Dec 6 (Reuters) - India registered a 2-1 series victory against South Africa after opener Yashasvi Jaiswal's maiden hundred in one-day internationals secured their nine-wicket romp in the third and final match in Visakhapatnam on Saturday.

Jaiswal, who played second fiddle in an opening stand of 155 with Rohit Sharma (75), smashed an unbeaten 116 as India chased down a 271-run target with more than 10 overs to spare.
