2025 AIG Women’s Open betting tips: Our expert’s top picks at Royal Porthcawl

Expert selected AIG Women's Open betting tips from Today's Golfer.

Tom Jacobs picks out his top AIG Women’s Open betting tips ahead of the final major of the year.

The season’s final major gets underway this week from Royal Porthcawl in South Wales, where 144 of the best players in the women’s game look to secure themselves a place in the history books.

Mao Saigo, Maja Stark, Minjee Lee, and Grace Kim have scooped the first four of this year’s biggest prizes…can any of them make it a double-winning major season? Lydia Ko goes off at 25/1 to reclaim the title she won at St Andrews 12 months ago, with Jenno Thitikul, Nelly Korda, and Minjee Lee fancied more, all hovering around between 10/1 and 14/1.

The bookmakers’ favorite, though…Lottie Woad, making just her second start as a professional. The Englishwoman tees off as a 6/1 frontrunner to make it two from two, by backing up her Scottish Open victory last week.

We’ve had some good success across the men’s majors this year, now let’s see if we can make some money on the Welsh coast. Here’s where I think you can find value this week!

2025 AIG Women’s Open betting tips:

The Longshot: Nanna Koertz Madsen 100/1 e/w (bet365 5 places 1/4)

Nanna Koertz Madsen is not among the elites in this field, but in 2022, she became the first Dane to win on the LPGA, and she’s held her own in this event in the past, making her an intriguing prospect after last week’s effort.

Madsen finished 6th last week, but was 2nd going into the final round and never sat outside the top 7, so it was a very promising week for someone who doesn’t win often. This effort last week added to her fantastic performance at the Meijer LPGA Classic four starts ago, where she was the 54-hole leader, eventually settling for a strong 4th-place finish.

She has struggled in her two major starts in between, but the Evian Championship in particular has never been a good event for her, so I am not too worried about that. Instead, I am more intrigued by Maden’s performances in this event, both in 2021 when she finished 5th, and last year when she finished 10th.

When 5th in 2021, she was the 54-hole leader, as she co-led with eventual winner Anna Nordqvist. While you could argue the pressure got to her, she only lost out by two shots, and this was at a time when she hadn’t yet won on the LPGA Tour. Now more experienced and likely playing with a bit more belief, I think she could come out on top if she finds herself in a similar situation this time around.

Her 10th-place finish last year was a bit more pedestrian as she grew into the event instead, but it was another good sign, and she now comes into this event with a really strong finish in Scotland last week, and another close call on the LPGA Tour.

The Outsider: Ariya Jutanugarn 30/1 e/w (Bet365 5 Places 1/4)

Ariya Jutanugarn has been around for a long time, but at 29, she still has plenty of time ahead of her to add to a major haul, which currently sits at two. One of those came in this event back in 2016, just a year after she joined the LPGA for the first time, and three years after turning pro.

Jutanugarn has won plenty and did so quickly after turning professional, but she’s now in a four-year drought, something that was cruelly accentuated when duffing a chip on the final hole of the Chevron Championship. She had a one-shot lead at the time and would have won a third major title, had she gotten up and down. Instead, she made a bogey six. The good news is, she’s bounced back very well from disappointment, with four top 10 finishes in her last six starts, including when 8th in Scotland last week.

Three top-9 finishes in four major starts this season, Jutanugarn has been a consistent performer in the biggest events this year, and now returns to her favourite of the lot. In addition to her 2016 victory in this event, she has three more top 10 finishes and an 11th in the Women’s British Open, and that stands her in good stead given the likes of Lydia Ko, Ashleigh Buhai, and Anna Nordqvist have all won this in the last five years. Clearly a veteran presence has been useful here, and Jutanugarn can turn heartbreak into joy this weekend in Wales.

Jutanugarn ranks inside the top 20 in both SG Approach and SG Tee to Green on the LPGA this season, with her putting (61st) largely the difference between her contending and winning. As a player with incredible links pedigree, though, we could see a better putting week just like we did last week, when she ranked inside the top 16 for both Putting Average and Putts Per Round.

The Banker: Angel Yin 22/1 e/w (Bet365 5 Places 1/4)

Angel Yin’s major form is trending in the right direction this season, as is her form at this event, and that makes for the perfect recipe at Royal Porthcrawl this week.

In 2025, Yin finished 13th at the Chevron Championship, 9th at the US Women’s Open,  6th at the Women’s PGA Championship, and 5th at the Evian Championship. While she hasn’t been right in the heat of the battle at each of them, she led after round 1 of the U.S. Women’s Open, and was in the mix at halfway of the Chevron Championship, sitting just two back going into the weekend.

Yin hasn’t been able to stay in the hunt at these four majors so far this year, but she does have previous, having lost out in a playoff in the 2023 Chevron Championship and finishing 2nd at the U.S. Women’s Open in 2019.

What is really eye-catching for me, though, is the fact that not only has she been so consistent in the majors this season, finishing inside the top 10 in more than one major in a season for just the second time in her career, but the fact that she’s clearly getting better at the Women’s British Open.

She missed three of her first seven cuts in this tournament, failing to crack the top 10 (11th her best finish), but over the past two years, Yin seems to have cracked the code with a 6th in 2023 and a 10th last year. When 6th two years ago, Yin had a chance to win sitting 3rd going into Sunday, sitting one back of Charley Hull and Lilia Vu. She fell away on the Sunday, but it was her first chance of winning this title, and she clearly took that confidence into last year, improving every round after a very slow start. Yin grinded all week to go from 118th on day 1, 60th on day 2, all the way into the top 10 after a great run over the final three rounds.

Given the incredible form in the majors this year, where she’s finished better every time she tees it up, and the fact that she doubled her LPGA win tally earlier this season, Yin looks a good prospect in this week’s Women’s British Open.
