Play the course and not chase a score. Manage your shots on the course and do not play shots you are not comfortable with. Enjoy the rounds instead of chasing a trophy. I assume you are referring to playing in competitive events. We all have bad rounds in tournaments.

How much higher are your scores than your typical rounds? Are the additional strokes coming from one particular area of your game (e.g., driver, bunker, chipping, etc.) that isn’t challenged by your home course? It may be as much the mental side — setting expectations too high, hanging on too poor shots for too long, not giving yourself grace, etc.

I have the same problem. I get the jitters too often when playing in a tournament. Even when playing with my crew, someone always shouts out a dollar a hole, and I can 3 putt from 2 feet.

It's easy, you don't have full control of your emotions when a score is on the line. That is another skill all together. That emotional control bleeds over to your golf swing when the pressure is on. Your swing gets short, quick, and it's easy to get out of sync.

***Golf is an emotional game. To compete, you have to learn to breathe, be patient and pick your spots. As an example, I'm a scratch golfer, pretty confident in my ability. In tournament play, I'm a legit 3-4 handicap.

I used to get the jitters bad too.

Now I just ask myself if I would rather be working or golfing...that usually helps

Play the next shot, forget the last. All you can do is play the course and yourself. That is your only competition. Try to stay in the moment and focus only on what you can control.
