JIMMY Mangan has joined the increasing roster of trainers for Alan and Ann Potts after the Yorkshire couple purchased the exciting Tallow winner Castlebrook.

The four-year-old son of Oscar had a bloodless victory in Tallow on February 5th, running in the colours of Mangan’s wife Mary and representatives for the Potts were soon in touch.

The good news for Mangan, who trained Monty’s Pass to win the 2003 Grand National and who features in Saturday's Big Interview in The Irish Field, is that the gigantic bay remains in the yard. He is very hopeful for the future.

“He’s a very big four-year-old but he has great potential and hopefully he’ll be very lucky for them. He might get me back into the big time again” says Mangan in Saturday’s edition.

“He does everything effortlessly with the track horses I have like Winter Magic and Kilcrea, who are alright and win their races. But this fella never comes off the bridle when he’s working with them and he’s only four.

“He’s 17.2 and a half. I told some shrewd horsemen that I fancied him below at the point-to-point in Tallow. They told me after that they went up to the parade ring, had a look and said there was no way he could win he was so big; he shouldn’t even be broken! And he wins in a canter.

“He may go for a bumper but his future will be chasing in time. He’s a big, massive horse. Whatever he does in bumpers or over hurdles will be a bonus. Chasing will be his job because he’s an absolutely incredible lepper.

“I’ve actually never met Ann and Alan Potts but ‘twas very decent of them to let the horse with me. I will treat him like one of my own and hopefully we’ll have a bit of luck.”
