An unresponsive putter prevented Cassie Porter from staging a Sunday charge as Kiwi Nick Voke held on just long enough to take out Webex Players Series Sydney at Castle Hill Country Club.

Trailing Voke by eight strokes heading into the final round, Porter needed everything to go her way to mount any kind of challenge.

She and coach Dan Morrison forgot to tell her putter, though, fighting back with three late birdies for a round of even par 72 and a share of 13th.

Scheduled to resume her rookie season on the LPGA Tour in two weeks’ time at the Blue Bay LPGA in China, Porter can take confidence from a ball-striking week that yielded rounds of 65 (Round 1) and 63 (Round 3).

A birdie at the first was a promising start on championship Sunday yet bogeys at two, six and seven would effectively end any winning aspirations.

The 22-year-old reached her arms to the skies after a birdie putt found the bottom of the cup on 10 but again dropped down the leaderboard with bogeys on 12 and 13.

Despite her earlier struggles, Porter finished the week with birdies at 14, 16 and 18 to generate some positive momentum moving forward.

Fellow Queenslander Justice Bosio had two birdies and 16 pars in her round of 2-under 70 to finish in a tie for 32nd along with New Zealand’s Momoka Kobori, whose brother Kazuma was the champion at Castle Hill in 2024.

Voke’s win made it two straight for the Kiwi contingent not only at Castle Hill but on the Challenger PGA Tour of Australasia following Josh Geary’s Vic Open triumph.

Leading by four overnight, Voke kept Queenslander Jake McLeod at bay for most of the round until a late switch in momentum.

Leading by five with five to play, Voke dropped a shot at 14 and McLeod made birdie on 15. After taking iron off the tee at the short 16th, Voke hit his approach left of the green and had to make a putt from five feet to avoid making double bogey.

The tenacious McLeod, who has been knocking on the door of a win all season, then converted his birdie chance from 15 feet and suddenly Voke’s advantage was just one heading to the 17th tee.

A superb tee shot gave McLeod another look at birdie at the par-3 17th but his 12-foot putt just slipped underneath the right edge as Voke again needed to make a clutch par save to stay one in front playing the 72nd hole.

With persistent rain dousing the final group, both players had 78 metres into the par-5 finisher for their third. Voke almost flew his shot into the hole before it release to the back edge as McLeod’s came to rest 15 feet short and right of the hole.

After Voke putted down to a foot, McLeod had a putt to force a playoff, his birdie attempt hanging agonisingly on the right edge, leaving Voke to merely tap in and claim victory.
