One horse, jockey and trainer to follow on day five of Royal Ascot

The first Group One of the day is the Fillies Coronation Stakes over a mile and the leading mare in this one looks to be the Roger Charlton trained Quadrilateral.

Last season the three year old filly was unbeaten on all three of her starts showing her versatility with ground winning on good and good to soft conditions.

She ended her juvenile career with a Group One success in the bet365 Fillies' Mile and she started this season as favourite in the 1000 Guineas.

She ran slightly below par that day and looked like she needed the run and there are no excuses now with a weaker field.

It may look an obvious choice but Aidan O'Brien has his best looking team of runners on Saturday and after gaining some winners this week he sets up a big final day to grab the trainers title.

We think he has two big chances on Saturday starting with More Beautiful in the Group Two Queen Mary Stakes having been a very impressive winner on debut in a five furlong contest at Naas.

Hopefully the ground will dry out before the race with that win coming in very quick conditions but with not much rain forecasted she looks the one to beat.

In the Group Two Coventry Stakes he fields Admiral Nelson. The son of Kingman cost a hefty £440,000 as a yearling and on debut at the Curragh went o to score very nicely to suggest he can be a very special youngster for the Ballydoyle team.

O'Brien has had nine winners in this contest and has a very strong chance of making it 10.

Tom Marquand has not had the pick of the rides at Royal Ascot so far during the five days but on the Saturday he has a huge chance to land a winner.

Having a nice book of rides his best looks to come in the first race when he sits on the William Haggas trained Aplomb.

The very unexposed four year old that made a very encouraging return over five furlongs at Newmarket last week.Tom Marquand takes the ride and with him just kicking into gear and it being a weak race overall he looks one of the more likelier types to go well.
