England notched a three-wicket victory over Australia in a low-scoring first ODI at The Oval on Wednesday.
Thanks to 69 from skipper Eoin Morgan and 50 from Joe Root, the hosts scraped past Australia's 214 with three wickets in hand and six overs to spare, despite the visitors making a fight out of their meagre total.
Earlier, Glenn Maxwell (62) and Ashton Agar (40) were the only batsmen to make more than 24 as Australia were bowled out with three overs left in their innings.
Off-spinner Moeen Ali took a trio of top-order wickets on the way to figures of three for 43 as England, the number one-ranked side in ODIs, looked to bounce back from their shock six-run loss to Scotland in Edinburgh on Sunday.
This five-match series was Australia's first in international cricket since their controversial 'ball-tampering' tour of South Africa led to year-long bans for former captain Steve Smith and his deputy, David Warner, with batsman Cameron Bancroft suspended for nine months after applying sandpaper to the ball during the third Test in Cape Town.
