Shaun and Emma Clotworthy are confident that Diesel's free-running style can be put to good use over more ground.
The Byerley Park trainers have a Group One dream for the stayer, who took another winning step toward his autumn target with a commanding victory in the Bupa New Zealand Handicap (2400m) at Te Rapa on Saturday.
Diesel is now an $18 chance in next month's Barfoot & Thompson Auckland Cup (3200m).
"We're planning toward that and he'll definitely run the distance," Emma Clotworthy said. "He'll most probably have one more run before the Cup."
Versatility is another quality boasted by Diesel, who is a multiple winner on top of the ground and he had no trouble coping with the Slow 7 going at Te Rapa, where he was never headed. "He likes to be out in front and dictating the race," Clotworthy said.NZ Racing Desk
