Lydia Ko
“As the inaugural Grant Thornton Invitational champion alongside Jason Day, I love seeing how Grant Thornton has brought the two tours together and has broken down barriers. I’m excited for what's ahead.”
Lydia has been one of the brightest stars in women’s golf for more than a decade. Born in New Zealand, Lydia won her first LPGA event at just 15 years old, reaching World No. 1 by 17. But she hasn’t stopped there. Lydia is a three-time Major Champion and 22-time LPGA winner—recently winning Gold at the 2024 Paris Olympics. In 2023, Lydia won the inaugural Grant Thornton Invitational alongside fellow Grant Thornton ambassador, Jason Day. As a leader in her sport, she continues to inspire the next generation with every game.
Jason Day
“Showcasing the pursuit of excellence side-by-side in a team event allows the world to see how strong the game of golf is.”
Jason is a global golf star and a 13-time PGA TOUR winner. Known for his distinct style on course, he is originally from Beaudesert, Australia, and is best known for his 2015 PGA Championship victory and his World No. 1 ranking during his incredible run that same year. A PLAYERS Championship winner in 2016, Day also recently won the 2023 Grant Thornton Invitational with fellow Grant Thornton ambassador, Lydia Ko. Off course, Jason is the proud father of five children and husband to his wife Ellie, as well as a passionate supporter of the Brighter Days Foundation.
Tony Finau
“We share a vision for bringing more people to the game and are passionate about working to improve the communities that we live in.”
Tony is an accomplished professional golfer from Utah who plays on the PGA TOUR. He has earned six wins on TOUR, competed in three Presidents Cups and two Ryder Cups since turning pro in 2007. When he’s not competing at the highest level, Tony is focused on giving back to his community and changing lives through the Tony Finau Foundation. Through his impactful charitable work, Tony gives back to underserved neighborhoods like the one he grew up in, equipping children in those communities with the educational and recreational resources, as well as support they need to discover, develop and achieve their goals. The first PGA TOUR player of Tongan and American Samoan descent, Tony lives in Lehi, UT, with his wife and five children.
Lilia Vu
“I want to inspire women and girls to embrace golf—to feel confident on the course—and showcase the strength of the women's game next to the PGA TOUR players.”
Lilia has quickly made her mark on the professional golf scene in recent years and is now one of the most exciting young stars in the game. A PAC-12 Player of the Year at UCLA, Lilia won two Major Championships in 2023, eventually earning a World No. 1 ranking and being named one of the LPGA Tour Players of the Year. Now a five-time LPGA champion and 2024 Solheim Cup winner with Team USA, Lilia looks to continue her success on course with Grant Thornton and continue to push the boundaries of the game.
