Eoin Morgan struck a brilliant unbeaten century to lead England to a four-wicket victory over Australia in the first one-day international at the Rose Bowl in Hampshire on Tuesday. Man-of-the-match Morgan finished unbeaten on 103, steering hosts England to their target of 268 with four overs to spare after they had lost four early wickets. Earlier, Michael Clarke made a fluent unbeaten 87 to lead Australia to a competitive total of 267 for seven. Australia won the toss and openers Shane Watson and Tim Paine added 52 for the first wicket in perfect batting conditions. The second match in the five-game series is in Cardiff on Thursday
