What Golfers Are Close to a Career Grand Slam?

By Spencer Lanoue
November 1, 2025

Winning a major championship solidifies a golfer’s place in history, but winning all four is a direct ticket to immortality. Achieving the Career Grand Slam is golf's most formidable challenge, a mark of sustained excellence across vastly different types of courses and conditions. We’re going to look at the living legends who are just one trophy away from joining the most exclusive club in golf, and what exactly stands in their way.

What is the Career Grand Slam?

First, let’s get on the same page. The modern Career Grand Slam means winning the four professional major championships currently in rotation during a player's career:

  • The Masters Tournament
  • The PGA Championship
  • The U.S. Open Championship
  • The Open Championship (often called the British Open in the States)

It's a test of complete mastery. Winning The Masters requires navigating Augusta National’s extreme slopes and lightning-fast greens. The PGA Championship often tests power and precision on long, demanding parkland courses. The U.S. Open is a brutal examination of accuracy and mental fortitude, with its punishing rough and tight fairways. And The Open Championship demands creativity and ground-game genius on firm, windy links courses. To win them all shows a golfer has no weaknesses.

Who Has Achieved It?

To understand the magnitude of this feat, just look at the list of players who have accomplished it. There are only five:

  • Gene Sarazen
  • Ben Hogan
  • Gary Player
  • Jack Nicklaus
  • Tiger Woods

That's it. Some of the greatest names in the sport's history - Arnold Palmer (needs the PGA), Tom Watson (needs the PGA), Lee Trevino (needs The Masters) - never managed to grab all four. It's a club with a velvet rope and a bouncer who doesn't negotiate. Right now, three active players have an invitation in hand, but need to pass that final, gut-wrenching test.

The Contenders: Three Players on the Brink of History

Three modern greats are knocking on the door. Each has won three legs of the slam, but each has a particular demon they must conquer to complete their career-defining quest. Let's break down who they are, what they need, and what’s holding them back.

Jordan Spieth: Needs the PGA Championship

When Jordan Spieth burst onto the scene in 2015, capturing both the Masters and U.S. Open, it felt inevitable that he would become the youngest ever to complete the slam. He added The Open Championship in a spectacular finish at Royal Birkdale in 2017, bringing him to the very edge of history at just 24 years old. All that remains is the Wanamaker Trophy of the PGA Championship.

The Obstacle: Finding Consistent Ball-Striking on Demand

So, what’s the holdup? While Spieth has a top-3 finish at the PGA to his name, the tournament has proven to be his most difficult puzzle. PGA Championship venues are typically long, demanding "big-boy" golf courses. Harding Park, Southern Hills, Valhalla, Oak Hill - these courses reward pure power and tee-to-green prowess, an area of Spieth’s game that can sometimes be streaky.

During his peak, Spieth's iron play was supernatural and his putter was a magic wand, allowing him to overcome any inconsistencies with his driver. But when his tee-to-green game is slightly off, these demanding PGA setups don't offer the same bailout opportunities as, say, Augusta National, where his otherworldly short game and creativity can save him. PGA courses are far more penal for wayward drives, and when you can't rely on finding fairways, it’s tough to score.

A Coach's Perspective: The Path to Victory

For Jordan to finally lift that Wanamaker Trophy, it all starts on the tee box. He doesn't need to lead the field in driving distance, but he must find a level of fairway-finding consistency that allows his greatest weapon - his iron play and putting - to shine. In the pressure-cooker of a final round, you can't be scrambling for par on every hole. When Spieth drives the ball well, he's arguably one of the best in the world. He just has to make sure that version of himself shows up for four straight days in May.

Rory McIlroy: Needs The Masters Tournament

Rory McIlroy has been on "Masters Watch" for what feels like an eternity. After famously blowing a four-shot lead on the final day in 2011, he re-tooled his game and mindset to rattle off four major victories in a breathtaking four-year span: the 2011 U.S. Open, the 2012 PGA Championship, the 2014 Open Championship, and the 2014 PGA Championship. Since then, the only thing missing from his trophy case is a Green Jacket.

The Obstacle: The Ghosts of Augusta

Ironically, McIlroy’s game - a towering, left-to-right ball flight off the tee - is so theoretically perfect for Augusta National it's almost cruel. Watching him on the range, you’d design the course around his swing. But golf, especially at Augusta, is played between the ears.

Every April, the storylines begin and an entire career’s worth of pressure mounts. Every missed three-footer isn't just a bogey, it’s a sign that "the narrative continues." Every hole, from the risk-reward 13th to the treacherous 12th, carries the weight of past disappointments. Rory’s struggles at Augusta aren’t about physical skill. It’s about being able to play with the freedom he exhibits at other majors, without the baggage of needing this one victory to complete his legacy.

A Coach's Perspective: The Path to Victory

The key for Rory isn't to hit his driver higher or his irons closer. It's to build a tactical game plan that mitigates risk and lessens the pressure. He needs to trade "spectacular" for "smart." He possesses the power to eagle both par-5s on the back nine, but the Green Jacket is often won by avoiding double-bogeys, not by making eagles.

If he can adopt a strategy of playing to the heart of greens, taking par as a victory on the toughest pins, and leaning on his streaky-good putting, he can let his immense talent put him in position without forcing the issue. He needs one quiet, drama-free, "boring" Sunday at Augusta. If he can achieve that, he’ll find the silence he needs to finally slip into that green jacket.

Phil Mickelson: Needs the U.S. Open

Of all the active players on this list, Phil Mickelson’s chase for the Career Grand Slam is the most famous and, frankly, the most painful. With three Masters, two PGA Championships, and an Open Championship Claret Jug, Phil has proven his Hall of Fame credentials many times over. The one that got away? The one he's finished runner-up in a record-shattering six times? The U.S. Open.

The Obstacle: A Style Clash with U.S. Open DNA

The U.S. Open is designed to be the toughest test in golf. USGA setups are famous for narrow fairways, thick, unforgiving rough, and lightning-fast greens. In short, the tournament rewards discipline, precision, and risk aversion. And "risk aversion" is simply not in Phil Mickelson’s vocabulary.

His legendary, go-for-broke style, affectionately known as "Phil the Thrill," is the very reason we all love him. It's also the exact thing the U.S. Open is designed to punish. From his heartbreaking double-bogey on the 72nd hole at Winged Foot in 2006 to a half-dozen other close calls, we've seen his aggressive nature betray him on the one stage that demands conservatism. He wants to hit bombs and flop shots, the U.S. Open wants you to hit fairways and two-putt for par.

A Coach's Perspective: The Path to Victory

For Phil to win, it would require a fundamental reinvention of his on-course philosophy for 72 holes. He would need a week where he commits to hitting irons off tees, prioritizes finding the short grass over getting a few extra yards, and plays for the center of every single green. It's like asking a lion to eat salad for a week. While his historic PGA Championship win in his 50s proved he can still find lightning in a bottle, overcoming his inherent nature in the face of the U.S. Open setup would be his most impressive feat of all.

The chase is what makes this so compelling. Each of these incredible players has proven they can beat the best fields on the hardest courses. Now, they just need to conquer their final summit, a single tournament that, for one reason or another, seems to have their number.
