The colt by Sebring has been named Prince of Caviar

Will be trained by Team Hawkes

Black Caviar is due to foal this year to Sebring's sire More Than Ready (USA)

Crikey, they're greedy trying to extract a foal every year.
My research indicates that when one uses a mare as a breeding machine, they don't have time to recover, they need at least one year off, as one prominent breeder agreed and does with great success. Otherwise the foals don't tend to get the full benefit of the vitamins, minerals, enzymes, and proper formation and conformation of highly crucial areas. If a mare doesn't have time to recover and rebuild herself (lets not forget she's lactating the whole time), this can lead to dead, slipped, or inferior foals.

Already nominated for the 2018 $1.5 million Ladbrokes Blue Diamond Stakes.

According to co-trainer Michael Hawkes, Prince of Caviar is progressing well

"He's been in the Rosehill stable to learn the system. He got to have a good look around and did everything right education wise. He's a lovely, well balanced colt."

Oscietra back in work

Won Geelong Synthetic Race 3. Went quickly to the lead, got one length on the field at the turn then held them safely down the straight.

Next run on turf in the city. Perhaps in 3 weeks' time at Moonee Valley. Trainer Hayes confident that she'll be a black type winner.

I don't know much about conformation or strides, but I don't think it's a matter of timing or happenstance that she resumed on synthetic.

Oscietra has been nominated for both the Thousand Guineas & Caulfield Classic in October

Yes, but team Hayes nominate all their horses for everything, especially 2yo's, he says so himself.
He says that Catchy is as good as Miss Finland, good type of horse, but can't see it myself, he probably knows something about the horse which we haven't seen.
