The Richard Collett-trained My Callisto showed his determined spirit when taking out the West Brook Wines 1600 at Avondale on Wednesday.

The three-year-old son of Rock ‘n’ Pop was caught three-wide the entire trip after jumping from his wide barrier, but he was able to gather in the leaders down the home straight to win by half a length over Sheez Leica.

Jockey Andrew Calder was pleased with the result after the pair finished runner-up on debut at Counties last month.

“I don’t want to get too carried away with a maiden win, but he is going to make a really nice staying horse later on,” Calder said. “He’s destined to go 2000m and further.

“He was a bit green last time. Today he did things a lot better and I think blinkers will help him a lot.

“We are happy to let them learn a bit at this stage of their career.”

My Callisto became the 34th winner for Waikato Stud stallion Rock ‘N’ Pop, who stands at the Matamata farm for a fee of $7,000+GST.
