(CNN)Trainer Aidan O'Brien made history in Newmarket Saturday, becoming the first trainer to win the 2,000 Guineas three times in a row in nearly 200 years.
The Irishman's Magna Grecia, ridden by his son Donnacha O'Brien, won the first Flat racing Classic of the season to also give O'Brien his 10th win in the prestigious race.
"We couldn't be happier," O'Brien told ITV Sport after his third successive win, following in the victories of Saxon Warrior and Churchill. "It's incredible. It's a massive team effort. It's really exciting."
Magna Grecia finished comfortably ahead of King of Change in second by two-and-a-half lengths. Skardu was third.
"I don't think people give him enough credit," said winning jockey O'Brien, who rode Saxon Warrior to victory in last year's race.
"He's a genius and I'm just learning as much from him as I can."
