The final major of the year begins on Thursday in South Wales, as 145 of the best female golfers in the world tee off at Royal Porthcawl for the 2025 AIG Women's Open.
The opening odds for the major revealed a unique sight: England's Lottie Woad (5/1) serving as the favourite over Nelly Korda (11/1) and Jeeno Thitikul (10/1), the top two in the world rankings.
Woad, the former top-ranked amateur, won her first pro tournament last weekend at the ISPS Handa Women's Scottish Open. She clearly also won over the hearts of bookmakers, who likely want to limit their liabilities with the Brit and Florida State graduate.
Other top contenders in the field include Minjee Lee (14/1) and Ariya Jutanugarn (22/1). Miyuu Yamashita, Hyo Joo Kim and defending Women's Open champ Lydia Ko (all 25/1) round out the top eight on the odds board.
Don't expect many competitors to have familiarity with Royal Porthcawl Golf Club. This will mark the first time the Women's Open has been held at this course, and for that matter the first time Wales has hosted the tournament at all.
A 7,137-yard par-72, Porthcawl often features sharp Atlantic Ocean wind gusts from the bordering Bristol Channel. It's a gorgeous course, but it can be lethal for players who struggle to keep their drives on-line in windy conditions.
Much like Royal Portrush, the Northern Ireland site of the men's Open Championship, Porthcawl has unforgiving fescue surrounding most of its fairways. Some context: after it hosted the 1995 Walker Cup, it was called "the course that tamed Tiger."

Odds correct at start of tournament, click links below to bet.
Lottie Woad (5/1, Bet365)
Call us bandwagon bettors all you want, but we can't get away from Lottie here. She's on a sizzling hot streak, coming off a win at the Women's Scottish Open last weekend, a T3 at the Evian Championship in her previous start, and a victory at the Women's Irish Open earlier in July. Could we be witnessing the rise of the next golf superstar?
She's certainly becoming the talk of the women's golf world in short order. Woad's all-around consistency against the best players in the world is a remarkable sight. She's clearly confident, cerebral and poised, all elements we have come to expect from Scottie Scheffler on the men's side. We're riding this hot streak as far as it will take us.
AIG Women's Open 2025 best value bet
Ariya Jutanugarn (26/1, Betfair)
Jutanugarn seems to be flying under the radar a bit, despite her consistently solid form nearly all season. She has top-10 finishes in three of the four major championships so far this year, including a T2 at the Chevron Championship a T7 at the Evian Championship.
The Thai star has a knack for performing well in the biggest moments, including past Women's Opens. She won the event in 2016, finished T4 in 2018, claimed solo sixth last year and rounded out the top 10 in 2021. She also has a U.S. Women's Open title to her name (2018), so she's a golfer you can trust at the highest level of the sport.
AIG Women's Open 2025 top long-shot bet
Julia Lopez Ramirez (117/1, Betfair)
How fun would it be if we ended up with Julia Lopez-Ramirez and Lottie Woad battling at the end of Round 4 of the Women's Open? The two former top-ranked amateurs in the world have moved from collegiate golfers to watch to professional golfers to watch, and every ounce of our fandom wants the Mississippi State alum to challenge Woad for this major championship.
Lopez Ramirez showed at the U.S. Women's Open that she's got the nerves to contend against the top stars of the game. The Spaniard entered the final round one back of the lead, and she ultimately finished in the top 20. She also finished T3 at last week's Women's Scottish Open, and she was T29 at the Women's Open in 2024. Consider her as a lotto-ticket outright pick or a solid 18/5 to finish in the top 20.

AIG Women's Open 2025 best bet to finish top 20
Akie Iwai (11/5, Bet365)
This might be our favourite value bet of the entire tournament. Iwai has been in solid form of late, finishing T16 at the Women's Scottish Open last weekend. She also performs well at this tournament each year, with finishes of T11 and T7 in 2023 and 2024, respectively.
Iwai's performance last year at St. Andrews, in particular, is what makes her an intriguing pick to finish in the top 20 at Porthcawl. The winds at the Old Course were howling, yet she shot a final-round 69 to bag over a quarter-million in winnings. Don't be surprised to see the Japanese phenom contending this Sunday, as well.
