Sports help?

Question

ok i am a very good golfer when im out playing for fun but when i get into tournaments and am playing with other kids i get really bad and end up losing

can someone help me figure out how to stop this from happening?

Answer 1

its a mental thing/ relax/meditate/focus/

Answer 2

Because you are thinking so much of winning??  Do not focus on the score.... focus on your swing and the target.
