Thompson's 51^st birthday was capped with another country cup on Wednesday when his two-year-old star stunned hot favourite Simon Told Helen.

Zambora Smokey, whose sire Zambora Brockie secured the Warrnambool Cup in 2016, jumped first and held off a late rush home to secure the $31,500 prize.

Thompson, based near Frankston, said the 626-kilometre round trip to Warrnambool was a May highlight.

"It's a great birthday present," he laughed.

"It's a long drive home but it'll be enjoyable. We came here hoping to win one race and that was hopefully the cup."

He said Zambora Smokey's fast start laid the foundations for the cup victory.

"We knew he had to do what he did tonight, jump and potentially lead but didn't think he'd be able to do it because (Simon Told Helen) is a class dog," Thompson said.

"I thought if he jumps and leads we wouldn't be able to run it down again this week with the benefit of the run that it had last week.

"It probably missed it a bit and we led and it just went to script the way we wanted."

Three of Thompson's runners - the others Hooked On Scotch and Fire Legend - broke the revered 25-second mark over 450 metres to complete a treble for his kennel.

Hooked On Scotch won the time-honoured Stan Lake Memorial.

Thompson said Zambora Smokey would tackle the Victorian country cup circuit before a stint in Melbourne.

Dennington's Ray Drew, who trains in partnership with son Dustin, continued his streak of winners on Warrnambool Cup night with Lektra Yoyo.

The Drew family, who train less than 10 dogs, have had winners on the last five cup nights at Wannon Park.

Lektra Yoyo came from behind to stun Broken Drum by a neck in a speedy 25.29 run over 450 metres.

Drew said Lektra Yoyo - who crossed to his kennel two weeks ago - was responding to more individual training.

"He's come from a big kennel down to a small kennel, which probably suits him," he said. "We haven't done anything different to what he's used to. There's been no mysteries about him."

It was Lektra Yoyo's second-successive and fourth overall win.

South-west chasers had a field day early on, with the Peter Keane-trained Hello Keen producing a blistering 21.97 run in the opening race to break its duck.

Penshurst trainer Kayla Bunworth's Abalone Fozz was also too strong in the second of the night.
