South Africa are sweating on the fitness of powerful middle-order batter Heinrich Klaasen for their Champions Trophy Group B fixture against Australia on Tuesday as captain Temba Bavuma vowed not to take their injury-hit opponents lightly.

*South Africa hold a narrow advantage over Australia in overall head-to-head records in ODIs, winning 55 matches against Australia's 51. Three encounters between the sides ended in a tie and one meeting produced no result. *The Proteas have also won four out of the five ODIs against Australia.

Both teams made 300-plus totals in their opening games, so expect another run-fest on a flat surface in Rawalpindi

Ahead of the ICC Champions Trophy clash against Australia, South Africa skipper Temba Bavuma said that the fitness of wicketkeeper-batter Heinrich Klaasen is yet to be assessed and he is also taking part in the practice session.
