A century stand between Amy Jones and Tammy Beaumont saw England to an eight-wicket victory in Colombo to complete the sweep
Amy Jones made it three fifties in a row as England completed a 3-0 series whitewash over Sri Lanka with an eight wicket victory in Colombo.
Jone (76), who struck 79 and 54 in the first two ODIs, shared an opening stand of 127 alongside Tammy Beaumont (63) as the tourists comfortably chased 175 in 26.1 overs.
Kate Cross removed both Sri Lankan openers early on and the hosts struggled to recover from there.
Anya Shrubsole and Alex Hartley both picked two wickets of their own as Sri Lanka were bowled out for 174 in the final over of the innings.
The victory makes it seven in a row for Heather Knight's side who climb to second place in the ICC Women's Championship.

The skipper said: "It was a really professional performance. It's incredibly hot out there and the bowlers did so well to maintain their discipline and keep Sri Lanka down to that total.
"We've done brilliantly to make it look comfortable because you have to work very hard to make it look straightforward. That's what we do all the hard work for, and you can see the increased fitness when we maintain our standards in conditions like that.
"The batters, especially the two at the top, have been fantastic in this series and I'm proud that we've kept our momentum and kept being clinical.
"It's been a long tour for us and obviously those first two defeats to India were disappointing but it says so much about the team's character that we've fought back like we have to win seven in a row."
