Favourite Orchestra held on by a nostril to win a thrilling MBNA Chester Vase.
For much of the Investec Derby trial it seemed to be a case of how far the 3/1 Aidan O'Brien-trained colt would win by, such was the purpose he travelled with under Ryan Moore.
Nipping through a gap on the home turn he set sail for home and the race looked over - only for Romsdal (9/2) to emerge from the pack.
He closed hand-over-fist in the final 100 yards and only failed to get there by the narrowest of margins.
The pair were eight lengths clear of 7/1 chance Scotland in third.
Moore said: "It was a perfect trip but I was on the best horse. I was trying to be nice to him. He's a lovely horse. He travelled around beautifully. He's a big, strong horse and it's only his third ever run. The ground was probably a bit too loose for him. They think a bit of the second and third, so hopefully it will be (a strong race)."
O'Brien was winning his fifth Chester Vase in the last eight years, including 12 months ago with subsequent Investec Derby hero Ruler Of The World.
Kevin Buckley , Coolmore's UK representative, said: "We are very, very pleased with that. He was a bit keen for a little stage, but Ryan got him into a nice rhythm and travelled into the race.
"Ryan was very happy with the horse. He's a fine, big type of animal and typical of a Galileo. To do that around Chester, we have to be pleased.
"It was only his third career start and Aidan was happy with him at home and was looking forward to seeing how he got on here.
"Aidan probably left a little bit of work on him, and as I said it was only his third start and we were very happy with way he went around Chester."
Sky Bet cut the winner to 20/1 from 40s for the Epsom Classic, spokesman Michael Shinners saying: "He ended up scrambling home but I liked the way Orchestra travelled through the race. He's likely to form part of the O'Brien raiding party for Epsom and seems likely to handle the track - while we know he stays the trip."
