David Warner slammed 70 off 36 balls in his 100th Twenty20 international and Adam Zampa grabbed three wickets as Australia beat the West Indies by 11 runs in the opening clash of their three-match series on Friday. The hosts crunched 213-7 after being sent in to bat on a windy and cold Hobart evening. The visitors put up a valiant fight but they could only manage 202-8, with Zampa taking 3-26. Warner, who became only the third man after New Zealand's Ross Taylor and India's Virat Kohli to play 100 internationals in each format, hit 12 fours and a six in his explosive knock to anchor the Australia innings.
