Ultimate Sniper left no doubt as to who was the premier horse of the 2019 Inter Dominion with a brutal Championship victory, sitting in the breeze throughout to cap a perfect series.

Trained by Mark Purdon and Natalie Rasmussen and driven by the latter, the All Stars continued an exceptional night in the $500,000 feature, when Ultimate Sniper became the first four-year-old since 1991 to sweep the series.

The victory was apart of the stable winning seven of the opening nine races, including a clean sweep of the trotting (Winterfell) and pacing Inter Dominion finals as well as an extraordinary performance by Another Masterpiece to win the consolation.

"We thought when the fields come out we could have a good night with a bit of luck," Rasmussen said. "This bloke (Ultimate Sniper) didn't have too much luck but he was good enough. We just can't believe it."

Nothing has come easy for Ultimate Sniper throughout the series and that didn't change in tonight's final, with expectations that he would waltz to the lead proving unfounded.

While the peg-line would ultimately settle A G's White Socks ahead of Mach Shard, On The Cards and My Kiwi Mate, Ultimate Sniper moved into the breeze with San Carlo on his back.

"I thought it could pan out like that, I didn't bustle him too early and he did all the work," Rasmussen said. "He relaxed so well and he's so kind and lovely, and then when I asked him he just had that kick left."

With a lap to go the three-wide line emerged with Chase Auckland followed by stablemates Cruz Bromac and Thefixer, with Ultimate Sniper nosing A G's White Socks by the turn and then it was a matter of could he hold the chasers?

Mach Shard emerged down the sprint lane and Thefixer was the best of those running on wide, but Ultimate Sniper had all the answers.

"He was tired on the line, he just didn't give up," Rasmussen said. "For a four-year-old to come out and do it the way he has done it, he's never had an easy run or anything, but he made his own luck. I'm just absolutely rapt with the horse.

"I've been so lucky to drive so many great horses, but this is really quite special tonight. For a four-year-old to go undefeated in a traditional series, all through the heats and the final, just a wonderful feat."

While the All Stars Racing team have had many a magical night, this was a particularly special one at Alexandra Park.

"They see Mark and I winning, they don't realise the crew behind it and the people involved - from the breeders to the preparers to the people at home getting them ready. All our staff ... they will just be thrilled to bits. It just touches so many people."

Of the TeamVic quartet, Cruz Bromac finished fourth, Sicario seventh, My Kiwi Mate ninth and San Carlo 11th.
