Australia beat India by 51 runs in the second ODI to take an unassailable 2-0 lead in the three-match series in Sydney on Sunday. Steve Smith (104) struck his second successive hundred of the series to set up the home side's win. India captain Virat Kohli played a fighting 89-run knock but, it was not enough after his bowlers conceded 389 runs. KL Rahul contributed with 76 runs. Australia had won the series-opener by 66 runs on Friday. The inconsequential third ODI will be played in Canberra on Wednesday. (SCORECARD | MATCH REPORT| NEWS)
