Cape Town – Hashim Amla is set to captain the Proteas in the Twenty20 and One Day International matches against Australia.Speaking to Die Burger, Gary Kirsten confirmed that the Proteas vice-captain would be elevated to skipper in the absence of the injured AB de Villiers, who has been ruled out for 4 to 6 weeks after undergoing surgery on his left hand.Kirsten acknowledged that the loss of De Villiers was a blow, but insisted his absence would not disrupt the team.“This is a great loss to the Proteas,” said Kirsten."It's always difficult when you lose a world class player like AB.”"I feel sorry for him. He was so excited about his chance to be captain, "Kirsten said.Hashim Amla’s appointment pours cold water over speculation of a recall to the leadership role for Johan Botha, whose captaincy has been lauded after admirable performances in both the IPL and the Champions League. The Australians arrive in South Africa in high spirits after coming off Test and ODI victories against Sri Lanka.Kirsten felt that although the Proteas would have little time together as a group before facing the Australian challenge, he was encouraged by some strong performances from his players in other competitions."The guys will only have a few days together before the first game, but it's good that they are showing some good form (in the Champions League and Supersport Series)."The first game between South Africa and Australia is a Twenty20 match scheduled for Thursday the 13th of October.
