With three runners in Sunday's $60,000 Wellington Boot, Wagga Wagga trainer Trevor Sutherland holds an undeniable hand in the two-year-old feature.

Sutherland will saddle up Power Alert (John Kissick), Supreme Lyne (Michael Travers) and Our True Matriarch (Anthony Cavallo) in the 33rd running of the event.

Sutherland has enjoyed previous success in the Boot, his only other starter Sin Sin Sin, ridden by Travers, winning in 2008.

Asked to single out his best chance, Sutherland deferred to a declaration used by the always upbeat Gai Waterhouse.

"I'll have to do a Gai and say I can trifecta the race," Sutherland said.

"Really, they have all been set for the race for a long time. I'm happy with the three of them.

"They've all drawn well and have done well."

Sutherland revealed all three have worked together.

"There's not much between them," he said. "There's a split match between Power Alert and Supreme Lyne and Our True Matriarch is a lot better than her form shows."

Power Alert was bred by Sutherland. He beat the three-year-olds on debut over 900m at Albury on October 27 and has had no luck since.

"(In the Black Opal) he got stuck five-deep throughout," Sutherland said.

"After taking off early he probably led them with 100 metres to go but the hard run had to tell. The run was full of merit."

Supreme Lyne, purchased at the Dubbo sales for $2750, has a lot of ability, Sutherland said.

"The idea was to give her one hit-out before the Boot and she won very easy in quick time at Corowa," he said.

"She has awesome cruising speed then she can find another gear when you ask her to step up."

Our True Matriarch, an $8000 Dubbo yearling purchase, was a last-start third to Supreme Lyne at Corowa.

"She got run off the track on the home turn and got unbalanced and one thing she will appreciate is 1100 metres," Sutherland said.
