Nov 17 (Reuters) - Australia's top order fired in unison to secure a six-wicket win over England with Dawid Malan's career-best 134 for the tourists in vain as in the first one-day international on Thursday. David Willey's unbeaten 34 was the next highest score by an England batter as the tourists went on to post a decent 287-9 at the Adelaide Oval. A 147-run opening stand between David Warner (86) and Travis Head (69) effectively laid the platform for Australia's comprehensive victory. The teams move to Sydney for the second ODI on Saturday to be followed by the third and final match in Melbourne on Tuesday.
