Lonhro's Pierro wins the rich Golden Slipper

ON October 1 last year, Gai Waterhouse declared Pierro the Golden Slipper winner.

Six months after his winning debut in the Breeders' Plate the prediction came true with the colt giving the trainer her fourth win in the world's richest race for two-year-olds at Rosehill.

“In the heat of the moment you say things you probably shouldn't but I knew that this was a special colt,” Waterhouse said after the Slipper.

“The improvement he had made from his first few gallops to his first race was amazing.”

Waterhouse sent out five runners in the 1200m dash to take on Melbourne filly Samaready, the Blue Diamond winner and the $2.80 favourite.

Pierro ($6.50) was in a beautiful position up on the pace after jumping from barrier one with Snitzerland ($26) wresting the lead from Faustus.

Snitzerland put a couple of lengths on the field rounding the turn and raced away to look as if she would give trainer Gerald Ryan his first Slipper.
