More Than Ready filly Uni is the one to beat in the Prix de Diane-Gr.1 after a courageous front-running victory over colts in the Prix Matchem-LR (1800m) at Maisons-Laffitte on Thursday.

She is the 170th stakes winner by the Vinery champion who shuttles to Australia for his 17th southern book this year.

Uni (pictured) led under Maxime Guyon but was headed at the furlong by Sepoy colt Executive Force.  Still striding out, she regained the ascendancy and then held off Godolphin’s odds-on favourite Franz Schubert (Dansili).

“She’s a good filly on good ground and should get to 2000 metres without problem,” trainer Fabrice Chappet said.  “She is engaged in the Prix de Diane and we will remain calm before deciding her future with the owners.”

Uni (3f More Than Ready – Unaided by Dansili) won a Deauville maiden in January for owner-breeder Haras D’Etreham and is bred to reign in the Chantilly fillies classic (2100m) on June 18.  Her second-dam Wosaita (Generous) is a half-sister to 1990 Prix de Diane winner Rafha (Kris).

More Than Ready stands at Vinery for a $66,000 (inc gst) service fee.  His Australian 3yo division is on assignment this Saturday spearheaded by Prized Icon (Scone Guineas-RL) and Zunbaqa (Adelaide Guineas-LR).
