Top filly Maid Up 16-1 for St Leger after being added to Doncaster field

Maid Up, winner of the Group 3 March Stakes at Goodwood last month, has been supplemented for Saturday's William Hill St Leger at Doncaster at a cost of £50,000.

The Andrew Balding-trained filly, owned by Brightwalton Bloodstock, holds an entry in Thursday's DFS Park Hill Stakes – often referred to as the fillies' St Leger – but connections have decided to have a crack at the big one, with sponsors Hills making her a 16-1 shot.

Lah Ti Dar remains engaged among 16 possibles for the final Classic of the season, with ante-post favourite Kew Gardens leading seven contenders for Aidan O'Brien.

Maid Up, whose only defeat in her last five starts came when beaten a short head by Pilaster in the Lillie Langtry Stakes, gave connections great encouragement with a one-and-a-quarter length victory in the March Stakes.

Balding said: "It's never an easy decision as it is an expensive supplementary but she has won a Leger trial quite cosily.

"The owners are very sporting people and you get only one opportunity to run in the St Leger so they were quite keen on it. She's in great form so we thought we'd give it a go."

William Hill make Kew Gardens their 5-4 favourite, with Lah Ti Dar, who has the option of running at the following day's Arc trials meeting, next best at 7-2.

The firm's spokesman Rupert Adams said: "We're absolutely delighted with this field for the William Hill St Leger on Saturday. Kew Gardens is a hot favourite but there is some great value around with the likes of Old Persian (6-1) and Latrobe (10-1)."

The four-day meeting at Doncaster starts on Wednesday and a mainly dry outlook is predicted.

Clerk of the course Roderick Duncan said: "Following 8mm of rain on Saturday the going is now officially good to soft, good in places. There is a risk of some rain Tuesday into Wednesday morning, but it is forecast to be dry from Wednesday onwards."
