Star New Zealand reinsman Dexter Dunn has continued his sensational Trans Tasman form at Tabcorp Park Melton tonight.

In what has been a sensational week, Dunn has captured the World Drivers’ Championship at Menangle, journeyed home to secure the Auckland Cup before crossing back to Australia for tonight’s meeting.

As for his latest triumph, Dunn combined with the Kevin Townley-trained Sheemon to score an upset victory in one of the program’s Group Ones.

The feature also doubles as a heat of the Great Southern Star, with the $300,000 Final scheduled for 10pm tonight Victorian time.

After leading from the pole, Sheemon was eased to take the trail behind defending champion Keystone Del in what proved a winning move.

Angled into the clear at the top of the home straight, the daughter of Monarchy sprinted to a three-metre win from Keystone Del, with Brunelleschi a metre away third.

“I’m very happy with that run,” Townley said. “She got to the line well and was driven perfectly by Dexter.

“Now we just have to see how she handles racing again later tonight.

“She’s come off the track in pretty good order and hasn’t been knocked around, so I don’t see it being a problem.”
