First three-year-olds are ready to run

This month alone, Authorized (pictured) has sired no fewer than seven individual three-year-old winners, including Mano Diao who won a competitive conditions race in Frankfurt by four and a half lengths on 15 April. He is now likely to be aimed at the German Derby.

Futher afield, Cosmo Anecdote broke his maiden on the prestigious JRA circuit, bettering 15 rivals over nine furlongs at Fukushima.

Toruk Macto has been a consistent campaigner for his sire in Turkey, and recorded his fourth win from six starts on 22 April in Istanbul. He can be considered one of the country’s leading three-year-olds.

In addition to Classic hopeful Mano Diao, Authorized also has another exciting prospect in Estrela. The Roger Charlton-trained filly made all to win by four and a half lengths at Newbury last October and holds an entry in the Oaks. Another Authorized to look out for is the highly-rated Good Of Luck, who won first time out in February and is now a likely Derby contender.

Manduro, who rounded off his first year with Mandaean’s victory in the G1 Criterium de Saint-Cloud, has also been enjoying a successful spell of late, recording nine individual winners so far this month.

On 16 April, Man Of Plenty made a successful seasonal debut over ten furlongs at Windsor, a day after Manduro enjoyed an on-the-day double when the Classic-entered Orion Moon and Duca di Mantova won at Longchamp and Milan respectively.

Another of Manduro's talented sons is Sopran Montieri, who will aim to emulate his half-brother Cima de Triomphe when lining up in this year's Derby Italiano. He booked his place in the Italian Classic with an eyecatching victory in a ten-furlong conditions race at Milan.

As well as Mandaean, Manduro has a further three Derby entrants in Bonfire, Apollo Eleven and Mysterious Man, plus the well-regarded Linda Radlett who holds entries in the French Classics and won on her racecourse debut at the start of the month. She finished a creditable third (beaten just a head and a length) on her most recent start and is now likely to step up in class.

Teofilo, who also has his first three-year-old runners this year, has two extremely exciting prospects in G1 winner Parish Hall, who heads straight to the 2,000 Guineas and Light Heavy – winner of the G3 Ballysax Stakes this year and a likely contender for the Irish Derby.

Authorized stands at Dalham Hall Stud at a fee of £10,000 October 1st Special live foal, while Manduro and Teofilo stands at Kildangan Stud at a fee of €10,000 and €25,000 respectively (October 1st terms).
