Gordon Lord Byron ran a cracking race to finish third in the Duke Of York Clipper Logistics Stakes on the Knavesmire.
Tom Hogan's Prix de la Foret hero was saddled with a Group One penalty but finished fast to beat all bar winner Society Rock and Lethal Force, who were separated by just a head at the line.
Hogan said: "He could have done with a bit more company, but he's done well and he'll go for the Diamond Jubilee, but I might enter him over longer distances later on."
David Nagle's stable star Maarek was sent off favourite for the Group Two sprint but could never get competitive and finished out of the money.
Winning jockey Kieren Fallon said: "Things went wrong for me. Drawn 18 I couldn't get too much cover and I got there too soon. He was going to walk straight in (to the stalls). He was as good as gold but his shoulder hit the sidebar and spooked him. Other than that, he would have been fine."
Liber Nauticus staked a claim for the Investec Oaks when she got on top close home to land the Tattersalls Musidora Stakes.
The 4-6 shot hit the front about a furlong and a half out and kept on strongly to beat Romantic Settings by a length and a half, with Woodland Aria just behind in third. The Sir Michael Stoute-trained filly, ridden by Ryan Moore, was having only her second career start following a debut success at Goodwood last September.
Moore said: "I was very happy with her because she doesn't actually do a lot. She only does enough, so I was very happy. Hopefully she'll get better as she gets older."
The winner is owned by Ballymacoll Stud, whose racing manager, Peter Reynolds, said: "It was a bit of a muddling race. It didn't really help her, but it was only her second race. She's a bit of a baby and she'll have learned a lot from today.
"Sir Michael will make a decision about Epsom. Some people might say that because she is big and strong she might be more suited to the Curragh (Irish Oaks) but we'll let Michael make that decision. I don't think we saw all her class today. Ryan said she was very nice but it was a muddling race and she's a filly for the future."
