Perth, Australia: Australia comfortably defeated India by 7 wickets in the opening match of the three-game ODI series at the Optus Stadium, chasing down a revised target of 131 in just 21.1 overs.

India, invited to bat, were restricted to 136-9 off 26 overs in a rain-affected innings in the first ODI against Australia in Perth on Sunday.

In a frustrating start to the three-game series, persistent rain forced the players from the field on multiple occasions, frustrating the Indians, who struggled to build any momentum.

India's top order collapsed with several key players falling cheaply, including Virat Kohli, Rohit Sharma and skipper Shubman Gill.

Australia’s innings was anchored by Mitchell Marsh, who remained unbeaten, while newcomer Matt Renshaw held firm as they reached the target with ease.

Asked to bat first, India laboured to a sub-par 136 for 9, after the match was revised to 26 overs for a side courtesy several rain interruptions, leaving the hosts to chase a DLS target of 131, which they duly reached in 21.1 overs.

Travis Head fell to Arshdeep Singh early, slashing the left-arm pacer to Harshit Rana at deep third man, and Matthew Short too walked back without any significant contribution.

The Indian pacers could not replicate the control of their Australian counterparts, offering plenty of freebies to the hosts' batters.

Marsh fed on them with glee, crunching a six each of all three. An inside-out smash off Siraj over covers was the highlight.

Philippe gave his captain ample support with a busy knock, and his dismissal was a minor irritant in Australia's march, which culminated in them taking 1-0 lead in the three-match series.
