Whirl can make full use of her weight-for-age advantage to win the Qatar Nassau Stakes at Goodwood on Thursday.
The three-year-old fillies receive 9lb from their elders in this 2000m event and over the past 10 years the Classic division has firmly held sway, winning seven times.
While fellow Aidan O'Brien runner Bedtime Story and Coronation Stakes heroine Cercene also tick that age box, preference is for Whirl who already boasts Group One-winning form at this distance having landed the Pretty Polly Stakes at the Curragh last month.
She had to dig deep to fend off Kalpana by 1.25-lengths, with that filly giving the form a huge boost when only just denied by Calandagan in last week's King George at Ascot.
Whirl had previously finished a neck second to dual Oaks winner Minnie Hauk after attempting to make all at Epsom, so her top-level credentials bare the closest examination.
Merchant makes the leap to Group Three company in the Gordon Stakes after a fine victory in handicap company at Royal Ascot.
The three-year-old has been steadily making his way up the ranks, having won one of three juvenile starts last term before returning with a fair handicap third at Newmarket in May.
William Haggas' charge looked the one to take out of that race and so it proved as he prevailed in style at York just two weeks later, beating subsequent Queen's Vase third Rahiebb, who reopposes here, and last week's Ascot winner Many Men with the minimum of fuss.
He was then sent off favourite for the King George V Stakes and was again a ready victor over Serious Contender, who has gone on to run Lambourn to a length in the Irish Derby, giving the form plenty of weight.
Egoli can go well at a decent price in the Markel Richmond Stakes.
Trained by Ralph Beckett, this son of No Nay Never was only fifth on debut but has not looked back since, winning a York maiden before following up in a Newbury novice contest last time, running out a decisive winner after racing prominently on each occasion.
Egoli has a bit to find with the likes of Coppull on official ratings, but he has progressed with every start so far.
Beckett can also be on the mark at Epsom with Relevance, who lines up in the British EBF Fifinella Fillies' Handicap.
Beaten by the 98-rated Life Is Beautiful on her second juvenile start, Relevance returned from 216 days off the track to win a 1400 Salisbury novice last month by just a head but should feel the benefit of that return here.
