ACAPULCO is literally head and shoulders above her rivals in the Coolmore Nunthorpe Stakes at York on Saturday.

Described by trainer Wesley Ward as "monstrous", the huge American filly also has the class to match her heavyweight physique.

She should, then, convincingly step up to the top table to become the first juvenile to win the Nunthorpe since Kingsgate Native in 2007.

As a young filly, Acapulco is in receipt of nearly 2st from many of the Nunthorpe protagonists but racegoers who see her in the flesh at York could be mistaken for thinking it should be the other way around, such is her size and scope.

The daughter of Scat Daddy is visually mature beyond her tender years, and illustrated the point on only her second racecourse outing at Royal Ascot.

Coolmore's representative was sent off the 5-2 favourite for the Queen Mary at Royal Ascot, and those who had lumped on could not have wished for a smoother passage.

Acapulco produced arguably the most domineering performance of the Royal meeting with a clinical dismantlement of a strong field.

The form - and this is not often the case with the Queen Mary - also looks watertight as runner-up Easton Angel looks particularly smart.

As does Besharah, who has since claimed a Group Three by three lengths and more.

Trained with characteristic poise by the likeable Ward, Acapulco has been readied for this assignment ever since that day in Berkshire.

Ominously, too, for those in competition, the chances this athletic thoroughbred can make even further progress from the Queen Mary appear high.

How she handles cut in the ground is anyone's guess, but the forecast for the rest of the week looks fairly decent, so York is highly unlikely to turn into a rare old slog.

Even if that is the case, Acapulco hardly looks a horse to shirk any kind of gun-slinging skirmish.

Tac De Boistron should not be forgotten in the Weatherbys Hamilton Lonsdale Cup.

Lots of attention will be lavished upon the Goodwood Cup form from last month, but it might be best to shift one's focus towards Marco Botti's stayer.

It all went spectacularly wrong for Tac De Boistron at Royal Ascot - he was all but pulled up - but his trainer might still regret running him in the Gold Cup.

The ground was, after all, way too fast for the eight-year-old grey, who is a top-notch operator when the mud is flying.

His form in the Yorkshire Cup last season, though, tends to suggest he is perfectly at home on good ground as he was only beaten a neck by Gospel Choir, who was getting weight from Tac De Boistron.

It was a similar story at Chester on his seasonal debut, too, as he could not claw back a length-and-a-quarter deficit from Clever Cookie, who was in receipt of 7lb.

Back on level terms with most of these, the dual Group One winner can make it count.

Mick Channon's horses are nearly always overpriced, so there should be mileage in following Bossy Guest for the Sky Bet City of York Stakes.

The colt has not really kicked on since his terrific run in the Guineas, but that perhaps does not tell the full story, with bad luck and no pace partially to blame for slightly subdued efforts at Ascot and Newmarket.

On the face of it, he was then outclassed behind Solow et al in the Sussex Stakes at Glorious Goodwood.

This is probably true, but the son of Medicean was forced to race wide from flag-fall after a slightly wayward start and was eventually beaten six lengths.

With a big field heightening the chances of a truly-run encounter, Bossy Guest will have no issues reverting to seven furlongs on the Knavesmire - as long as there is no excessive rainfall.

Scooner looks ship shape for a big run in the Breeze Radio Handicap at Salisbury, with Whitecrest of interest in the AD Sports Council Handicap at Sandown.

Useful grey Scurr Mist can send Wolverhampton punters home satisfied by winning the FCL Global Forwarding. Making Logistics Personal Handicap.

Waddingtown Hero can add to his Ffos Las gains in June by taking top rank in the Mint Staffing Solutions Handicap Chase at Bangor.
