Australia batting great Ricky Ponting has said the top-order must deliver "big runs" after the world champions went 1-0 down in a one-day international series away to England. The 2019 World Cup hosts beat Australia by three wickets in the first of a five-match campaign at The Oval on Wednesday. Although England stuttered during their chase, Australia were always in trouble after being dismissed for just 214, with spin again proving their undoing as England specialist slow-bowlers Moeen Ali and Adil Rashid accounted for five members of their top seven between them.

Glenn Maxwell (62) and Ashton Agar (40) tried to repair the damage but their sixth-wicket stand of 84 couldn't change the course of the game. Ponting, one of the outstanding batsmen of his generation, has joined the backroom staff of new Australia coach and former Test team-mate Justin Langer for the tour. Reflecting on Australia's slump to 90 for five on Wednesday, Ponting said: "It highlighted again the importance of our top-order batsman taking responsibility and getting some big runs."
