Saturday's racing bulletin

The Five Live selection is Rob Roy each way in the 1510 at Newmarket (all times BST).

Saturday's racing comes from Newmarket, Catterick, Huntingdon, Lingfield Park and Stratford upon Avon.

It is champions day at Newmarket and the champion jockey goes off at 1510.

Kieren Fallon is on board Oratorio, who sets the standard having won two Group One races on his last two starts.

The ground and distance are all in his favour but there will be more value to be had with Rob Roy.

Sir Michael Stoute's colt was held in the highest regard at the beginning of the season only for a series of disappointing efforts to mark him as an underachiever.

But his career has taken a turn for the better recently and he was impressive in victory here a fortnight ago.

It is a big step up in class but Rob Roy will go well at a double figure starting price.

The other Group One race is the Dewhurst Stakes at 1435 - and another outsider Sir Percy should go well.

The colt is unbeaten and will be helped by the drying ground.

Former champion hurdler Rooster Booster is the star attraction in the 1610 at Huntingdon, where the ground is described as good to firm with good places.

Lingfield has a matinee meeting which begins very early at 1115. The polytrack is riding standard.

At Stratford, where the ground is good on the chase course but good to firm good in places on the hurdles course, Fontanesi will be hard to beat in the 1600.

Catterick's ground is good with good to firm places.
