Six weeks ago Dexter Dunn had no show of reaching 200 winners this season, now 23 winners later, the task still looks tall but not completely futile.

Dunn, 22, who already has four harness driving premiership titles to his name and his fifth in the bag, now has the lure of a third double century. Mathematically the equation is tough.

He's got just under three weeks in which to drive 21 winners and if he sticks to the South Island he has just six meetings in which to do it.

He will make a rare appearance in Cambridge tonight to drive Bit Of A Legend and Chanelle Bromac in heats of the Australasian Breeders Crown.

The rich series could become a happy hunting ground. Often restricted to less than four runners and officially recognised as non-tote events, the heats count toward the premiership and Dunn has drives in six this weekend.

On ability he should win half if not more. Bit Of A Legend, Texican and Onlyforyou, who are in action in Canterbury, should win their heats.

With the bonus of quality drives at both Addington tomorrow night and then again at Rangiora on Sunday – come Monday morning "Double D" could be ahead of schedule. Whether or not he can reach the 200 winners by the end of racing on July 29 remains to be seen.

But Dunn can reflect on what has been another brilliant season in the sulky.

He missed the first month of the season but quickly set into his stride picking up his first 50 winners by the middle of November with Cran Dalgety setting the wheels in motion.

Dunn has driven 72 winners for the Kentuckianna Lodge stable this season, the most profitable of those being Texican who he has combined with for nine wins.

Bettor's Fire (8), Donegal Delight (6) and Bettor's Creek (5) have also all been solid sustenance from the Dalgety barn. Southland pacer Scarrymcleary has served him well with five wins for the season, Southern Sun gave him four and Hone Heke, Castellina Lover and Jay Bee's Grin all chipped in with three.

Dunn is set to become the youngest driver to reach the 1000 win mark next season, surpassing Mark Jones who achieved the feat when he was just 25.
