How to Caddy for a Professional Golfer

By Spencer Lanoue
November 2, 2025

Becoming a professional caddy is a demanding yet rewarding role that goes far beyond simply carrying a golf bag and raking bunkers. Looping for a tour pro makes you a strategist, a psychologist, a logistician, and a trusted partner on the course. This guide will walk you through the essential skills, daily responsibilities, and mindset required to caddy at the highest level of golf, breaking down exactly what it takes to succeed on the bag.

It's More Than Just Showing Up and Keeping Up

The old caddy mantra used to be, "Show up, keep up, and shut up." While that holds some truth, the modern tour caddy is an active and influential teammate. Your player is the skilled artist, but you are the architect providing the blueprint. They are trusting you with their livelihood, and your preparation, judgment, and demeanor directly impact their performance. You’re not just carrying a bag, you are managing a one-person business where the product is a score, and your job is to remove every possible obstacle and clear the path for your player to execute.

Pre-Tournament Preparation: The Work Before the Work

The best caddies win tournaments for their players on Mondays and Tuesdays, long before the first shot is hit on Thursday. Exceptional preparation is what separates a bag carrier from a professional looper.

Mastering the Golf Course

Your first job upon arrival is to become an absolute expert on the golf course. A standard yardage book isn’t enough. You need to walk the course - ideally without your player - and create your own notes. Your goal is to chart details no one else sees.

  • Walk Every Hole: Pace off exact distances from every sprinkler head to the front edge of the green. Note the distance and carry number over every bunker, water hazard, and penalty area from primary teeing grounds.
  • Map the Greens: Meticulously chart the slopes and breaks on every green. Find the general fall lines (the direction everything drains) and note subtle humps and collection areas. Identify where not to be. A note like "DO NOT BE LONG RIGHT OF THIS PIN" is worth its weight in gold. Look for old cup locations to understand how different putts will break.
  • Identify Strategic Spots: On par 4s and 5s, find the ideal layup spots. What’s the widest part of the fairway? Where is the flattest lie? What angles provide the best view into the green? This information allows you to construct a clear course strategy.

Knowing Your Player Inside and Out

Your second responsibility is to know the person whose bag is on your shoulder better than anyone. This relationship is built on trust and communication over hundreds of hours.

  • Know Their Numbers: You must have their carry distances for every club memorized. Not just a perfect-lie, no-wind number, but their "stock" yardage when they hit it 85-90%. You also need to know their flight windows - how high do they hit their 7-iron versus their 5-iron? This affects club choices in the wind. Understanding elements like how to choose golf club shaft stiffness is part of this deep knowledge.
  • Understand Their Tendencies: What is their go-to shot shape when they need to find a fairway? Does their miss tend to be left or right when they feel pressure? What is their emotional baseline? Some players need a stream of positive reinforcement, while others want a simple, quiet confirmation of the plan. Knowing how to manage their energy is a game-changer.
  • Respect Their Routine: The pre-shot routine is sacred. Your role is to help them get into it and protect them during it. Know when to give information and when your job is done. The final moments before the swing belong to them and them alone.

The Weather Factor

Predicting how weather will influence a golf ball is part art, part science. You need to be the resident meteorologist for your team.

  • Track Wind Patterns: Check the forecast consistently. Notice the prevailing wind direction and how it impacts "crosswind" holes that might feel they are playing into a headwind due to the treeline. Learn how much a 10 mph wind affects your player's ball flight. This must be a number you both agree on (e.g., "This wind is about a one-club hurt").
  • Adjust for Conditions: Is the course playing soft or firm? Soft greens mean you can attack pins with precision. Firm greens mean you need to calculate a 'playing yardage' that accounts for bounce and release. Heavy, humid air will make the ball fly shorter than dry, thin air at altitude. You are responsible for all of these small calculations.

On the Course: In-Round Execution

This is where your prep-work pays off. Your presence should bring clarity and confidence, not confusion. Your job is to make every decision as simple as possible.

The Yardage: More Than Just a Number

Providing a yardage is a detailed process. When the player asks, "What have you got?" you don’t just give them a number from a laser. You deliver the full picture.

An ideal yardage exchange might sound like this:

“We've got 152 yards to the pin. It’s 144 to carry the front edge and 165 to get to the back. There's a slight help from the left. Factor in the downhill lie, and for me, it’s playing a solid 148. The big miss is long, short is fine all day.”

You’ve provided multiple data points and a clear strategic recommendation. You've confirmed the plan and reinforced the play, allowing them to swing with conviction.

Club Selection: The Conversation

You suggest, but the player decides. Your job is to provide all the variables - the "playing number," the wind, the lie, the shot shape they see. Sometimes a player will have a feel for a certain shot, like a knocked-down 7-iron when the yardage says full 8-iron. Your role is not to argue but to confirm their feeling or present a clear reason why your play might be better ("If you don't catch that knockdown perfectly, you'll be in the front bunker."). It’s a dialogue built on mutual respect.

Reading Greens: The Confirmation

On the green, you are the second set of qualified eyes. Use the detailed charts you developed in practice. When your player walks you through how they see a putt, your job is to either confirm their read or offer a different viewpoint.

  • Say what you see: "I see a full cup of break outside right, too." This validation can give a player immense confidence.
  • Offer polite alternatives: If you disagree, state it simply. "I know you're seeing it left-edge, but from back here, it looks much straighter to me coming up the hill." This gives them another perspective without undermining them.

You are an advisor. You provide your expert reading, a recommendation, and then you step away and let them own the final decision.

Mental and Emotional Management

This is perhaps your most important role. A golf round is an emotional rollercoaster, and you're the steadying force. Great caddies know how to speak and when to be silent. After a bad shot, your reaction matters. A calm demeanor, taking the club, cleaning it, and speaking only about the next shot keeps your player grounded in the present. If they make three birdies in a row, your job is to keep them from getting ahead of themselves, gently refocusing them on the next tee shot. You control the emotional thermostat.

Post-Round Responsibilities

After the scorecard is signed, your work continues.

  • Debrief the Round: Have a short, productive conversation about the day. What did we do well? What decisions cost us a shot? This isn't about placing blame, it's about learning and refining the game plan for the next day.
  • Maintain the Gear: The golf bag is your office. Thoroughly clean every club, especially the grooves. Check your player's spikes for wear. Restock the bag with balls, tees, gloves, and snacks for tomorrow.
  • Look Ahead: Get the pin sheet for the next round. See how it changes your strategy for certain holes. Check the updated weather forecast and start thinking about the conditions for the morning. Preparation never stops. How to organize golf clubs efficiently in the bag is also key for smooth play.
