After terrorising the All Stars for the last couple of seasons John Dunn will join them for the $500,000 Pacing Final this Saturday.

Dunn has been the surprise call-up to partner Ashley Locaz for trainers Mark Purdon and Natalie Rasmussen at Alexandra Park.

The stable has five in the Group 1 and while three drives were easily settled, Blair Orange will be the new driver for Thefixer and Dunn will partner Ashley Locaz.

There is some irony in the decision, because no driver in New Zealand could have parked out All Stars-trained horses as much as Dunn, predominantly driving for his father Robert, in the last few seasons.

It is a strategy that has worked for him and helped make racing interesting and obviously gained him enough respect to be called in as a pinch hitter.

Dunn would still drive regular partner Classie Brigade should that horse, listed as the emergency, make the field.
