Kevin Pietersen crashed boundaries off his first two balls but hit an Albie Morkel full tossdown to Roelof van der Merwe at mid-on, and the fielder dived to his left to take a stunning catch.
Having drilled a full tossdown the ground for his 13th four - he also struck three sixes - Pietersen walked past a short, wide delivery from leg-spinner Akito Willett under instruction from the dressing room.
