England’s Sam Horsfield saw off Ryan Fox in the last round at Rinkven International Golf Club, to finish just a couple of shots ahead of the New Zealander.
The Soudal Open win in Belgium, now makes Horsfield a three-time winner on the DP World Tour. Horsfield first won on the DP World Tour at the Celtic Classic in 2020.
The latest win has shifted Horsfield up to seventh in the DP World Tour rankings.
An emotional Sam Horsfield said: "I was trying not to cry while I was over that little tap-in (at the 18th). Having Issi (Isabella Byron) on the bag, it's been an amazing week. Mick (Seaborn, his regular caddie) is not here but I wish he was. I said yesterday I wanted to do it for him, and I was able to do it for him. I'm just so, so happy.
"I definitely thought about Mick quite a lot. Especially on the back nine, I pulled a few clubs that he definitely would have wanted me to hit.
"Issi has been amazing. I've been so happy on the golf course. It's just like golf's sort of got in the way this week, until a little bit there on the back nine. I asked her coming down 18 'are you nervous' and she said yeah. But we've had an amazing week and I'm just so happy that she was here to enjoy this.
“This was a really special week for me, you know Issi my girlfriend was caddying for me, so it was a little different out there and we had a hell of a lot of fun. Unfortunately Mick my caddie couldn’t be here, you know I wish he was, and I was definitely thinking about him today. And this was for him.
“We just had fun all week, sort of like golf got in the way a little bit, you know we were having a blast out there chatting about everything that we could chat about and hit some golf shots in between.
“When I birdied 12 that was a huge bounce back birdie for me. My only bogey of the day was on 11 and to get a birdie right back and I think Ryan bogeyed the next hole, and I think we were all square from there. And then we had a huge put on 17 there and then just made par up 18.
“It is kind of funny, I feel like I have been playing really well but I haven’t been able to put four rounds together and this week I was able to do that, so knowing that it’s in there and that I can do it, it puts me in a good step forward for next week.
"This week I played solid all week and next week the US PGA, I'm really looking forward to it and definitely the summer ahead.”
