Golf's Grand Slam: Who Will Complete the Remarkable Achievement Next?
The 2025 Masters Tournament will go down as one of the most memorable in recent history, as Rory McIlroy defeated Justin Rose in a playoff and completed the career Grand Slam. Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus, and Tiger Woods are the only other golfers in history to win each of the four major championships: the Masters, PGA Championship, U.S. Open, and The Open Championship. Many others have come close. Walter Hagen, Tom Watson, Sam Snead, Lee Trevino, Jim Barnes, Raymond Floyd, and Tommy Armour all won three of the four majors.
Woods was the last player to complete the career Grand Slam before McIlroy, winning The Open Championship in 2000. Will it take another 25 years for another golfer to win each of the four major titles? Here's a look at some golfers who could join the exclusive club of career Grand Slam winners in the near future.
Jordan Spieth
About one month after McIlroy made history at Augusta, Jordan Spieth had an opportunity to achieve the career Grand Slam at the PGA Championship at Quail Hollow in Charlotte, North Carolina. However, the three-time major winner was unable to recover from a first-round 76 and missed the cut by one stroke. This was his eighth attempt at completing the career Grand Slam, and he hasn't been particularly close. His best result was tied for third in 2019, six shots behind winner Brooks Koepka. He finished tied for second place in 2015, the same year he won the Masters and the U.S. Open.
Spieth equaled the record for the lowest round in Masters history with an opening round score of 64 in 2015. He led wire-to-wire and secured a four-stroke victory over Phil Mickelson. Following his second-place finish at the 2015 PGA Championship, Spieth, at 21, became the youngest U.S. Open champion since Bobby Jones in 1923. He finished tied for fourth at The Open that year and won the event in 2017.
Scottie Scheffler
Before the 2025 season, Scottie Scheffler had won just one of golf's four Grand Slams, but the two-time Masters champion might have the best chance at winning all four majors before anyone else. Scheffler completed the second leg of the career Grand Slam by winning the 2025 PGA Championship in dominant fashion, finishing five strokes ahead of second-place finishers Harris English, Bryson DeChambeau, and Davis Riley.
Scheffler had a breakthrough campaign on the PGA Tour in 2024, winning seven titles and the gold medal in the men's Olympic golf competition. He earned a record $29.23 million in prize money and finished in the top 10 in all but three of his 21 starts. He has kept up that pace in 2025, most recently defending his title at the Memorial Tournament on June 1, two weeks before the U.S. Open. Considering how dominant he has been, it wouldn't be a shock to see him win both the U.S. Open and The Open in 2025.
Phil Mickelson
Like Spieth, Mickelson has been waiting for quite some time to win the fourth leg of the career Grand Slam. However, time isn't on his side; he turned 55 in June of this year, whereas Spieth is still 31. A 45-time winner on the PGA Tour, Mickelson won the Masters three times (2004, 2006, and 2010), the PGA Championship twice (2005 and 2021), and The Open Championship once (2013).
Mickelson has come painfully close to winning the U.S. Open on multiple occasions. In fact, he was a runner-up at the major championship six times from 1999 to 2013. He hasn't come close since, missing the cut in five of his last 10 starts, including in each of the last three years.
While it's unlikely Mickelson can keep up with the current generation of golfers, the fact that he became the oldest major winner ever at the 2021 PGA Championship suggests another major title may not be out of the question.
Brooks Koepka
Brooks Koepka is a five-time major winner, but is still two majors away from completing the career Grand Slam. The 35-year-old American, now competing on the LIV Golf tour, was one of the best golfers in the world from 2017-19, winning the PGA Championship and U.S. Open twice. He won the PGA Championship for a third time in 2023.
Koepka still needs to win the Masters and The Open. He had a pair of runner-up results at Augusta in 2019 and 2023 and was tied for fourth place at The Open Championship in 2019.
Jon Rahm
Spaniard Jon Rahm also needs to win two majors—The Open Championship and the PGA Championship—but is still in the prime of his career at 30 years old. He was the first Spanish golfer to win the U.S. Open in 2021 and, two years later, won the Masters, overcoming a two-shot deficit through three rounds to beat Koepka and Mickelson by four strokes.
Rahm's best result at The Open and PGA Championship was T2 (2023) and T4 (2018), respectively.
