India's young openers ensured an easy five-wicket win over Australia after pacer Mohammed Shami took five wickets to restrict the visitors to 276 in the first one-day international in Mohali on Friday.
Stand-in skipper KL Rahul, who won the toss and chose to field first, hit an unbeaten half-century and stitched a key 80-run stand with Twenty20 sensation Suryakumar Yadav (50).
The duo stabilised the innings as the hosts lost four quick wickets, including openers Ruturaj Gaikwad (71) and Shubman Gill (74), after their 142-run opening stand.
The Indian openers looked at ease against the varied Australian attack led by skipper Pat Cummins who returned for the three-match ODI series after a wrist injury.
Australian legspinner Adam Zampa removed both openers to finish his spell with 2-57.
After Gaikwad's wicket at 142, India also lost Shreyas Iyer (3), Gill, and Ishan Kishan (18) to slip to 185 for four.
Flamboyant Yadav fell to Sean Abbott with only 12 runs needed, trying to hit India to the winning target of 277.
SHAMI SHOW
Earlier, Shami gave India the perfect start by dismissing dangerous Mitchell Marsh in the very first over.
Opener David Warner and veteran Steven Smith stabilised the Australian innings after Marsh's wicket with a 94-run stand before Warner fell to the left-arm spin of Ravindra Jadeja.
Smith fell soon after to leave visitors struggling at 112 for three, and India's veteran offspinner R Ashwin removed a well-set Marnus Labuschagne (39).
A passing shower briefly disrupted play before a key partnership between Josh Inglis (45) and Marcus Stoinis (29) began to take the initiative from the hosts.
But Shami returned to remove Stoinis, Matthew Short, and Sean Abbott and finished with 5-51.
Cummins remained unbeaten after a nine-ball 21 as Australia set the hosts a below-par target.
Both teams see the three-match ODI series as a key preparation for their World Cup campaign next month.
