Former Open Championship winner Louis Oosthuizen has become the latest high-profile player to quit LIV Golf, describing it as the “hardest decision he has had to make in his career”.

The league filed for Chapter 11 bankruptcy protection in the United States in September after Saudi Arabia’s Public Investment Fund withdrew its multibillion-dollar backing.

Oosthuizen, 44, joined LIV Golf in 2022 and was captain of the Southern Guards GC team.

The South African now plans to return to the DP World Tour in 2027.

“Five years ago, I made one of the best decisions of my life, moving away from the traditional golf world and into something very special with LIV Golf and Southern Guards GC,” Oosthuizen posted on social media.

“I’m the biggest supporter of team golf and always will be. Golf needs more of it.

“This is probably the hardest decision I’ve had to make in my career, but I have to do what I believe is right for my golf.”

The 2010 Open champion, who has finished as a runner-up at least once in each of the other three majors, said a more flexible playing schedule will help him to compete at a high level.

“I realised I have a lot more in me, and my biggest fear was that the schedule on LIV 2.0 would be tough to manage,” said former world number four Oosthuizen.

“I feel I have a few more years of good, competitive golf left in me, and the only way to be really sharp and competitive is through a schedule I control.”

Oosthuizen joins Thomas Pieters, Sergio Garcia, Abraham Ancer, David Puig and Adrian Meronk in announcing his departure.

Last week, two-time major winner Jon Rahm gave up a reported £75m owed to him by LIV Golf after reaching a separation agreement.

Some former LIV Golf players, including Brooks Koepka, have since rejoined the PGA Tour, which rewrote its rules in December to allow the five-time major winner to return, subject to certain sanctions.

Guy Kinnings, CEO of the DP World Tour, told BBC Sport earlier this month that players who continue with LIV will not be allowed to be members of the European tour next season.

LIV has secured a possible $300m (£224.2m) in financing from BC Partners Credit in order to try to move forward with the 2027 season.
