Brick By Brick made a bold bid from the front, but Golden Spell began to wear him down on entering the final furlong.
However, as befitting a man at the top of his form, Colin Keane - who is embroiled in a terrific tussle with Pat Smullen to be crowned champion jockey - got Gobi Desert (3-1) rolling to give Ger Lyons another decent prize. Brother Bear was the unplaced favourite.
Lyons said: "He hated the ground. Colin blamed himself the last day for riding him too prominent, but rode him the way he wanted to today.
"You have to ride him cold, but he's a seven-furlong minimum horse on better ground. I should think that will be his final run (this year) and hopefully we will hold on to him. He will be a nice horse next year on better ground going further.
"All he did today was stay, he was as green as grass, hated the ground. You couldn't have been more negative and the only positive thing we can say about the experience is that he won."
