First-up specialist The Bostonian maintained his unbeaten Queensland record and caused a big upset when he won the Gr.1 Doomben 10,000 1200m) on Saturday.

In a race of sensations, the favourite Nature Strip was slow to jump and went around three deep before finishing fourth.

The second favourite Osborne Bulls was also slowly away and ran his fifth straight Group One placing.

The Bostonian became the first kiwi galloper to win the Doomben 10,000 since My Axeman in 1983 when he got an inside run to beat the Osborne Bulls by a long head with another long head to Dollar For Dollar in third place.

The gelding has now won all five of his first-up runs and all four of his starts in Queensland.

Trainer Tony Pike and owner David Archer plotted to bring The Bostonian back to Queensland after he won three races, including the Gr.3 Sunshine Coast Guineas (1600m), during last year's winter carnival.

His early carnival had been disrupted by problems but Pike was impressed with the way he handled the Queensland tracks.

Pike flew to Australia this week to watch The Bostonian work after the gelding had arrived in Australia eight days go.

However, Pike had to return to New Zealand and left stable foreman Chris McNabb to saddle the horse in the 10,000.

"We will now probably head straight to the Stradbroke Handicap (1400m on June 8)," McNabb said.

"He was here mainly for it and he is a horse which does race well fresh."

"I had a nice run behind the pace but then it was a matter of getting a run," jockey Michael Cahill said

"This horse has been really good to me."
