Trainer Toby Edmonds has decided to wait a week with rising star Cadogan and rely on one proven sprinter in the Listed Ascot Handicap at Doomben.

Edmonds entered Cadogan, Keen Array and Tyzone for Saturday's Ascot Handicap (1200m), one of the oldest feature races in Queensland .

He accepted with Keen Array and Tyzone who has been scratched to run in the Hall Mark Stakes at Randwick.

Cadogan was earmarked as a possible Group One Stradbroke Handicap horse after three wins and an unlucky fourth in the Magic Millions QTIS race in the summer.

He showed he had lost none of his dash with a fast-finishing second in a Gold Coast trial two weeks ago.

"Cadogan can wait a week and he will resume in a Class Six at Eagle Farm on Saturday week," Edmonds said.

Keen Array showed he was getting back near his best form with a Gold Coast trial win.

Originally trained by the Hayes-Dabernig partnership, Keen Array won the 2017 Group Two Gilgai Stakes.

After struggling in Melbourne in later campaigns Keen Array was sent to Edmonds earlier this year.

"He seems to be doing well and I did like his trial. He ran down another of my horses Whypeeo in the final 150 metres," Edmonds said,

"Whypeeo always trials well so it gives you an idea of how Keen Array is going."

James Orman rode Keen Array in the trial but Jeff Lloyd takes over on Saturday.

Edmonds has booked Blake Shinn for Tyzone at Randwick and thinks the winner of 15 races can be hard to beat.

Tyzone won the Listed Goldmarket Stakes two runs back and then was an unlucky fifth in the Listed Weetwood Handicap two weeks ago.

"Things didn't go his way in the Weetwood as he probably should have got into the race with the eventual winner Sexy Eyes," Edmonds said.
