England aim for Bloemfontein repeat versus South Africa

Ben Stokes has warned South Africa that there will be no let-up in England's attacking approach in the second one-day international in Port Elizabeth.

England's batsmen were aggressive from the outset in the series opener in Bloemfontein with the top six all contributing as the tourists plundered 399-9 from their 50 overs.

Jos Buttler (105) led the way with a 76-ball century after Jason Roy (48) and Alex Hales (57) had laid a strong foundation at the top of the order as England recorded their second-highest ODI total.

A repeat performance on Saturday would move England closer to victory in the five-match series, with Eoin Morgan's side looking for a fifth-successive ODI win on a ground they have triumphed on just once before.

"If we can play the way we did the other day and emulate the way we went about everything, we should have a chance of going 2-0 up," all-rounder Stokes told a media conference.

"In the longer scheme of the series, if we can do that, then we'll put South Africa right under the pump.

"Since [last year's series against] New Zealand started, we've played exactly the same way and always wanted to post big totals and be aggressive."

South Africa will hope their bowling attack fares better than on Wednesday where they were taken apart by England.

Kyle Abbott looks set to boost their options after returning from a thigh injury, while Kagiso Rabada could also feature after being rested for the opener following his impressive performances in the Test series.

"I felt we did make a lot of mistakes [on Wednesday]," all-rounder Faf Du Plessis said. "We gave a lot of boundaries away.

"We weren't as disciplined as we'd want to be. So that is the focus for Saturday, to try to hold the pressure a little bit longer.

"Our bowlers need to be smarter, in Bloemfontein our bowlers only started bowling better a quarter into the game, we were smarter with our decision-making.

"It's important for us to try and do that from the beginning, not wake up 10 or 15 overs in the game to try and put our plans into place."

While their bowlers struggled, South Africa came close to a shock in their reply thanks to the unbeaten 132 from opener Quinton de Kock, but the rain curtailed their hopes and a score of 250-5 saw them fall short by 39 runs via the Duckworth-Lewis method.

De Kock reached three figures for the ninth time since November 2013 - a record only beaten by Hashim Amla who has 10 - and has claimed three knocks over 100 in his last four attempts.

The 23-year-old's form could be crucial to South Africas hopes of avoiding a third successive defeat in Port Elizabeth for the first time.
