The wicket-keeper in the sport of cricket is the player on the fielding side who stands behind the wicket or stumps being watchful of the batsman and ready to take a catch, stump the batsman out and run out a batsman when occasion arises. The wicket-keeper is the only member of the fielding side permitted to wear gloves and external leg guards.[1] The role of the keeper is governed by Law 27 of the Laws of Cricket.[1]
