The Straight Answer: What Golf Ball is in Phil Mickelson's Bag?
Phil Mickelson plays the Callaway Chrome Soft X LS golf ball. This has been his ball of choice for the past few seasons, and it's a model he had a direct hand in developing with Callaway's R&D team. He doesn't just play this ball, he helped create it to fit the very specific needs of his legendary game.
You’ll typically see him using a version with Callaway's Triple Track Technology - the three red and blue lines that serve as a powerful alignment aid on the green. For a player who relies so much on confidence and feel, having that visual reassurance over every putt is a significant advantage. This choice is not an accident, every part of this ball is engineered to complement a player with tremendous speed and a masterful touch.

"LS" stands for Low Spin, and that two-letter designation is the entire story of this golf ball. While most premium golf balls try to balance speed, feel, and spin, the Chrome Soft X LS tilts the scales heavily towards one primary goal: reducing spin off the driver and long irons for players with very high swing speeds. Let’s break down its components to understand how it works.
Construction and Technology
4-Piece Construction: Unlike the 3-piece balls often favored by mid-handicappers, this 4-piece construction allows engineers to create more separation between the core and the cover. This multi-layer design means each layer can be optimized for a different purpose - the inner layers for rocket-like speed, and the outer layers for feel and control. For more on how different types of balls are constructed, read about the different types of golf balls.
Hyper Elastic SoftFast Core: This is the engine of the golf ball. It's designed to create insanely high ball speeds, especially when compressed by a driver at high speed. It's large and resilient, acting like a slingshot to transfer as much energy as possible from the clubface to the ball.
"Low Spin" Mantle System: The layers between the core and the cover are specifically designed to keep spin down on a full-swing shot. When you hit a driver, these layers work in concert with the core to produce a powerful, penetrating, and low-spinning ball flight that bores through the wind.
Thin Proprietary Urethane Cover: This is where the magic happens around the green. While the inner parts of the ball are built for low spin, the very thin, soft urethane cover is incredibly "grabby." On short shots with a wedge, the grooves of the club face can bite into this cover, generating massive amounts of spin for drop-and-stop control.
In simple terms, think of it as a dual-personality golf ball. Off the tee, it behaves like a low-spin distance rocket. Around the greens, it transforms into a high-spin, precision instrument.
Why Does This Ball Suit Phil's Game?
A golf ball is a piece of precision equipment, and a pro’s choice is never random. The Chrome Soft X LS is a perfect match for "Lefty" for a couple of very specific reasons that tie directly into his famous playing style.
1. Taming the "Bombs" with Low Spin
Phil has always been known for one thing above all else: speed. Even in his fifties, he possesses a clubhead speed that rivals players half his age. This incredible speed is his greatest asset, allowing him to hit "hellacious seeds," as he calls them. However, high speed can also be a liability. The faster you swing, the more spin you can generate. Too much backspin with a driver causes the ball to balloon up into the air, losing distance and making it vulnerable to the wind. It also exaggerates misses, turning a small fade into a big slice.
The Chrome Soft X LS is his solution. The low-spin characteristics of the ball effectively put a "governor" on his driver spin. It allows him to swing as hard as he wants, transforming all that speed into forward momentum instead of backspin. The result is a more penetrating, less lofty ball flight that maximizes his distance and, just as importantly, helps him find more fairways.
2. Fueling the Short-Game Wizardry
If Phil is a "bomber" off the tee, he's a surgeon around the greens. His legendary short game - those "Philops" and delicate spinning chips - depends on generating extreme amounts of spin. This is where the ball's second personality comes into play.
The thin urethane cover of the Chrome Soft X LS provides the bite he needs. When he opens the face of his wedge for a flop shot, he knows the ball will grab the grooves and come out with maximum spin, checking up quickly even on the fastest greens. This is the trade-off that premium balls like this offer: the ability to reduce spin on one end of the bag (driver) while maximizing it on the other (wedges). For a player whose scoring ability hinges on recovery and creativity around the greens, having absolute trust in spin generation is non-negotiable.

It's also worth remembering that Phil played a pivotal role in the very existence of the Callaway Chrome Soft family. When he first joined Callaway, tour players universally believed that a "soft" ball meant a "slow" ball. The conventional wisdom was that you needed a firm, high-compression ball (like the Pro V1x he used to play) to get tour-level distance.
Phil's feedback helped challenge that notion. He pushed Callaway's engineers to develop a ball that felt soft and had incredible spin around the greens but also had a fast core for distance. This exploration led to the original Chrome Soft, a ball that completely changed the landscape of the premium ball market.
The Chrome Soft X LS is the ultimate evolution of that concept, tailored for his specific needs in the modern game. It's not just a sponsorship, it's a piece of equipment that carries his design DNA.

This is the most important question for any amateur golfer. It's fun to use the same gear as the pros, but it's only a good idea if it actually fits your game. So, is the Callaway Chrome Soft X LS right for you?
Who It's For: The High-Speed Player
You might be a great candidate for this ball if you fit this profile:
You have a high swing speed. Generally, this means a driver clubhead speed of 105 mph or higher. If you swing slower than this, you will struggle to properly compress the core and will likely lose distance compared to a softer ball. Understanding your club speed in golf is crucial for ball selection.
You struggle with too much driver spin. Do your drives tend to climb too high and "stall" out in the air, especially into the wind? Do your misses tend to curve dramatically? If so, the low-spin design of the LS could help you produce a stronger, more accurate ball flight.
You want tour-level greenside spin. You need to be able to generate spin to truly benefit from the cover. If you can make solid, descending contact with your wedges, this ball will reward you with exceptional stopping power. Learning how to chip a golf ball with a wedge effectively is key here.
Who Should Probably Look Elsewhere: The Average Golfer
For the vast majority of amateur golfers - those with driver swing speeds under 100 mph - the Chrome Soft X LS is probably not the ideal choice. Here's why:
It will feel too firm. Without the speed to properly compress it, the ball can feel "clicky" or hard off the face, which can be uninspiring and hurt your feel on and around the greens.
It may launch too low. Most average golfers need help getting the ball in the air. A low-spin ball naturally wants to fly on a lower trajectory. This could cost you valuable carry distance, especially if you already have a low ball flight.
Great Alternatives in the Callaway Family
If you love the technology but aren't Phil Mickelson, Callaway has excellent alternatives:
Callaway Chrome Soft: This is the flagship model for a reason. It's the softest of the three and offers the most forgiveness. It's designed for golfers with moderate swing speeds (below 95 mph) who want a great all-around ball with exceptional feel.
Callaway Chrome Soft X: This is the middle ground. It's firmer than the standard Chrome Soft but softer than the LS. It's for players with higher swing speeds (95-105+ mph) who still want a bit more spin and a higher flight with the driver than the LS model provides. It offers a great blend of both distance and control.
Ultimately, the best way to determine the right ball for you is to test different models and see which one performs best with your swing and preferences. Consider reading more about how to choose a golf ball for your game.
Final Thoughts
Phil Mickelson plays the Callaway Chrome Soft X LS because it is precision-engineered to maximize his strengths - extraordinary clubhead speed - while providing the fine-tuned control he needs for his world-class short game. The most important lesson an amateur can take from Phil's choice is to find a ball that fits their own unique game, not just copying their favorite player.
