England captain Alastair Cook won the toss and elected to field in the fourth one-day international (ODI) against Australia in Chester-le-street on Saturday.
England made two changes from the side that won the second ODI at The Oval by six wickets to go 2-0 up in this five-match series -- Wednesday's third ODI at Edgbaston was washed out without a ball bowled and no teams declared.
The hosts brought in left-arm spinner Samit Patel for his first match of the series in place of off-spinner Graeme Swann, rested for the final two fixtures of this series as he recovers from an elbow injury.
And James Anderson returned from a groin problem in place of Surrey seamer Jade Dernbach, out with a side strain.
Australia also made two changes with left-arm quick Mitchell Johnson and spinner Xavier Doherty dropping out and seamers James Pattinson and Ben Hilfenhaus coming into the side.
