Today i played in a competition and got through to the second round that is to be played tomorrow but i am having trouble with thinning the ball.

I am not exactly thinning it as it does not go really low but i am definitly catching the ball on the bottom of the clubface, it feels as though i am hitting the ball with the leading edge of the club. This is happening with all the clubs and it is particulary annoying with the driver because i am losing so much distance, i was hitting it about 20-30 yrds shorter with the driver than i normally do.

I would be grateful for any advise as i need this sorted out for tomorrow.

Thank you
