There are many different ways to play shots around the green out of the rough. Variables include the lie, type of grass, pin position, and even firmness of the green. One option is to play a splash shot similar to a bunker shot. Having grown up playing out of Bermuda grass rough, I find this to often be an effective technique. Simply use the same style of shot as if playing out of a bunker. Make sure to staff firm with your wrists, but let the leading edge cut through some of the grass. The loft and bounce of the sand wedge will do a lot of the work. See the video link to my sand shot techniques and apply the same principles.
