England have won the toss and will bowl first in the fourth one-day international against South Africa at Lord's today.
The series is poised evenly at 1-1 after the first match was rained off, before a victory apiece at The Ageas Bowl and Kia Oval.
England's triumph at The Oval meant they retook top spot in the ICC ODI rankings from South Africa, who, if they win today, can move into first place.
England: Cook, Bell, Trott, Bopara, Morgan, Kieswetter, Tredwell, Patel, Anderson, Dernbach, Finn
South Africa: Smith, Amla, Elgar, De Villiers, Du Plessis, Duminy, Parnell, McLaren, Peterson, Steyn, Tsotsobe
