Louis Oosthuizen’s incredible run of Open Championship appearances just hit a heartbreaking roadblock. For the first time since 2013, the 2010 champion has been forced to withdraw due to an injury. It’s a huge loss for the tournament, but in a classic golf twist, it opens a massive door for fellow South African player Aldrich Potgieter, who steps in to take his spot.

“Unfortunately, because of a back injury, I’ve had to make the difficult decision to withdraw from both the Open Championship and LIV Golf’s JCB event.” Oosthuizen took to social media to announce the news. “It’s incredibly disappointing to miss two events I always look forward to, but my priority is now to focus on my recovery and make sure I’m fully fit before returning to the competition.”

Louis Oosthuizen’s battle with his back is a frustrating, decade-long saga that has constantly threatened his career. It first became a serious roadblock back in 2013, which, not coincidentally, was the only other time he had to miss the Open Championship. That year, a brutal flare-up in his lower back, hip, and neck forced him to step away from golf for five months just to figure out how to live pain-free.

The issue flared up again at the 2014 WGC-Match Play Championship. On the 13th hole, Oosthuizen was seen lying on his back as his trainer attempted to stretch him out. “If I can commit myself to hit the shot, it’s not that bad,” Oosthuizen said back then. “But I can’t commit. My body is restricting me to go through the shot.”

To stay on course, the South African has had to manage his body meticulously. He famously began traveling the PGA Tour with his own custom mattress because one night on the wrong hotel bed could completely derail his week. While that level of care and his famously smooth swing bought him years of stability, his body finally hit its limit under the pressure of preparing for another major.

It’s a tough break for Louis, but it paved the way for an incredible twist of fate for one of South Africa’s brightest young talents. PGA Tour’s Aldrich Potgieter, just 21 years old, will now take his place at Royal Birkdale, getting the call-up after a whirlwind couple of days.

From first alternate to Royal Birkdale: Potgieter’s whirlwind call-up

Potgieter’s path to Royal Birkdale was a wild ride of near-misses. First, he fell just one agonizing stroke short of a guaranteed spot during a grueling 36-hole marathon at Dundonald Links, leaving him as the field’s first alternate. Refusing to just sit and wait, he doubled down by playing the Monday Last-Chance Qualifier. He put up another massive fight, closing with a solid even-par 70 to finish third, but missed out again as Joe Dean snatched the lone available spot with a 68.

Just hours after thinking his Open dreams were dead, Oosthuizen’s sudden exit handed the first alternate a ticket straight into the year’s final major.

The timing could not have been better for Potgieter. Potgieter has spent most of 2026 fighting to survive Fridays. Since 2025, he has missed 20 cuts in 36 starts. But majors have been especially unkind. Across six major starts since The Open Championship in 2022, he has missed the cut four times: twice at the Masters and twice at the Open Championship. Only a tie for 64th at the U.S. Open 2023 stands as his best result. The 21-year-old made his debut at the PGA Championship this year and recorded his career-lowest score.

The struggles in his life go beyond the leaderboard. Potgieter was born in Pretoria and moved to Perth when he was eight years old. He has grown his game around raw power long before he turned pro in 2023. He has also spent recent months overhauling his training and diet, dropping around 35 pounds as he adjusts to the change. It has also coincided with some of his better stretches this year. None of it guarantees a good week at Royal Birkdale, but for a player who has spent most of 2026 trying to survive weekends, walking into the major could be a huge opportunity.
