The Cape Cobras have their task cut out as they take on Trinidad and Tobago in a must-win encounter.
And Cobras wicket-keeper Dane Vilas believes his team is confident of seeing off the Caribbean side's spin attack on the difficult MA Chidambaram strip.
"Luckily, we are playing them at the end, so they're not a completely unknown entity," Vilas said at the pre-match media conference.
"We've done some work on them, they bowled brilliantly yesterday [against Chennai Super Kings]. I think the key to the game against Chennai was that they took the pace off (the ball) quite a lot. A lot of bowlers that we've faced have taken the pace off using different variations. So hopefully we've got that covered," he said
Asked to name one area the team needs to improve upon, he said, "It's basically a quarter-final for us, we have to win this game. We had a long pre-season. One key area we can improve on is probably our fielding. I think we have not been the fielding side we can be in this tournament "
Vilas said he is confident about the South African side's own spin attack, despite it going for runs in the rain-hit match against Mumbai Indians in Bangalore, when the latter amassed 176/6 in 20 overs.
"We're very confident. (The Chennai and Bangalore pitches) are completely different. The one in Chennai helped spin, while the Bangalore one was a lot flatter and a better pitch to bat on."
"But we've played three games here and JP (Duminy) bowled a brilliant spell against Chennai, taking four wickets against great players of spin and we've also got Robin Peterson," he said.
