READ NOWThe next two heats were more clear-cut, as Stuart’s big guns fired their way to huge wins, with both Quartz Bale and Tureaud exhibiting their limitless potential.
Quartz Bale maintained the unbeaten start to his career in the second heat.
The 38kg behemoth monstered his rivals by jumping straight to front and leaving them in the dust, in a sizzling personal best run of 30.17.
Now 8-0 Quartz Bale, already the 405m track recordholder at Mandurah, is likely to be the favourite in the final, despite starting from wide on the grid.
Tureaud made a good return from two and a half months on the sidelines with an impressive victory in the final heat.
The dog showed no ill-effects from the shoulder injury that had been keeping him off the scene.
