The latest betting news, going updates and non-runners

After a week when Aidan O'Brien dominated the Derby trials at Chester, he tries to extend the run in Lingfield's equivalent with Sir John Lavery. The Group 3 Chartwell Fillies' Stakes is also on that card.

At Haydock, there is a mixed card where the big clash is likely to be in the weighing room. Besides that, there is the Swinton Hurdle as well as the Listed Spring Trophy for the Flat riders.

Haydock and Ascot often go together on a Saturday and in Berkshire today the Victoria Cup is the feature race, supported by the Listed Buckhounds Stakes.
