Plenty of eyes will be on Black Caviar's son Prince Of Caviar when the colt steps out for his season return in a midweek maiden race at Sandown.

Prince Of Caviar made his debut at Sandown in a 1200m race for two-year-olds in late May and did his best work late to finish fourth after settling last in a field of 10.

"I suppose he was a boy there and this time around he's turned into a man," co-trainer Wayne Hawkes told broadcast Racing.com.

The colt, by Sebring out of the unbeaten champion Black Caviar, is scheduled to resume in Wednesday's Vale Martin Riley Plate, a 1300m-maiden for three-year-olds.

He was the $4.20 favourite in an early market on Tuesday.

"He's in great order," Hawkes said.

"I suppose he's lost his puppy fat and it's turned into muscle this time. So if you're putting it into a training performance, what it means is he's improved."

Prince Of Caviar is the second of Black Caviar's foals to have raced.

Her first foal Oscietra, a filly, raced five times for two wins at Geelong and Ballarat, before being retired earlier this year.
