The 19-year-old has enjoyed a dream start to 2018 – winning the QIPCO 2000 Guineas at Newmarket in May and the, the following month, landing the Investec Oaks on Forever Together.
Having ridden Saxon Warrior in the past, plus being his partner in all his homework, he was the natural choice to partner the 3-1 chance in the Guineas with stable jockey Ryan Moore being on duty at the Kentucky Derby.
The race went smoothly for the combination and at the line they had a length and a half to spare over Tip Two Win.
The winning jockey said: “It’s very special, I’ve got to say a huge thanks to dad and the owners for giving me the chance to sit on him and hopefully I didn’t mess up today.
“He travelled beautiful and I thought we were the winner the whole way. I probably got a bit excited at the two pole when I gave him a squeeze a bit early.
“He’s an absolute monster of a horse so you never know, he could improve again. I was very impressed, I thought he was a very good horse even on his homework, we’ve made no secret of it, and I think he’s very, very good.
“If I had to put my neck on the line I would say his optimum trip would be about a mile and a quarter, he’s not slow but he’s bred to stay. He’s very relaxed so I wouldn’t be at all surprised if he got a mile and a half but it’s not my decision.”
Forever Together became the first maiden to win the Oaks since Sun Princess in 1983 and O’Brien said: “It’s absolutely incredible to win. I didn’t expect to be here but when you’re riding for Dad [Aidan] anything can happen and it’s paid off twice already [Saxon Warrior, 2000 Guineas].”
He also finished runner-up aboard Saxon Warrior in the Coral-Eclipse.
