Paul Collingwood's one handed stunner at square leg to send back Devon Smith in the England-West Indies match today was, in my opinion, the best catch of the world cup.
Smith shaped for a drive (1) and end up slicing the ball (2). Collingwood took off, twisted himself to position his dominant hand near the ball (3) and took an airborne catch (4). Somehow he held on to it (5) while he was in the air (6) then on the ground while rolling (7). He was mobbed by his teammates who knew he had done something special (8).
