Once he was done telling the press how his team had gone about completing a 5-0 thrashing of Australia in their one-day series at Newlands, captain Faf du Plessis took a seat at the side of the room. He plopped an ankle over a knee, folded his arms across his chest, allowed his face to melt into a wide smile, cast a sideways glance to the top table and handed over to Rilee Rossouw - who was not supposed to play and ended up as South Africa's leading run scorer.Rossouw drilled 122 on Wednesday to help South Africa win by 31 runs and achieve the first 5-0 whitewash of the Australians by any opponent .Was he relieved that, having made five ducks in his first 10 ODIs, he had finally proved he could play at the highest level?"I didn't think that, but thank you for making me feel relieved," Rossouw said."I am just happy I got given a good run."Rossouw knows all about frailty, having had to overcome a stress fracture of the foot and a dislocated shoulder since September.He was, in fact, playing through the pain on Wednesday.How, he was asked at Newlands, was his finger in the wake of a blow he took while fielding in the fourth match of the series at St George's Park on Sunday?"My finger is fractured in a couple of places. But it's not the first time I've played with a fractured finger. I had a couple of (anti-inflammatory tablets) but everything went smoothly."It didn't really affect me while I was batting but there was a bit of pain," he said.Another hero from Newlands, Imran Tahir, has been served with two demerit points and fined 30% of his match fee after he engaged in a verbal exchange with Australian David Warner. - TMG Digital..
