Gary Player has never been one to shy away from bold opinions, but his latest prediction might just be his most eye-catching yet. The 90-year-old golfing legend, who has 159 professional wins and nine major championships to his name, recently sat down for an appearance on the Vanity Index Podcast—and what he had to say is sure to get fans talking.

Player, one of only six men in history to complete the career Grand Slam, knows a thing or two about winning at the highest level. While he's been complimentary of stars like Rory McIlroy, he's also been known to offer some constructive—and sometimes critical—observations about other players. He's previously weighed in on Jordan Spieth's coaching decisions, and now he's turned his attention to another fan favorite.

When asked which current PGA Tour pro—with zero major titles to date—has the potential to one day complete the Grand Slam, Player didn't hesitate. "I think, Rickie," he said, referring to Rickie Fowler. But the praise came with a caveat. "But he also needs to have a swing change."

Player elaborated, noting that Fowler's swing is improving but still lacks certain fundamentals that all the greats have shared. "It's getting better, but there's certain things that all the superstars did when they swung the club... Unless you do that, you are struggling to win major championships without doing it."

The six-time PGA Tour winner has long been known for his meticulous approach to the game, and he didn't hold back in his critique of modern coaching. "It's frustrating for me to see that nobody's teaching them to do this, because so many of the coaches today are teaching some very crazy things," Player added. He pointed to the number of past major winners who are no longer performing consistently, suggesting that flawed fundamentals may be to blame.

For Fowler, a player with undeniable talent and a loyal fan base, this kind of endorsement from a living legend is both a compliment and a challenge. Whether he can make the adjustments Player recommends—and finally break through for that elusive major—remains to be seen. But if there's one thing Gary Player's career teaches us, it's that swing changes and hard work can lead to history.
