Mill Stream and Believing supplemented for Sprint Cup at Haydock Park

Believing and Mill Stream has been supplemented at a cost of £20,000 for this Saturday's Betfair Sprint Cup at Haydock Park.

The duo will take on hot favourite Shaquille – who is a best-priced evens market leader with Coral and Betfred – as 23 entries go forward to Saturday's Group One feature on Merseyide.

Mill Stream, who is owned by Peter Harris, has won his last two starts at Deauville in France. The three-year-old Gleneagles colt won the Listed Prix Moonlight Cloud at the start of last month and followed that up with victory in the Group Three Prix de Meautry last week. Both his French wins came over six furlongs – the same distance as Saturday’s contest. Mill Stream is a best-priced 11-1 with Paddy Power and sponsors Betfair. His trainer, Newmarket-based Jane Chapple-Hyam, said: “Mill Stream has come out of his Deauville race in good order, so we have decided to take the opportunity to run him again while he is good form as there are no other options for him until Champions Day.”

George Boughey's Believing was the other horse supplemented at the five-day declaration stage. Believing has won two Listed races and a Group Three contest at Chantilly this season. He is one of two potential runners for the Highclere Thoroughbred Racing team along with Karl Burke's Spycatcher, who was beaten a short head by King Gold in the Prix Maurice de Gheest at Deauville last month. Believing is a best-priced 16-1 with most bookmakers, while Spycathcer is 10-1 with the sponsors, Paddy Power, Betfred and Unibet.

The Julie Camacho-trained Shaquille is a warm favourite to continue his Group One-winning exploits on Merseyside. The three-year-old has already won at the top level this season, taking the Commonwealth Cup at Royal Ascot
