Mohali, Sep 22 : Shubman Gill and Ruturaj Gaikwad hit fifties at the top, followed by captain KL Rahul and Suryakumar Yadav notching up half-centuries in guiding India to five-wicket win over Australia in the ODI series opener, here at PCA Stadium on Friday. After veteran fast-bowler Mohammed Shami bagged the second five-for of his ODI career and propelled India to bowl out Australia for 276, the pitch seemed to have eased out a bit in the second innings, making the path of taking a 1-0 lead easier for the hosts. In the chase, Gill and Gaikwad combined to share a stand of 142 runs for the opening wicket. Gill, playing his first international match at home, made 74 off 63 balls while Gaikwad scored 77-ball 71, also his first ODI fifty. After the duo followed by Shreyas Iyer and Ishan Kishan fell, Rahul stepped up under pressure yet again, scoring a 63-ball 58, with four boundaries and a match-winning lofted six to seal a clinical win with eight balls to spare. What would have greatly pleased the team management was the restraint in shot-selection and calmness in the situation shown by Suryakumar, while making a 49-ball 50, a much-needed third half-century in the format to ease questions on his 50-over adaptability.
