India strolled to a crushing seven-wicket victory over South Africa at Arun Jaitley Stadium to seal a 2-1 ODI series win after the Proteas were bowled out for just 99 on Tuesday.

It was only the fourth time in ODI history South Africa have been skittled for fewer than 100 runs, and the first time it has happened to them against India.

The hosts' spinners took centre-stage in Delhi, with Washington Sundar, Shahbaz Ahmed and Kuldeep Yadav tearing through South Africa in brutal fashion.

India then made light work of their chase, reaching 105-3 to wrap up a commendable series win.

South Africa never managed to find much momentum. Quinton de Kock (six) was quickly dismissed by Sundar (2-15), and although Janneman Malan (15) held out a little longer, Mohammed Siraj (2-17) soon toppled him.

Heinrich Klaasen (34) offered some resistance, but South Africa were already heading for a hiding when he was removed by Ahmed (2-32), as Aiden Markram, Reeza Hendricks, David Miller and Andile Phehlukwayo all failed to reach double digits.

The latter fell to Yadav, who took four of South Africa's last five wickets to post figures of 4-18, with India heading into bat with great confidence.

A miraculous turnaround never looked likely, with Shubman Gill (49) looking sharp before unfortunately getting halted leg before his half-century by Lungi Ngidi.

Nevertheless, Shreyas Iyer (28) got India over the line with 185 balls remaining, finishing with a flourish as he hit Marco Jansen (0-43) for six.

Just keep spinning

The pitch was considered an inviting one for seamers, but it proved to be India's spinners who did the damage.

Siraj, Sundar and Yadav took eight between them, though the latter was undoubtedly the standout as he ripped through South Africa with little fuss, taking four wickets in total.

Unsurprisingly, he was named Player of the Match.

Gill unfortunate

It would have been a deserved 50 for Gill if he had just hung on a little longer. Ultimately dismissed for 49, his total included eight fours as he generally fended off the South Africa attack impressively.

It would have been easy for India to go into bat with a bit of complacency given South Africa's dire total, but there was no sign of that from Gill.
