David Miller scored a quick-fire century but his efforts went in vain as South Africa fell 16 runs short of the 238 run target. Quinton De Kock scored a half century but looked completely out of form, struggling to get going throughout his innings.
India posted a massive 237 for three against South Africa in the second T20I at the Barsapara cricket stadium in Guwahati on Sunday.
K. L. Rahul (57) and Rohit Sharma (43) put on a 96-run opening stand to set the foundation.
Suryakumar Yadav (61) then took centre stage as he smashed five boundaries and as many sixes en route to his 102-run stand off just 40 balls with Virat Kohli (49 not out).
Dinesh Karthik then made some lusty blows in his seven-ball 17 not out.
Keshav Maharaj (2/23) was the most successful bowler for South Africa but it turned out to be a disastrous day for the rest of his bowling colleagues.
