No matter how big your lead is heading into the final round of a Championship there is still that question of what if?

John BoultonAhead of the final round of the $20,000 ADH Club Car WA PGA Trainee Championship, John Boulton had to sleep on a 13-shot lead but quickly changed the what-if to by how many at the start of round four.

Perth and Wembley Golf Course produced another stunning golf day for the last round of the Championship where Boulton produced the most dominant performance seen in a PGA event for some time.

The Mount Lawley Golf Club Trainee led from start to finish to win by a massive 15 shots at 20-under the card.

Vowing to keep it simple after his opening round of 67, Boulton made the game of golf look easy in his following rounds of 66, 66 and 69 for a 268 tournament total.

“I’m so happy with the result, it was an awesome week and to win by that many is amazing,” Boulton said.

The WA local knocked all negative thoughts over the big lead out of his mind from the get-go to try and relax and enjoy the final 18-holes.

“The mind plays funny games with you and to come out and eagle the first hole of the day to shut down any thoughts down was great.

“Thanks to Grant Hill from ADH Club Car for sponsoring the event and Wembley Golf Course for hosting, the course was absolutely fantastic.”

After a stellar third round, Jeong Woo Ha claimed second place for the tournament overall with rounds of 71, 74, 67 and 71 for a 5-under 283 total.

WA Trainees Luke Gerrard, Ethan Andrews and last year’s winner Dale Howie tied for third place at even-par for the tournament.

Boulton will now be hoping to take his fine form to the $60,000 National Futures Championship in Ballarat, Victoria next month.
