The Right-Handed Lefty: 5 Shocking Facts About Phil Mickelson's Golf Swing

The question of whether Phil Mickelson is truly left-handed is one of the most enduring mysteries in professional golf, and the answer is a fascinating contradiction that defines his entire career. As of late 2025, the six-time Major champion, universally known by his nickname "Lefty," remains one of the most recognizable figures in the sport, but the truth is he is naturally right-handed for almost every task outside of the golf course.

This unique biological and athletic paradox—a right-handed person who swings a golf club from the left side—is not a mere quirk; it is the foundational story behind his legendary, aggressive, and often unpredictable style of play. The reason for this anomaly traces back to his childhood and a simple, yet profound, act of imitation that set the stage for one of golf's most decorated careers on both the PGA Tour and the LIV Golf League.

The Mirror-Image Origin: Why a Righty Swings Lefty

The story of how Phil Mickelson became a left-handed golfer is a classic tale of childhood imitation and the power of repetition. It is the single most important factor in answering the question, "Is Phil Mickelson left handed?"

The Father-Son Practice Sessions

Mickelson's father, also named Phil Mickelson, was a right-handed golfer. When young Phil began to show interest in the sport as a toddler, he would stand opposite his father in the garage and mirror his swing. Instead of standing next to his dad and trying to replicate the motion on the same side, he faced him, treating his father's right-handed swing as a mirror image.

Because he was mirroring a right-handed swing, the natural action for the young boy was to swing from the left side. This foundational learning method ingrained a left-handed swing pattern long before he ever picked up a proper set of left-handed golf clubs. The process was entirely organic and unforced.

The Dominant Hand Theory

Many golf instructors and sports psychologists argue that this "wrong-sided" approach may actually provide a hidden advantage. In a conventional right-handed swing, the left arm is the lead or controlling arm, while the right hand provides power and feel. For a naturally right-handed person like Mickelson, the left-handed swing places his dominant, stronger right hand lower on the club as the "trailing" hand, which is responsible for power, clubface control, and feel.

This setup means his naturally stronger hand is the one guiding the clubface through impact, potentially offering superior control and power generation. This unique swing dynamic is often cited as a reason for his incredible short game touch and his legendary, high-risk flop shots. The strength and dexterity of his dominant right hand, applied to a left-handed swing, may be the secret ingredient to his success.

The 'Lefty' Advantage: Separating Myth from Reality

The presence of a dominant left-handed golfer like Mickelson naturally leads to discussions about whether lefties have an inherent advantage in golf. While the majority of courses are designed with right-handed players in mind, Mickelson has expertly leveraged his unique perspective.

Handling the Course Layout

Most golf courses, including Major venues like Augusta National Golf Club (home of The Masters), are structured to challenge the right-to-left shot shape (a draw) for right-handed players. For a left-handed player, the opposite is true: the left-to-right shot shape (a fade) becomes the natural challenge. However, Mickelson's ability to hit an aggressive draw—a right-to-left ball flight for a lefty—has often allowed him to attack pins and navigate doglegs that challenge his right-handed peers.

His dominance at the Masters, where he has won three Green Jackets, is often attributed to his ability to shape the ball around the course's challenging layouts, particularly the par-5s, which he has historically decimated.

The Mental Edge and Entity Status

Being one of the few elite left-handed golfers—a major entity in a right-handed sport—also provided a mental edge. Opponents were less accustomed to playing alongside a "Lefty," and his presence on the leaderboard was always a statistical anomaly. Mickelson, alongside other left-handed PGA Tour winners like Mike Weir and Bubba Watson, helped cement the "Lefty" entity as a distinct and powerful force in professional golf.

His longevity and continued competitiveness are a testament to the durability of his swing mechanics. In 2021, his stunning victory at the PGA Championship made him the oldest major champion in history at the age of 50, showcasing that the "right-handed lefty" swing is not just a novelty, but a masterclass in athletic adaptation.

Mickelson's Career Evolution and Current Status (LIV Golf)

Mickelson's professional journey has seen a dramatic shift in recent years, which provides the most current context to his career as of late 2025.

The Transition to LIV Golf

After a storied career on the PGA Tour, which included 45 wins and over $100 million in career earnings, Mickelson made a highly publicized move to the Saudi-backed LIV Golf League. This transition, reportedly involving a massive contract figure, solidified his status as one of the highest-earning golfers in the world, with his total career earnings surpassing $800 million from prize money and endorsements (such as Callaway and KPMG historically).

He currently serves as a team captain in the LIV Golf format, continuing to compete at the highest level while embracing a new chapter in his career. His presence in the LIV Golf League ensures that the "Lefty" phenomenon remains a headline topic in the global golf landscape.
