I just want to keep improving and keep putting the ball in the right areas and hopefully the pace will come with that.
England have not won a series in South Africa since 2016, and Filer is determined to change that record.
We’re so close to potentially winning a series in South Africa and it would be a great achievement for us, she said.
But we know that South Africa are a strong side and we can’t underestimate them, we have to be at our best to get the win.
England will be looking to Filer to continue her impressive form and help them secure the series victory in the final ODI match.
