Horse-by-horse guide to Saturday's William Hill St Leger

Dashing Willoughby won the Princess Of Wales’s Tattersalls Stakes at Newmarket. He didn't have much impact in the Qatar Goodwood Cup next time. His best form is with some cut.

IL Paradis won in Curragh handicap and finished third in the Weatherbys Hamilton Lonsdale Cup at York.

Logician won the Sky Bet Great Voltigeur at York last time. He is a worthy favourite for Saturday's William Hill St Leger.

NAYEF ROAD beat Constantinople by a neck in the Gordon Stakes. He will be last of five behind Logician at York next time.

Rusty was beaten less than a length in the Investec Derby. Sir Dragonet won the Chaser Vase. Rusty was outpaced over a trip at the Curragh.

SIR RON PRIESTLEY is the front-runner for Saturday's William Hill St Leger. He's won handicaps from 86 to 98 this season and landed the March Stakes at Goodwood last time.

Technician won the Geoffrey Freer at Newbury last time. He has disappointed in the Chester Vase and Gordon Stakes this season.

Logician is short enough for a first venture into Group One company. Sir Dragonet is his main market rival. Preference is for stablemate IL PARADISO. Ron Priestley is a double-figure price.
