Time running out for South Africa batsmen as World Cup approaches

After years sharpening his talents in various cricketing hinterlands, Rassie van der Dussen has arrived fully formed - and just in the nick of time for the World Cup - in international cricket, and he is averaging 91.66 after seven ODIs. That number must surely come down eventually, but van der Dussen has given himself the best possible start.Quinton de Kock has also enjoyed a renaissance over the last few months, and like du Plessis, he has a shot at leveling up to achieve greatness. This season, de Kock has averaged 59.12 in Tests and 43.87 in ODIs, and across formats his run of international scores since South Africa got back from Australia reads: 94, 81, 86, 1, 80, 55, 83, 0, 33, 18, 129, 59, 45.If there's anything to quibble about in those numbers, it's that de Kock has not converted as many of his innings into hundreds as he possibly might have - something he readily admits."Lately I haven't been converting these 80s and 90s into the bigger scores that I've wanted to, so I am quite disappointed," de Kock said after he fell six runs short of what would have been a 14th ODI ton on Wednesday.
