Play great in practice but awful in tournaments - help?

[TristanBlevins]

Whenever I'm playing by myself or with a few friends I always play really well - usually shoot low-mid 70s, I've even shot in the high 60s a few times. But, whenever I play in a tournament I always play AWFUL - I've only broken 80 3 times in about 20 tournaments this year. I actually shot +1 on 11 holes yesterday and then went and shot 86 on 18 today. I know there's nothing wrong with my swing, it's all mental, but does anybody have any tips to help? Much appreciated.

Try to play more non-tournament rounds similar to how you will play in a tournament- i.e. hole all putts, play the ball down, no mulligans, etc.

Try figuring out what you do differently on tournament days compared to when you are more relaxed with your friends.  Consider having some wagers with your friends to try to simulate tournament pressure.

I usually do play the ball down and don't use any mulligans (If I do I usually just use 1 or 2), but sometimes when I'm playing with friends we'll give each other putts, like match play.

We never really do wagers (as I typically play with guys who are better than me) but we will say "Okay, this is for the *insert major here*" and play exactly like we would in a PGA tournament, in which case I usually hang with these guys up until the last 5 or 6 holes when I typically have an inconvenient bogey or something and sort of fall apart.
