Unbeaten as a juvenile, Pierro suffered his first defeat in the Caulfield Guineas when he was chased down by All Too Hard after a tough run on the speed.
Pierro will get his first chance to stake a claim for the title of Australia's best colt when he resumes in the group two Hobartville Stakes (1400m) at Rosehill tomorrow.
He is a resounding favourite at $1.75, ahead of the unbeaten Rebel Dane ($4.60) and his Waterhouse-trained stablemate Proisir ($7.50).
Proisir was runner-up in the Spring Champion Stakes at just his fourth start and wasn't disgraced when eighth in the Cox Plate at his fifth.
Like Pierro, he hasn't raced since the weight-for-age championship but his future looks bright.
However, when it comes to the Hobartville, Newnham echoes the sentiments of punters and says Pierro is the pick of the pair as he is naturally more forward than his chunkier stablemate.
"They're a bit different physically. Proisir is more a heavily built colt so it's only natural he would take a bit longer to come to his peak.
"I just hope they both finish their campaigns with group one wins. One has done it and one is promising to do it."
Pierro is undefeated first-up and has never lost a race in Sydney.
He will jump from barrier nine, while Proisir has drawn the outside in the field of 11.
Earlier on the card, Ichihara, who has a liking for the distance and has proven her credentials, will still face a tough test against some promising gallopers.
The Allan Denham-trained 3-year-old has paid the price for her consistency and will carry top weight of 59kg in the listed Fireball Quality which is bursting with up-and-coming gallopers.
Among her rivals will be undefeated Rick Worthington-trained filly Golden Sunshine, smart Victorian Lampedusa for Peter Moody and the John O'Shea pair of Knight Exemplar, to be ridden by James McDonald, and Charge Account.
They are progressive 3-year-olds and Ichihara will be conceding at least 4.5kg to them all. AAP
