Ryan Moore and Aidan O’Brien looks set to dominate Royal Ascot, once again, according to Bookmakers.

Legendary trainer O’Brien, and his number one jockey Moore, are looking to defend their top trainer and jockeys prizes at Ascot.

The Ballydoyle handler attempts to claim the top trainer award for a fourth-year in-a-row, and for a ninth time overall.

Moore is looking to claim the jockey prize for a remarkable eighth time in nine years.

O’Brien and Moore are both odds-on. Moore is the 4/6 favourite with William Hill to be the top jockey at with Aidan O’Brien 2/5 to be the top trainer.

“It is not quite as clear cut as it has been in recent years but it is difficult see anyone breaking the dominance of Aidan O’Brien & Ryan Moore,” said William Hill spokesman Rupert Adams.
