The three-year-old filly blitzed her heat at the Cowra Paceway last weekend, finishing at a mile rate of 1:58.7 while boasting a hugely impressive second section of 57.2s. 

Thurston is confident "Jazzy" will outclass her opponents on Sunday, expecting her to be well supported.

"I think she'll be pretty short," Thurston said.

"She finished in a quick time in the heat at a mile rate of 1:58.7 which I don't think was far outside the track record. 

"Her back section of 57.2 is very quick at Cowra," he added.

During a 13-start career Gotta Go Jazzy Jet, owned solely and handpicked by Thurston's wife Denise, has accumulated four wins and four minor placings for a touch over $30,000 prizemoney.

Gotta Go Jazzy Jet started her career in New Zealand before going under the care of Goulburn-based trainer Brad Hewitt for nine starts, producing two wins and two minors.

Thurston then prepared her for victory in the $12,000-to-the-winner Young Oaks on March 12, before second first-up at Young on May 14 then first at Cowra last start. 

Following Sunday's Jack Honan Memorial Final, the team will relocate to Queensland where Thurston is targeting three races during Queensland's Winter Racing Carnival - Breeders Crown Heats (June 24), Gold Coast Oaks (July 2) and Queensland Oaks (July 9).

Thurston highlighted the filly's potential by explaining her performance in the NSW Oaks at Menangle on February 28, where she finished sixth behind the unbeaten Our Dream About Me.

"We're going to have a crack at all three," Thurston said.

"She finished sixth in the NSW Oaks and she was unlucky, she ran home with a quicker sectional than the winner. She would have been right in the NSW Oaks if she didn't get caught up and had a good run from the start.

"But I think she's improved now, she's certainly an exciting filly," he said.

Ahead of Sunday's final, Thurston said he's hoping to secure the services of Miracle Mile winning driver Mat Rue, who was in the gig for Gotta Go Jazzy Jet's heat win. 

"Mat's probably booked for a couple of drives [in the final] but he indicated to me at Cowra that the preference would be Jazzy," Thurston said.

"He's obviously realised the potential of her and I'm sure he's happy to jump on board a filly of her quality when he has the opportunity.

"He said she had some in reserve. She should win it, she's worked superbly this week."

Sunday is a full TAB event, seven race program with the first race set for 1.17pm.

Thurston has had an excellent weekend, with Freedom Is winning a heat of the Menangle series at Young on Friday afternoon. 

Freedom Is now competes on Saturday night in the $25,000 final.
