Dwayne Dunn gets the chance to peg back Damien Oliver and Craig Williams in the Melbourne premiership when he heads to Ballarat with a full book of rides.

Dunn starts Wednesday's metropolitan meeting two wins behind the co-leaders with Oliver and Williams both in England this week to ride at Royal Ascot.

There are 13 metropolitan meetings left in the 2014/15 racing season.

Oliver will ride Wandjina in Saturday's Diamond Jubilee Stakes while Williams is on favourite Brazen Beau in the Group One sprint.

Oliver has won nine Melbourne premierships and Williams four, but Dunn is chasing his first title.
