South Africa's bowling coach Charl Langeveldt is convinced that the Proteas have made progress with their death bowling despite losing to Australia at the Wanderers on Sunday.
The home team failed to defend a total in excess of 200 as the Aussies won by five wickets to level the series at one-all going into the deciding game at Newlands on Wednesday.
Kagiso Rabada is showing plenty of promise as the 20-year-old nailed a few yorkers on Sunday with the Proteas not just relying on Dale Steyn to bowl at the death.
Ahead of the World T20 in India, Langeveldt wants the bowlers to have as many options as possible when bowling at the end and not become predictable.
Langeveldt said: "Our skill levels have improved, and that was our main focus in the last year-and-a-half. Everyone can bowl at the death and you don't become predictable.
"We try and encourage the guys to think out of the box sometimes. Maybe bowl a wide yorker or a wide slower ball. You don't want to go into the hitting zones in India, where the straight boundaries are a lot shorter."
However the former Proteas swing bowler says they have to defend big totals like the one they had in Johannesburg if they want to be successful at the global event.
Langeveldt continued: "If you want to win a World Cup you need to able to defend 200. We didn't pull it through, we had a lot of ifs and buts.
"We need to win games like that. If you want to become a champion team you need to adapt – T20 is all about adapting."
