1 — **Bondi Lockdown winning a Vicbred Super Series semi-final.**

Dunn sent the VHRC Caduceus Classic winner from January around the field down the back straight, and despite appearing to be beaten off by favourite and leader Beyond Delight (Emma Stewart/Greg Sugars), came again in the home straight and pulled away to score by nearly 4m.

The field rated a sizzling 1:53.5 for the 2240m trip, with Beyond Delight second and Captain Bellasario (Jayne Davies/Jack Laugher) third.

“He broke the track record at home by two seconds the other day and pulled up with a heart rate of 77 so that sort of gave me confidence that he was on song,” Dunn said after the race.

Bondi Lockdown, a son of Somebeachsomewhere who has now won 11 of 25 career starts, was one of eight runners from the Dunn stable to compete at Melton on Wednesday night.

Rebecca Bartley teamed up with Emma Stewart’s Tasmanian import Longfellow to win the other of the semi-final battles.

From barrier two, Bartley worked to the front in the early stages of the race and got away with a controlled 30.8 third quarter before dashing home in 26.7.

Kimble (Matthew Craven/Sofia Arvidsson) was a neck away in second, with Better Eclipse (Jess Tubbs/Greg Sugars) in third.
