Zaidpour upset the odds on favourite Voler La Vedette to take the Grade Two John Mulhern Galmoy Hurdle at Gowran Park.
Ruby Walsh was seen to great effect as he dictated the pace on the eventual winner and had everything in trouble going down to the last. Voler La Vedette put in a strong challenge, but was always held as Zaidpour won by a length.
The pair pulled a long way clear of Chicago Grey, who was third of the five runners.
Walsh said: “I didn’t know whether to go slow in front or follow her (Voler La Vedette).
“I’d given her a lead the last twice and she swept past and I thought she might do the same again.
“It was clear at the start no-one was going to make it (the running), so I sauntered along in front.
“He just loves soft ground – you couldn’t have it soft enough for him.”
Mullins added: “The tactics and ride won it for him. Ruby gave him a very sharp ride. I don’t know where he’ll go at Cheltenham, the Champion or the World Hurdle.
“Today’s race wasn’t a trial for either race as they went no gallop but his connections would like to run at Cheltenham. That’s his ground.”
