The Englishman held a one-stroke lead after Monday’s level-par 72 on the West Course, despite having opened the tournament with back-to-back bogeys.
Popert’s double-bogey on the sixth hole during the final round saw Lawlor and Englishman Mike Browne move into contention as all three shared the lead on the tenth hole. But Popert hit back with four gains on his back nine, including a birdie on the famous 18th hole, to card a three under par 69.
The win is Popert’s third in the space of five months, adding to his successes at the G4D @ Betfred British Masters hosted by Danny Willett and in Germany.
“It feels really good, to hole that putt on the last was nice,” said Popert. “It meant a lot. The ball just went in the hole. I’ve been playing really well, today I didn’t play nearly as well as I did yesterday – my iron play was much better yesterday.
“I saw we were all tied coming into the back nine and I had to do what I needed to. I was really pleased and Ben, my caddie, has been brilliant. We’re really getting somewhere and we’re really working well together.
“My friend Kiera lives really near here. I always drive past the gates (of Wentworth). It’s really cool to win and it’s only an hour or so from my house. I had my dad and a few uncles here, so that was cool.
“Over that putt on the last… my cousin passed away three years ago. He was a professional rugby player, made his debut and then passed away that night. I just do this for him – we both used to motivate each other and over that putt, that’s who I was thinking of. It went right in the middle. I treasure the shots I get to hit and I do it for the people I love.”
Lawlor recorded his second runner-up finish of the season, finishing level par after a one-under second round, with Browne taking third place on three over par.
Popert is one of three players already confirmed for the G4D Tour Series Finale @ DP World Tour Championship, and will be joined in the field by Browne, who won G4D @ Horizon Irish Open, and Italy’s Tommaso Perrino, who won G4D @ ISPS HANDA World Invitational presented by AVIV Clinics.
The winner of the next event, G4D @ Estrella Damm N.A. Andalucía Masters, will also join them in the field, with the remaining six spots spots allocated based on performances during the inaugural G4D Tour season.
