Chasing 243 for victory, the hosts rode on opener Rohit Sharma’s 109-ball 125 to achieve their target in 42.5 overs at Nagpur and get back to the top of ODI world rankings table.
India, who reached the ODI summit after three straight wins in the series, had slipped behind South Africa following their loss in the fourth game. They were already the top Test team.
“It feels good. It was a really convincing series win for us. Ticked all boxes… We had a chance to retain the No. 1 spot and we ended up doing that,” Kohli said at the presentation.
It was a disciplined bowling effort led by spinner Axar Patel, who claimed three wickets, that set up India’s comfortable victory after restricting the visitors to 242-9.
In reply, Sharma and Ajinkya Rahane, who made 61, put on a 124-run opening stand to lay a solid foundation in another dominating performance in recent times.
“We repeated the way we played against Sri Lanka (beat them 9-0 across the three formats), proud of that. Shows the quality of the side, regardless of the opposition,” said Kohli.
Man of the match Sharma, who opened his account with two successive boundaries after 14 deliveries, was the first to get to his fifty with a double off Marcus Stoinis.
Rahane also got his fourth successive 50-plus score before being trapped lbw by pacer Nathan Coulter-Nile, who ended with 10 wickets in the five matches.
Sharma went on to register his 14th ODI ton during his 99-run partnership with Kohli, who made a sedate 39. He got to his hundred with a six off Coulter-Nile.
Leg-spinner Adam Zampa sent Sharma, who hit 11 fours and 5 sixes, and Kohli back to pavilion.
Kedar Jadhav, unbeaten on five, and Manish Pandey, 11 not out, then saw the team through.
Earlier, opener David Warner’s 62-ball 53 was not enough to inspire Australian batting as they ended on a below-par total after electing to bat first.
All-rounder, Hardik Pandya, who struck first by getting Aaron Finch out for 32, was given the man of the series award for his six wickets and 222 runs in the series.
“Lost wickets in clumps again. Have a few things to look at to try and improve and gain the consistent performances we’re after,” said a disappointed Smith.
“We’ve been outplayed and deserve to lose 4-1…India have got a very good balance. We have six or so days until the 3-match T20I series. We’d like to go home with a trophy,” he added.
The action now shifts to the three Twenty20 internationals starting Saturday in Ranchi.
