The race complexion changed at the second last as well-backed even-money favourite Un Beau Matin (from 6/4) crashed out.
The winner had finished runner-up to Un Beau Matin on his last outing at Punchestown last month.
"He really deserved that. If you look back through his form he has never run a bad race," said Fahey.
"He'll probably only have one or two more runs this season as I can't wait for next year over fences - he's a brilliant jumper.
"I'd say the plan will be to bring him back good and early over fences.
"Andrew gets on with him really well. He's not the easiest horse to ride and can mess around and whip around at the start.
"This was our Derby day today."
