At the Wanderers Another Pink Day, another thrilling hundred. Aiden Markram provided unequivocal evidence that he's in the form of his life with a magnificent and big maiden century in the ODI format as the Proteas upheld their end of the bargain for automatic World Cup qualification, beating the Netherlands by 146 runs in the third and final encounter between the two sides here on Sunday.The two victories this weekend put them on 98 log points and eighth in the ICC Super League table, leaving the onus on Ireland to whitewash Bangladesh 3-0 in May as well as do so with a big spike in their net run rate.On a day where the annual charity event didn’t quite deliver the sell-out crowds of previous years, predominantly because of some suspect high ticket prices, Markram delighted with a majestic innings.The classy right-hander smashed a limited Dutch attack to all parts on his way to a 126-ball 175, a knock that ensured the Proteas' high-scoring tradition in Pink ODIs would be kept up. AS IT HAPPENED | Proteas v Netherlands Markram ridiculed a slow surface, looking in control from the outset and driving beautifully, vitally ensuring that South Africa didn't panic after making a sluggish start.Both Temba Bavuma (6) and Quinton de Kock (6) were out to poor shots off the bespectacled, enthusiastic Vivian Kingsma (2/80), while Rassie van der Dussen (25) also wasted a decent opportunity when he found fine leg off an Aryan Dutt long-hop.When Heinrich Klaasen, racing to 28 off 21, also went through his pull shot too early, there were legimitate reservations about the Proteas' ability to combine a healthy rate with a defining partnership.But Markram found a commanding David Miller as partner as the duo added 199 of just 118 balls
