The Big Opal has unfinished business at Riccarton and the Kevin Myers-trained jumper is in exactly the right order to seal the deal in seven days' time.
The Storm Creek gelding went into last year's Grand National Steeplechase as a warm favourite off the back of his win in the Koral Steeplechase, but only for rider Matt Gillies to lose his irons 1200 metres from home and they subsequently parted company at the final fence.
The Big Opal, with Shaun Fannin replacing a side-lined Gillies, will again start at short odds in next weekend's Racecourse Hotel & Motor Lodge-sponsored feature after he was untroubled yesterday to defend his NZI Koral title.
"He measured his fences well and relaxed and got into a good rhythm so it's all looking good," Fannin said.
"He makes up a lot of ground at his fences and he's got that flat speed to increase the tempo and push the issue when we need him to."
