A big day for Aiden O'Brien.

He goes for his 24th Group 1 win of the season with even money favourite Yucatan in the Racing Post Trophy.

I think he is worth taking on. My two against the field are Rivet and Sir Dancealot.

Terrible luck for the brilliant young Irish jockey Jack Kennedy- he returned from a broken leg yesterday and broke it again when his mount fell on his first ride back.
