Gai Waterhouse-trained and ridden by a hoop with three group 1 wins this year - on paper Kinnersley had plenty going for him before Sunday's Goulburn Cup.
And the topweight and $17 chance put egg on the punters' faces in winning the $100,000 feature mile in style over one of the best fields in the race's history.
Jockey Tommy Berry admitted he was shocked the gelding was sent out at that price, despite finishing last at Hawkesbury two weeks ago.
After a breakout season where he has established himself as one of Australia's best young jockeys, Berry was always confident the six-year-old would bounce back.
''I don't think anyone should send one of Gai's out at that price after only one bad run,'' Berry said.
''She can definitely turn a horse around and she wouldn't go down to Goulburn with a flicker's hope.
''Being an older horse now, Hawkesbury is a tighter track and the ground was a bit shifty.
''When they get on that ground they look after themselves and I think that's what he did.
''But today he had a beautiful run, box-seated and he sprinted quite well.
''It's good to see the old boy's still got some spring in his legs.
''She [Waterhouse] has always wanted to win the Goulburn Cup, especially now it's $100,000.''
Kinnersley ($17.40) beat Scream Machine ($9.10) by a neck, with Alma's Fury ($5.50) a half-neck further back.
Kinnersley has the impressive strike rate of six wins from 19 starts, and may target some listed races in Tasmania next.
''I won a listed race on him [Lord Mayor's Cup] last preparation,'' Berry said.
''He's a funny horse, if everything goes right for him he wins.
''He's not a horse that will win three in a row.''
Two of Berry's breakthrough group 1 wins have been for Waterhouse, and for the most part he's been in her good books.
But while his roller-coaster year has provided him with more ups than downs, he knows what it's like to get on her bad side.
Berry was replaced by Vlad Duric on board Fat Al in the group 1 Emirates Stakes at Flemington after his flight from Sydney was delayed.
It's an error in judgment he will ensure doesn't happen again.
''It was a big disappointment but it will only happen once. I'll make sure I fly down the night before from now on, or get an earlier flight,'' Berry said.
''[Jockey] Christian Reith keeps giving it to me because he told me to get an earlier flight and I didn't listen. He got there and I didn't.
''Gai was very good about it, actually, but I was more worried about seeing her once I got there than missing the ride.''
