Aiden Markram was left a disappointed captain after South Africa were condemned to yet another defeat in the one day internationals. India demolished South Africa in the six-match series with their 8-wicket victory in the sixth and final ODI at the SuperSport Park in Centurion on Friday.South Africa had a brilliant run in the ODIs winning 17 matches on the trot at home but they were outplayed completely by India.With the win in the final ODI, India thumped South Africa 5-1 in the series, equalling the biggest thrashing South Africa has ever received in an ODI bilateral series involving over five games. The only other team to beat South Africa 5-1 was Ricky Ponting’s Australia in 2001/02.Markram was handed the ODI captaincy in only his third match in the format after regular skipper Faf du Plessis was ruled out of the series with a finger injury.India strode to a comfortable win at Centurion as they reached their victory target with 107 balls to spare after putting South Africa into bat and bowling them out for 204.India, who have taken over from South Africa as the world’s top-ranked ODI team, were 206 for two wickets in reply in another dominant performance with captain Kohli again leading from the front.”Quite a tough series. Something we have to look back at. Try find the reasoning of why we haven’t been as good as we know we can be,” Markram said at the post match presentation ceremony.The young South African skipper was all praise for India and said the Proteas could learn a lesson from the visitors.advertisement”If you look at them, their players have cashed in. We can learn a lesson from them. It’s been tough no doubt. But we wouldn’t want it any other way. That’s how you learn as a young captain. If there’s a time to learn, now would be it,” he said.India and South Africa will next play a three-match Twenty20 International series from Sunday. Markram will once be at the helm to lead South Africa and he is hopeful of his team doing well in the T20s.”Back to the drawing board now. Hopefully the team which is playing the T20Is can do the country proud,” Markram said.
