Times of change: Fearless and free is key in Walter's new Proteas blueprint

In a spot of bother at 142/5 in chasing 261 for a series-levelling victory, Heinrich Klaasen (119* off 61) and Marco Jansen (43 off 33) combined for a thrilling, match-winning stand of 103 (62) that saw the Proteas obliterate the target.
