Trainer Luke Oliver is banking on promising colt Zeletto to propel his Caulfield stable into the spring carnival spotlight.

Zeletto returned from a let-up at Sandown on Wednesday to win the Heading Out Hair & Beauty Handicap to re-affirm plans to head towards the $250,000 Blue Sapphire Stakes during the Caulfield Cup carnival.

A potential shot at the Group One Coolmore Stud Stakes at Flemington is also on the radar should the colt keep stepping up.

"It feels like he's the best horse I've trained," Oliver said.

"From day one he's been so professional and everything he does he does easily and just keeps stepping up."

Zeletto will go to a 1000-metre race later this month before the Blue Sapphire, a race for three-year-olds over 1200m.

"If you run well in the Blue Sapphire you've got to look at it (the Coolmore)," Oliver said.

"He's a colt by Snitzel. It's good to at least be thinking of races like that with a horse like this."

Zeletto took his record to two wins and a second with his 1-3/4 length victory as an odds-on favourite in Wednesday's 1000-metre race for three-year-olds.

Jockey Luke Nolen, meanwhile, believes the Peter Moody-trained Il Cavallo, a close relation to Starspangledbanner, is on his way to living up to his promise after he resumed from a let-up to post his third-straight win in the Hal Baker Plate (1000m).

Il Cavallo ($1.50) sat just off leader Just A Bullet before joining him in the straight and drawing away late to win by 1-1/4 lengths.

"He's a very valuable colt and all we've got to do now is put some black type beside him name," Nolen said.

"I definitely think he has the class to do so. Hopefully we see that come to fruition this spring."

Il Cavallo's win was the first leg of a winning treble for Moody with stable apprentice Regan Bayliss taking the early lead in the Melbourne premiership with his first city double on Brilliant Bisc and Quayside.

"I've just got to try to keep the ball rolling and make my opportunities count," Bayliss said.
