South Africa's T20 World Cup squad has excluded promising young players Ryan Rickelton and Tristan Stubbs, a decision defended by selection convenor who cited the need for 'big calls'. Both players, despite IPL experience, were not selected for the upcoming tournament in India and Sri Lanka. Aiden Markram will captain the squad, which includes veteran Quinton de Kock as the sole wicketkeeper-batter and pacer Anrich Nortje. Rickelton and Stubbs' recent T20I performances were noted as factors in their exclusion.
