Miller slammed 106* off 47 balls but India took an unassailable 2-0 lead in the series.
Invited to bat first, the hosts piled up a massive 237/3 in their 20 overs on the back of half-centuries from Suryakumar Yadav (61 off 22 balls) and KL Rahul (57 off 28 balls). Virat Kohli (49* off 28 balls) and captain Rohit Sharma (43 off 37 balls) also made notable contributions with the bat.
Amid the carnage, left-arm spinner Keshav Maharaj returned with impressive bowling figures of 2 for 23 in his four overs.
In reply, the Proteas were struggling at 47/3 after 6.2 overs and it seemed that they will struggle to get near the target.
However, David Miller produced one of the best counter attacks in the shortest format to leave everyone in awe. The southpaw wreaked havoc on the Indian bowlers and notched up his second T20I century in just 46 balls.
Miller eventually returned with 106 not out off 47 balls but his whirlwind knock went in vain as South Africa fell 16 runs short of the target. In the process, he was involved in an unbeaten 174-run partnership with Quinton de Kock, who finished with 69 not out off 48 balls.
While the Indian bowlers were taken to the cleaners, seamer Deepak Chahar returned with economical figures of 0-24 in his four overs.
After the game, David Miller was congratulated by Rohit Sharma and Virat Kohli for his valiant ton.
Cricket fraternity also lauded the South African left-hander as he almost pulled off a heist for South Africa while chasing a mammoth target.
