Ollie Sangster is biding his time before finalising plans for Sunday's Tattersalls 1,000 Guineas (3.40), but has warned that only one of Flight or Simmering will run in the Curragh Classic.
Last year's Breeders' Cup winner Starlust is set to prepare for Royal Ascot in Saturday's Betfred Temple Stakes at Haydock as he embarks on his final season before going to stud in Australia.
Winner of the Turf Sprint at Del Mar for trainer Ralph Beckett and owners Jim and Fitri Hay, Starlust has next month's King Charles III Stakes, for which he is priced at 10-1, as his primary target.
