Improving New Zealand stayer Our Kazz also stepped up to a stakes win in style after a masterful Damien Oliver ride in the $100,000 Listed Turfgrass Adelaide – Port Adelaide Guineas.

Young trainer Craig Ritchie was worried Our Kazz wouldn’t have enough pace to stay with his opposition over the 1800m but Oliver assured him there would be enough speed in the race.

Oliver settled the gelding well back in the field but came with a barnstorming run to win easily and smash the track record set in 1991 by Shivano Miss.

"They went really hard up front and set it up for him," Oliver said.

"He settled nicely and really let down well. He would have won by further but he pulled up a bit when he hit the front. He’s definitely a better chaser."

Ritchie, who attributed the win to Oliver’s ride, said the gelding would improve over more ground.

"He was ready to win today but will keep going as the distances get longer," Ritchie said.

"He finished a close fourth in the New Zealand Derby behind Leica Guv and that’s pretty good form. He’ll run in the Veuve Clicquot next start then the Derby."

Craig’s father, legendary Kiwi trainer Frank, prepared Showella to win the Listed Veuve Clicquot Stakes in 1999. She then went on then went on to win the SA Derby.

"The trip to Adelaide really made Showella so, hopefully, he can do the same," Ritchie said.

Local gallopers filled the minor placings with Squillani battling on well to finish second, while Pray In Vain finished third.

The well-supported favourite, the Colin Alderson-trained Hillsgrove, was never in the race early but charged home late to finish seventh.
