Irish trainer Aidan O'Brien trained a record 41st British classic winner on Friday as his filly Tuesday won the Epsom Oaks in a thrilling finish.
The 52-year-old won his 10th Oaks to add to seven 1000 Guineas, 10 2000 Guineas, eight Derbies and six St Legers.
He breaks a record he held with 19th century English trainer John Scott known as the 'Wizard of the North'.
Ryan Moore had the winner in front a furlong out while on the stands' side Frankie Dettori was producing the slow-starting market leader.
They closed all the way to line but in a desperate finish the photographic evidence showed Tuesday had held on by a short-head.
Nashwa (4/1) and Hollie Doyle were back in third with Concert Hall, a stablemate of the winner, fourth.
Tuesday was a remarkable tenth Oaks winner for trainer Aidan O'Brien.
