Donnacha O'Brien executed the perfect ride aboard Magna Grecia to land his father a third 2000 Guineas win in a row, and a record 10th win overall.
In doing so, the Ballydoyle trainer becomes the first man in over 180 years to saddle the winner in the season's first classic for the third time in succession.

The 11/2 shot appeared to be only the stable's second-string, with the unbeaten Ten Sovereigns, ridden by Ryan Moore, heavily-fancied beforehand.
But it was the 20-year-old son of the record-setting trainer who went on to claim back-to-back wins in the race after winning impressively aboard Saxon Warrior 12 months ago.
The first trainer to win 3 #2000Guineas in a row since the 1830s!
Aidan O'Brien and the @Ballydoyle team are sensational. 👏#Newmarket pic.twitter.com/zAiNdVKglk— Virgin Media Sport (@VMSportIE) May 4, 2019
The 66/1 shot Richard Hannon-trained King Of Change provided somewhat of a shock, chasing the winner home in second, while Skardu, saddled by William Haggas, just pipped the Kevin Prendergast-trained Madhmoon for third.
Prendergast, the 86-year-old trainer from Kildare, won the race all back in 1977, but the veteran trainer was denied a fairy tale victory on this occasion.
The day ultimately belonged to the Ballydoyle brigade and the winning trainer, speaking to ITV, attempted to put the achievement into words.
We feel so privileged to be part of this team. It's so big; and it's so vast; and there are so many people and so many different areas...It's great for everybody. It's very exciting. I can't tell you how excited we are.
We thought he would get a mile well but he's after developing a lot of speed as well. Even though he had plenty of pace last year you'd always say he wouldn't mind stepping up in trip. But he's starting to travel this year.
When the champion trainer won his first renewal of the race down the Rowley Mile, Donnacha O'Brien had yet to be introduced to the world. Over two decades later, and after winning his second renewal of the race, the winning jockey referred to his father as a "genius" when interview immediately after the race.
"He's a genius."
@donnacha_obrien with big praise for his Dad after the Father/Son Trainer/Jockey combo wins the #2000Guineas yet again! 🐴#Newmarket pic.twitter.com/HqJl1cWrCY— Virgin Media Sport (@VMSportIE) May 4, 2019
Chatting to ITV, the jockey said:
It's unbelievable. I don't think people give him enough credit. You see all the fancied horses that are coming to this Guineas and one by one they dropped away. And for him to be able to turn out two of them and make them turn up on the day in great condition is unbelievable.
It's something he probably doesn't get enough credit for. He's a genius.
