Sydney, Jan 23 (UNI) Riding on twin tons of David Warner(113) and Mitchell Marsh (102 not out), Australia posted a challenging 330 for 7 against India in the fifth and final One-Day International (ODI) at the Sydney Cricket Ground here today. The hosts got off to a shaky start as they lost their Opener Aaron Finch(6) with just six runs on the board. After the fall of First wicket, Skipper Steven Smith (28) gave good company to Warner but his stay in the crease did not last too long and was caught at midwicket by Rohit Sharma. At the other end, Warner who seemed good at the crease smashed three sixes and nine boundaries in his 133-ball knock. The 29-year-old batsman was well supported in the other end by all-rounder Mitchell Marsh, who scored his maiden ODI ton and hit two sixes and nine boundaries in his 84-ball knock to power Australia to post a mammoth 330 . For visitors, Debutant Jasprit Bumrah (2-40) impressed in his first international outing alongside Ishant Sharma (2-60). UNI XC GAU 1406
