Alex Hammond blog: Piz Badile looks the main Derby danger to Aidan O'Brien trio while Concert Hall can sing Oaks tune

Sky Sports Racing presenter Alex Hammond looks ahead to Epsom Classics. Piz Badile looks the main Derby danger to Aidan O'Brien trio. Concert Hall can sing Oaks tune.

Lester Piggott died at the weekend aged 86. Lester retired in 1995 but his career was full of highs and lows. His comeback at Breeder's Cup on Royal Academy was one of the memories that was imprinted on his impressionable brain as a teenager. He was to ride his final British Classic winner on Rodrigo de Triano in the 2000 Guineas. Alex Hammond was there and had a front-row seat.

Piz Badile will be ridden by Frankie Dettori for the first time in the Derby. Stone Age, Changingoftheguard and Star Of India are the other colts in this year's race. Aidan O'Brien's son Donnacha is the youngest trainer of a Derby winner. Charlie Appleby has won two of the past four Derby runs. Nations Pride is worth £75,000. Sir Michael Stoute has five Derby wins. Desert Crown is a worthy favourite at 13/8 with Sky Bet. The Derby is run in memory of Lester. Cazoo and Epsom racecourse sponsor the race this time.

Piz Badile looks the main Derby danger to Aidan O'Brien trio. Hollie Doyle is smashing down all the barriers thanks to her phenomenal talent. If she wins the Cazoo Oaks on Nashwa, she would be the first female to ride the winner of a British Classic. Nash wa is second only to stablemate Emily Upjohn in the market at 4/1 with Sky Bet. Concert Hall, Tuesday, Thoughts Of June and outsider The Algarve are still in Friday's race for the Ballydoyle maestro.
