Sussex teenager Jason Watson wants to upset one of the biggest names in racing.

But the champion apprentice jockey admits the weather might not be on his, or Tony Bloom’s, side.

Watson is on board Bloom’s hopeful Withhold in the British Champions Long Distance Cup on Royal Ascot’s all-star card.

Odds-on favourite Stradivarius will be expected to dominate under the guidance of Frankie Dettori but Watson, 19, fancies a few surprise results after heavy rain during the week.

He thinks Withhold could one of those to watch.

Watson, born in Brighton and brought up in Lewes, told The Argus: “We have got the best stayer in the world to deal with but Withhold is a very talented horse.

“He won his last race very easily and this seemed the obvious next step.

“His running style is very different to Stradivarius and he could potentially be one of the likely ones to almost catch him out.

“At the same time, I believe the ground might be a little too soft for us. I think Withhold is probably a better horse on good ground.

“I seem to get on quite well with him and he is a lovely horse to ride.”

Albion chairman Bloom has three runners on the QIPCO British Champions Day card with Librisa Breeze in the opening race and Flaming Spear in the Balmoral Handicap.
