David Miller (South Africa)
The 33-year-old has taken a while to realise the whole prospect of his power game, but he has been South Africa's beaut player over the last 12 months. The southpaw seems to have taken his game to the next level, which was first apparent in the Indian Premier League (IPL) earlier this year. He enjoyed his best-ever season, scoring 481 runs at an average of 68.71 for eventual champion Gujarat Titans (GT).
He has carried that shape into international cricket, and in the recent series in India, he created an unforgettable 106-run knock off 47 balls, albeit in a losing cause. If he continues to finish games as he has of late, he will go a long way in South Africa's bid for its maiden international title.
