Campaldino, a Sydney Cup hopeful, has to undergo a fitness trial to confirm his participation in Randwick’s two-mile showcase, prompted by a routine vet exam showing cardiac arrhythmia.

Adrian Bott, co-trainer, confirmed no evidence of the ailment after the second-place effort in Saturday’s Chairman’s Handicap (2600m), and no past occurrences for the horse.

“He presented with cardiac arrhythmia in the tests this morning,” Bott said.

“He’ll go through the ECG process. He was checked immediately following the race (on Saturday) and all the vital signs, everything was all in order.

“It’s a bit of an unusual case. He’s never had any history. It’s something that has just popped up.

“He hasn’t done any strenuous exercise, but the stewards did their Sydney Cup inspections (on Tuesday) morning and that’s when it was detected.”

The horse has provided blood samples and must gallop under scrutiny from stewards on Thursday for race clearance.

Bott stressed their commitment to the horse’s well-being, stating Campaldino would contest the Sydney Cup (3200m) only upon full health assurance.

Approval would see the prior season’s Brisbane Cup (3200m) champion poised for a solid run.

“It’s the program and campaign build-up we have used successfully before to win the Cup with Knights Order and The Offer, so he has followed that path and seems to be peaking at the right time,” Bott said.

“It was an excellent run on Saturday. He is proven at the two-miles. Bit of an awkward draw but he’s got tactical speed to offset that.”

At $8 in betting, Campaldino has barrier 14 from Tuesday’s draw, with Tim Clark riding.

Top pick Mr Monaco ($5) drew the widest of the 16 runners, having succeeded from a wide path in last start’s Manion Cup (2400m), while River Of Stars and Soul Of Spain have stalls six and 12.
