PORT ELIZABETH, South Africa (AP)

James Anderson took five wickets and Jonathon Trott hit an unbeaten half-century yesterday to lead England to a seven-wicket win over South Africa and an unassailable 2-1 lead in the one-day international series.

The Proteas were bowled out for 119 in under 37 overs after winning the toss with Anderson taking a career-best 5-23, and South African-born openers Trott (52 not out) and Andrew Strauss (32) starred with the bat as England won with almost 19 overs left.

Anderson, who won the Man-of-the-Match award, said having a pitch that helped the bowlers had made a difference at St George's Park Stadium.

"You couldn't bowl short in Cape Town, the wicket was flat. Here we bowled good lines but we had a wicket which helped us," he said.

The last ODI in the five-match series is Friday in Durban. The first match was washed out.

Strauss became the first of off-spinner Johan Botha's two wickets when the ball hit his pad off an attempted cut shot and he was adjudged lbw. Strauss faced 59 balls and hit six fours.

Botha struck again within five balls as he induced Kevin Pietersen on 3 to flick a ball straight to A.B. de Villiers at midwicket. Botha finished with2-22, while Ryan McLaren found in-form Paul Collingwood's outside edge for a catch behind.

Collingwood's departure for 2 meant England had lost 3-9 in five overs, but Trott and Eoin Morgan (28 not out off 40 balls) steered the visitors home. Trott hit seven fours in 77 balls, while Morgan reached the boundary five times.

South Africa's innings started badly, with Smith lasting just four balls before he was trapped in front for 2 by Stuart Broad in the second over.
