Shreyas Iyer hit a magnificent century as India trounced South Africa by seven wickets in Ranchi to level the ODI series.
South Africa had won the first match by nine runs in Lucknow, after a 2-1 reverse in the preceding T20I series, but India made light work of their chase in Sunday's second tussle between the teams.
Iyer hit 15 fours in his ODI career-best 113 not out, with Ishan Kishan weighing in with 93 as the third-wicket pair put India firmly on course for victory.
A stand of 129 for the third wicket between Reeza Hendricks (74) and Aiden Markram (79) underpinned South Africa's 278-7, with Heinrich Klaasen (30) and David Miller (35no) also making handy contributions lower down the order.
Opening bowler Mohammed Siraj took 3-38 from his 10 overs, including the wickets of Hendricks and opener Quinton de Kock. The paceman bowled the final over of the innings, from which South Africa could only prise three runs, putting the hosts on a high heading into their reply.
India lost openers Shikhar Dhawan, who captained the side, and Shubman Gill before the score reached 50. However, Kishan and Iyer soon took a grip on proceedings, putting on 161 for the third wicket.
Kishan had clubbed seven sixes and went down on the attack, caught by Hendricks while attempting to pull away a delivery from Bjorn Fortuin.
Sanju Samson joined forces with Iyer, making 29 not out in the supporting role before Iyer chopped away the winning boundary, taking India to a winning score of 282-3 with 4.1 overs to spare.
Get set for Delhi decider
This three-match series will come to a head on Tuesday, before the teams head off to the T20 World Cup. India go there on a high after the batting exploits of Iyer and Kishan.
Kishan might be kicking himself at missing out on a century, with his previous highest score in ODIs having been a modest 59.
Iyer had one previous ODI century, a 103 that he scored against New Zealand in Hamilton in February 2020. In his last six ODIs, he now has one century, four 50-plus scores, and a 44.
Super Siraj
'Death' bowling can be a thankless task, but Siraj showed himself to be a classy finisher as the Proteas were left frustrated. His innings haul gave him his best bowling figures in ODIs, beaten only by his 3-29 against West Indies at Ahmedabad in February of this year.
