An eagle on the par-five 16th has seen Asian Tour Qualifying School-bound Jordan Zunic claim The Jack title by one shot at Pokolbin on Wednesday.

The 26-year-old Sydney-based professional finished nine under (135) for the 36-hole tournament at Crowne’s Hunter Valley Golf Club.

His two-under effort on the third last hole saw Zunic leapfrog runner-up Mitchell Brown (136) into the lead from second at seven under.

Both players then had birdie opportunities on the final hole. Zunic lipped out a lengthy putt to seal the trophy for 2018 before Brown, playing in the next and penultimate group, missed a difficult chance to level proceedings.

“That [eagle] was the key to getting the win in the end,” Zunic said.

Zunic’s second-round, six-under 66 was this year’s best 18-hole score, adding to Tuesday’s three under.

The Woolongong-raised and now Cronulla-based player, who heads to Thailand for the final stage of Asian Q-School next week, said it was “special” to win The Jack’s 40th anniversary.

“I probably wouldn’t be where I am today without them [Jack and Jacki Newton] and playing all of those junior tournaments as part of the foundation,” Zunic said.

“It makes it even more special.”

Callan O’Reilly and Belinda Ji were next best on The Jack card at six under (138) while Andrew Dodt (139) was one stroke further back in fifth.

Jamie Hook, Matt Steiger (141), James Nitties, Nathan Green and joint overnight leader Blake Windred (142) rounded out the top charts.
