Connections of both Mill Stream and Believing have paid the £20,000 supplementary fee with 23 remaining in contention for the Sprint Cup at Haydock this Saturday.
Both Mill Stream and Believing have been supplemented to take on top sprinter Shaquille at Haydock this weekend.
The former impressed when a ready winner over Garrus in the Group 3 Barriere Prix de Meautry at Deauville last month, while the latter recorded her third success on the 2023 campaign when landing the Listed Flying Fillies' Stakes at Pontefract last time.
Newmarket-based Jane Chapple-Hyam, said today: "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 in good form as there are no other options for him until Champions Day."
Ralph Beckett has left both Kinross and Lezoo in contention at the five-day stage but suggested he will rely on the latter, who got back to winning ways in the Listed Hopeful Stakes at Newmarket to provide Andrea Atzeni with a winner on his last UK ride.
Beckett said: "Lezoo will go to Haydock for the Sprint Cup as it doesn't matter what the ground is. I don't know who will ride her yet and we will find that out in the coming days.
"It depends on the weather for Kinross as he won't run unless it is good or softer. I'm not going to run him over six furlongs on quick ground at Haydock Park as that won't play to his strengths.
James Doyle looks set to be reunited with the general 10/11 market leader Shaquille for the first time since the pair strode to victory in the Carnarvon Stakes at Newbury back in May.
Aidan O'Brien has both The Antarctic and Aesop's Fables in the mix at this stage, while Regional, Run To Freedom, Sacred, and Khaadem all feature.
