Tony Pike’s judgment was proved to be correct after The Bostonian backed up his long-shot Doomben 10,000 (1200m) victory by again downing the Australian sprinters in Saturday’s Group 1 $A700,000 Kingsford-Smith Cup (1300m) at Eagle Farm.

The New Zealand trainer was planning to hold back The Bostonian and run him second-up in the Group 1 Stradbroke Handicap (1400m) next month, but a brilliant trackwork gallop last Tuesday saw Pike change plans.

“His work was so good we decided to run him in the Kingsford-Smith. After all it is a Group 1 race with $700,000 up for grabs and we have got the lion’s share at $420,000 first prize,” Pike said.

Starting $41 in the Doomben 10,000, the Michael Cahill-ridden The Bostonian was sent out a $10 chance yesterday but maintained his excellent Queensland winning record with a three-quarter length margin over outsider Princess Posh. The James Cummings-trained Trekking was a nose away in third place.

Pike said The Bostonian, who won three starts in Queensland last year, would continue on to the Stradbroke Handicap, but he was mindful of the fact that the gelding would receive a weight penalty for yesterday’s Group 1 victory.

“I hope they are kind to us and we only get an extra kilo or so,” Pike said.

“The Bostonian really seems to blossom up here. David (owner Archer) and I have always intended to come back here this winter. A win in the Stradbroke would be the cream.” Pike added.

Bred and raced by Archer, The Bostonian has now won nine of his 16 starts, five of which have been in Queensland, seeing him accrue $1,251,130 in prize money.

The Jimmy Choux four-year-old is one of three named foals, all of whom have won, out of the winning Keeper mare Keepa Cheval, who is a half-sister to the 20-time winner King Mufhasa, who was also owned by Archer and whose glorious career encompassed 10 Group 1 wins and two New Zealand horse of the year titles.

Keepa Cheval has yet to produce a runner since foaling The Bostonian in 2014, but she foaled a colt by Haunui Farm shuttle stallion Iffraaj last year.

The Bostonian’s sire Jimmy Choux has relocated from New Zealand to Western Australian farm Rosalee Park Stud.
