Fault: Inconsistent results when your ball is nestled by the collar, just off the green.
Fix: Modern courses – inland, largely – have a mown collar around the green which is bordered by rough.
If you run through the putting surface, the ball can often nestle against this rough barrier, making it tricky to putt and hard to hit the bottom of the ball with a wedge.
This is where the 'belly wedge' comes in.
It'sa shot you often see on tour, where the rough bordering the collar is long and grabby.
Use the leading edge of a wedge, where all the weight is, and just make a passive, pendulum stroke at the ball.
There's no 'hit'. It will come out with a lot of topspin – so go and practise it.
