Tiger Woods and Jack Nicklaus are the two greatest golfers of all-time by just about the size of the universe. There is nobody else even remotely close to challenging the throne. So while golf features the closest two-player GOAT race in sports, the race for the third spot is wide open. There are no fewer than seven golfers who have a legitimate argument as the third greatest of all-time. It’s not hard to put together a compelling case for each, but there is plenty of evidence to suggest that Phil Mickelson has the best argument of the group. Among golfers born since WWII, only Tiger Woods (82) has more PGA Tour titles than Mickelson (45). In fact, besides Woods, only Tom Watson (39) is within 10 of Mickelson’s mark, and only Vijay Singh (34), Rory McIIroy (27) and Johnny Miller (25) are within 20. Mickelson’s case doesn’t just rely on being the most prolific golfer on the PGA Tour outside of Tiger Woods since WWII. His performance at major championships and The Players Championship (TPC) also supports his claim. Among golfers outside of Woods born since WWII, only Tom Watson (8) has won more majors than Mickelson (6). Watson is among the golfers who have a legitimate claim to the third spot, but Mickelson just might have a more impressive resume despite winning fewer majors. Mickelson won the TPC which Watson did not, and in the history of golf, nobody outside Nicklaus (37) and Woods (22) has more top-two finishes at majors than Mickelson (18). The same is true for top-three, top-five, and top-10 major finishes.

It’s clear that Mickelson’s competition for the 3rd spot really only includes Watson and people who were born prior to WWII when golf was nowhere near as competitive as it has been in the 21st century. Not only did Mickelson face the most competitive field the sport has ever seen, he had the misfortune of his peak coinciding with the juggernaut that was Tiger Woods. Watson, for all his accolades, did not have to contend with Nicklaus’s peak. Mickelson had no such luck as he landed smack dab in the eye of the Tiger storm. Yet, Mickelson still managed to outperform every golfer of the past 50 years outside of Woods. This is a significant advantage in Mickelson’s favor over the others in the running.  

However, it’s not just the degree of difficulty that gives Mickelson the inside track at the third spot, it’s how much more impressive he was than every other golfer outside of Woods from his era. Walter Hagen (1913), Bobby Jones (1916) and Gene Sarazen (1920) all debuted at majors within seven years of each other and have fairly similar career accomplishments. Ben Hogan (1934), Sam Snead (1937), and Byron Nelson (1937) all debuted at majors within three years of each other, and have fairly similar career accomplishments. Arnold Palmer (1952) and Gary Player (1956) debuted at majors within four years of each other and also have fairly similar career accomplishments. Outside of Tiger Woods, there isn’t a golfer who debuted in the last 50 years who is even in the same stratosphere as Mickelson. No golfer other than Woods in that span has more major championships, 2nd place finishes, or top-two finishes. In fact, nobody outside of Woods is even close. Mickelson has a whopping 18 top-two finishes at major events. Outside of Woods, only Greg Norman (10) and Ernie Els (10) are within eight of Mickelson over the past 50 years. Similarly, nobody who debuted outside of Woods in the past 50 years is even close to Mickelson’s 25 top-three finishes. Only Els (15) is within 10 of Mickelson. The same goes for top-five and top-10 finishes. Outside of Woods, only Els (23), Norman (20), and Nick Faldo (19) are within 10 of Mickelson’s 29 top-5 finishes, and only Els (35), McIIroy (31), and Norman (30) are within 10 of Mickelson’s 40 top-10 finishes. 

Ernie Els, Greg Norman, Nick Faldo, Brooks Koepka, and Rory McIIroy are the most accomplished golfers to debut in the last 50 years outside of Woods and Mickelson. However, the resume comparisons between those four and Mickelson end in a blowout in favor of Mickelson. With Woods and Nicklaus in a different dimension, Mickelson’s relative dominance over the most competitive 50-year stretch of golf that the PGA Tour has ever seen makes him a worthy selection for the 3rd spot on the all-time list. The argument for someone in the Hogan, Snead, Nelson triumvirate could’ve been strengthened had eight* major championships not been canceled during WWII. However, without knowing who would’ve won those tournaments, there’s no way to prorate resumes.

* There were actually 14 majors that were canceled, but the best American golfers like Hogan, Snead, and Nelson typically did not compete in the Open Championship (The British Open) during this era. Therefore it is unlikely that their resumes were negatively impacted by the six Open Championships that were not held.
