DETTORI'S ARREST!

Frankie finally decides on his St Leger mount

- DAVID YATES

ARREST is the new 3-1 favourite for tomorrow's Betfred St Leger after Frankie Dettori chose the John and Thady Gosden trainee as his final Classic ride.

The 52-year-old, who retires from the saddle at the end of the year, had originally been jocked up to ride Clarehaven stablemate Gregory.

But the likelihood of rain-softened ground at Town Moor has prompted the Italian to switch horses.
