King Montrose led throughout 1200m against his own age group.
A gelding by King's Chapel from Dorrington, he was a $25,000 purchase at the 2008 select yearling sale at Karaka.
He is owned by Bill Rutherford, of Culverden and Burnham trainer, Neill Ridley.
Dorrington has left six other winners including Explosive Burst, a group one winner in South Africa.
Rutherford is also in the ownership of Beat It, an impressive winner at Riccarton this month at his only start.
The Michael Pitman-trained Beat It has been the subject of overseas interest. Jillian Morris, the rider of King Montrose, was suspended until midnight on September 3 for careless riding.
She checked Stopover in the early stages when moving across to the rail.
Gasnier, winner of the Riverton Cup in April, has joined the New Plymouth stable of John Wheeler.
Gasnier, previously trained by part-owner Daniel Champion at Ashburton, was spelled for two months after his last start in June.
Steven Kellow has made a good start since joining Kevin Hughes as a training partner this month.
They won an open sprint with Lil' Monster on a premier day of the Grand National meeting.
The partnership was successful yesterday with Baci, who ran his rivals ragged in a rating 80 1600m.
Kellow has worked for the Hughes stable at Riccarton for two years after 10 years with stables in England.
It was the fourth win for Baci, owned by Carol Marie, of Christchurch.
"She [Baci] is booked to be served by Falkirk this spring but that might change on her run today," Hughes said. Jockey Terry Moseley figured in his second dead-heat for first at Oamaru in three weeks when he rode Danz A Rook yesterday.
Judged Graeme Rowland could not separate Danz A Rook and Gioarchino at the end of 2200m.
Gioarchino was ridden by apprentice Zman Zulkifli, who lost his whip at the 250m.
Gioarchino made the pace with Danz A Rook three quarters of a length away on his outer.
Moseley rode Under Parr, who dead-heated for first with Lotus in the Oamaru Winter Cup on July 26.
Moseley (42), who rode his first winner, Nitty Gritty at Feilding in 1984, could not recall dead-heating for first in another race.
An old "firm" was back in business when Peter and Dawn Williams trained Pinch to win yesterday for John McCormack, of Christchurch.
McCormack has raced numerous winners, including Argyll who won seven races, including four in a row from the Williams stable in the 1989-90 season.
