As the shortest-priced favourite on `Finals Day' at Flemington faulted in the All Victorian Sprint Series Final, it was interstate visitor Nearest To Pin who capitalised to land his first stakes victory.

Adelaide-based Nearest To Pin ($13) defeated Le Bonsir as $1.60 favourite Vain Queen failed to show the same dash as in her dominant win at the track two weeks earlier, and came in fourth.

Nearest To Pin's half-neck success justified the late decision by his connections to nominate the four-year-old for Saturday's $150,000 event over 1200m.

Andrew Gluyas, who trains in partnership with Leon Macdonald, was surprised at the victory but said it was a reward for the gelding's consistency.

"We thought it was worth a shot," Gluyas said.

"His form was good. His winter racing has been excellent.

"We entered for a race in Adelaide and didn't enter him here originally, but he came in as a late nomination given the strength of the field in numbers."

Nearest To Pin had finished fourth and second in two of the series heats.

He settled in behind the speed in the slow conditions on Saturday as Vain Queen raced just behind leader Corsica Lad.

Glen Boss asked Vain Queen for her effort around the 300m mark but she was quickly overhauled by Le Bonsir ($12) on her inside who dashed to the front before Nearest To Pin got the better of him over the concluding stages.

Shanghai Warrior ($10) hit the line well to finish 1-1/2 lengths behind Le Bonsir in third with Vain Queen another length away.

Boss was at a loss to explain the performance of Vain Queen, who had won by 3/3-4 lengths at her previous start but did rise 4kg in weight in her first Listed race.

"She was going to win by two (lengths) and got beaten by three. I don't know what happened to her," Boss said.
