Coronation Stakes stunner Alpine Star could go further in all sorts of ways

Frankie Dettori was the privileged rider of Saturday’s two Group 1 mile winners and in his view Coronation Stakes heroine Alpine Star is more likely than St James’s Palace winner Palace Pier to cope with a step up in trip.

If she stays a mile and a quarter – which Dettori thinks she will – that will open doors for Alpine Star, and potentially even a race like the Breeders’ Cup Turf at Keeneland. Owners the Niarchos family like to have runners at the meeting, and if Saturday’s impressive winner goes on to mop up a couple more top prizes in Europe, connections might fancy a sharp mile and a half in the US to round off the campaign.

Her half-sister Alpha Centauri stuck at a mile after winning the Coronation two years ago, including in the Jacques le Marois, and that might well be a logical target for Alpine Star.
