So many people I play with insist on hitting wedge shots when they are only a few yards from the green. If it's really wet in front of the green then maybe you will have to, but if it's dry use a club with just enough loft to get the ball a couple of yards onto the green and let it roll to the hole. For me I use a variety of lofts depending on how far from the edge of the green I am.

30+ yards - sand wedge

20-30 yards - pitching wedge

10-20 yards - 9 iron

5-10 yards - 8 iron

3-5 yards - 7 iron

1-3 yards - 5 iron

0-1 yards - putter

Of course if you're in rough then this doesn't apply. Then you have to use a wedge.
