Iron horse Prioritise is a strong chance to back up at Doomben, three days after winning at Toowoomba.

The gelding claimed his 11th career win and his third from three starts at Toowoomba in an Open Handicap (1300m) on Wednesday.

He has been accepted for the Listed Tattersall's Members Cup (1600m) on Saturday.

He has been given a half kilogram penalty for the Toowoomba win, taking his weight on Saturday to 54.5kg.

Prioritise had not won in more than a year and had a drop in class in the Toowoomba race.

Prioritise has raced in 13 stakes races during his career and rarely been disgraced.

"He can be a funny horse but he has been good for us winning nearly $500,000," trainer Steve Tregea said.

"Prioritise is a clean-winded horse and he can have a swim and a potter around which should mean he is fine for Doomben."

"I see no reason why he shouldn't back up."

Oh Five Glory finally had some luck when she won the QTIS Three-Year-Old The Jewel Prelude at the Toowoomba meeting.

Although stakes-placed last year, Oh Five Glory had won only one previous race.

At her six most recent runs she drew double digit barriers.

"We decided to take the barriers out of play by riding her aggressively and it worked," co-trainer Will Hulbert said.

"She can go on to The Jewel at the Gold Coast in a fortnight."
