St James's Palace Stakes (Group 1) (Colts)

Four wins on the spin culminate in a dominant 3-length 2000 Guineas success, where Bow Echo travelled supremely and quickened clear — a performance that marks him as the one to beat here, with proven course-and-distance form and 45 days to recover in good order.

Bolted up in the Irish 2,000 Guineas last time, quickening smartly to win by three lengths and advertise top-class mile form; proven on today's going and distance, with a top course jockey aboard from stall 1, though reversing Newmarket form remains the chief task.

Lord Britain won a handicap at Kempton last time on the all-weather, but is yet to prove effectiveness on turf and looks out of depth here; the first-time headgear may help, but this trip and surface combination remains unproven and our figures rank him last of six.

Power Blue showed Group 1 credentials when fourth in the Irish 2,000 Guineas last time but faces a re-opposing rival it couldn't beat there, and ranked fifth of six on our figures, a repeat performance looks unlikely to be enough here.

Puerto Rico brings a fine recent profile with two G1 victories to its name and an upward curve through the backend of last season, and a closing fourth in the Poule d'Essai at Longchamp on its return suggests the spark remains — the key question is whether it can reproduce that form on quicker ground today.
