"It was a good run in the New Zealand Cup and he'd been working well leading up to this," Ormsby said.
"It's a big thrill, he's an honest horse and getting back out to the two miles again suited him."
Mister Impatience settled into the trail and challenged early in the run home only to be clearly headed by Pentathlon.
"He got a beautiful trip and just lobbed along," successful rider Sam Spratt said.
"He dug really deeply when I threw everything at him and he is a true stayer."
Mister Impatience rallied strongly along the fence in the closing 100 metres to earn a nose victory over Pentathlon, who looked set for the thick end of the stake when he took control 300 metres out.
Pacemaker Sampson fought on doggedly for third while the favourite Jimmy Mac was unable to make any impression in the straight and finished sixth.
