ROYAL Ascot winner Signora Cabello headlines 56 six-day acceptors for the feature £250,000 Weatherbys Super Sprint at Newbury this Saturday, July 21, with a live performance from Craig David after racing.

First run in 1991, the Weatherbys Super Sprint is for two-year-olds only who were sold or bought in as yearlings by public auction at 'specified sales', or as two-year-olds up to and including March 5, 2018, for £60,000 or less before July 1, 2017, or for £63,000 or less after June 30, 2017.

For each £5,000 paid under £63,000, horses are given a 1lb allowance (the last sale to govern the price if sold more than once).

Colts and geldings are set 9st 3lb before any allowance and fillies 8st 12lb.

The following penalties apply – a winner of a Class 2 race 3lb, of a Listed race 5lb and of a Pattern race 8lb.

Signora Cabello (8st 12lb), representing North Yorkshire trainer John Quinn, is the standout contender on form following her short-head success over Gossamer Wings in the G2 Queen Mary Stakes at Royal Ascot on June 20.

That came on the back of a decisive victory in the Listed Marygate Fillies' Stakes at York in May, after which a controlling stake in the Camacho filly was purchased by Phoenix Thoroughbred Racing.

Quinn said: "Signora Cabello is in great form and I am very happy with her.

"We have left her in the Weatherbys Super Sprint and she is also in the Prix Robert Papin at Maisons-Laffitte on Sunday.

"At the moment, she could very easily run at Newbury, but we have not made our minds up yet. We will make a decision later in the week."

One filly definitely on course to line up is Snazzy (Charlie Fellowes, 8st 10lb), who has finished behind Signora Cabello on her last two starts.

Following an eye-catching debut success on Tapeta at Newcastle in April, the Highclere Thoroughbred Racing-owned filly took third in the Listed Marygate Fillies' Stakes at York, but ran below that level when 17th at Royal Ascot.

The first running of the inaugural £100,000 JLT Cup (2.25pm)is also shaping up to be an excellent race after attracting 29 entries.

The £100,000 prize fund includes a £30,000 contribution from the British Horseracing Authority's Development Fund.
