Her old rival, Just The Judge, is arguably more likely to get home but the value could instead prove to be the forgotten Hot Snap (3.15).
Once again, the race could have a key bearing on life after Frankel at Warren Place, the superbly bred Hot Snap having managed to overcome inexperience to win her sole start at two, over a mile at Kempton.
Hot Snap, though, looks like the sort of horse for which trials were designed, desperately in need of experience but beautifully bred, full of potential and now much more likely to show her best form when it matters most.
Hot Snap, who is a half-sister to the multiple Group One-winner Midday, had made only one previous start before Wednesday's race, in a maiden on the all-weather at Kempton last autumn.
Sky Lantern was carrying a 3lb penalty for her success in the Group One Moyglare Stud Stakes last season but Hot Snap showed her inexperience throughout the race and can only improve significantly for the run.
Just The Judge, who proved little more than that she is still alive and sound in a racecourse gallop before racing, remains favourite for the Classic at 6-1, but she has been joined at the top of the market by Hot Snap, who gave Sir Henry Cecil his eighth success in the Nell Gwyn Stakes later in the afternoon.
Hot Snap, owned like Frankel by Saudi prince Khalid Abdulla, had won her only previous race, a one-mile maiden fillies' stakes over a mile at Kempton in September.
Hot Snap is a half-sister to star mare Midday, formerly trained by Cecil, who was confirmed as being in foal to Frankel on Tuesday.
His licence temporarily passes to his widow Jane, with Frankel's brother Noble Mission, half-sister Joyeuse and Hot Snap set to run for her next week.
