Johannesburg - Proteas batsman David Miller says he has embraced the responsibility and challenge that comes with representing South Africa ahead of the ICC World Twenty20 in Bangladesh.

Miller will make his maiden appearance for the Proteas at a World Cup - having made his international debut against the West Indies in 2010 - when South Africa takes on Sri Lanka in Chittagong on Saturday.

“There is always some sort of pressure that comes with playing international cricket,” Miller said in a Cricket SA (CSA) press release on Monday.

“For me personally, I've tried to play as much cricket as I can in the off-season overseas and locally in South Africa.

“The more cricket you play the more experience you get and the better the decisions you make on the field become.

“I enjoy that sort of pressure and I try to relish the moments that come about.”

The 24-year-old said he thrived on his role as the bludgeoning finisher with the bat, and has learnt to cope with the expectation that comes his way on every occasion he steps to the crease.

“It's another opportunity for me to do well,” he said.

“It's my first World Cup so it's a dream come true for me and a really special moment.

“To have the opportunity to go out and play cricket in this tournament is great. The expectation is there but I'm going to go out and give my best in every situation, that's all I can do.”

Miller said the Proteas would have to “be at their best” to win the tournament.

The Proteas' first assignment is a warm-up match against Bangladesh A on Tuesday.

The squad held their first training session of the tournament at the Dhaka Academy on Monday.

“The two warm-up games are going to be really good for us in terms of adapting to the conditions and the heat,” Miller said.

“We will also have a few nets in between so the preparation leading up to our opening match is going to be vital.”
