South Africa defeated India in Dharamsala and Cuttack to clinch the Twenty20 series 2-0 after the third and final match was abandoned owing to a wet outfield.
"As a team, we definitely expect them to put in a big performance in the two series. We are under no illusion that it is going to be a walkover in the ODI series. We know that we have to fight hard and play well and take it one game at a time," Duminy, who was adjudged man of the series, told a news conference after yesterday's washout.
"Our focus is on Kanpur and hopefully we can start off well in that series as well. That is going to give us a lot of confidence. We know that they are a great ODI team so it is important for us to start off well in the ODI series," Duminy said.
India had set up a mammoth 200 target in Dharamsala riding on Rohit Sharma's maiden century but his effort was overshadowed by the Duminy's unbeaten 68 that fashioned a thrilling seven-wicket for the visitors.
Terming the Dharamsala win as a turning point, Duminy said, "It was a big one for us especially chasing 200 gave us a lot of confidence going into the second T20I. That is going to be a big tick for us in the T20 format. With the results that we have got here now, they will give us a lot of confidence going into the T20 series against England and Australia and obviously the World cup coming in a few months."
