What is the career Grand Slam in golf? Here's what you need to know about the toughest feat in golf ahead of the 2025 Masters Tournament.

Former Masters champions Jack Nicklaus, Gary Player and Tom Watson said on Thursday they believe Rory McIlroy will complete the career Grand Slam with victory at Augusta National this week.

Sarazen, one of the game’s early stars, won the 1935 Masters to complete his slam — long before the grand slam term was applied to golf. Hogan came next in the 1953 Open (the only time he played in the tournament). Player joined the fraternity with the 1965 U.S. Open title, and Nicklaus followed a year later in The Open.
