Sri Lanka appeared to be cruising to victory as Chamari Atapattu and Yasoda Mendis put on 103 for the opening wicket but England took five wickets for 54 runs to get right back in the game.
Eshani Kaushalya, dropped by Jenny Gunn on 10, kept Sri Lanka's hopes alive by striking five fours and three sixes in a crucial knock of 56 off 41 balls and although she couldn't quite see the job through, Surangika polished things off.
Kaushalya, who also bagged 2-49, was named Player of the Match and Guha told Sky Sports that she could well be one of the stars of this World Cup.
"She's been a prominent force within Sri Lankan cricket for a good number of years. She's got a lot of experience behind her," she said.
"Some of her shots are just pure brute force. The girls bowled quite a few full tosses and she capitalised on them. She put the bad ball away and hit several big sixes which were crucial in this match.
"I've always said it will be interesting to see how Sri Lanka play in this World Cup. They all became contracted players in 2010, so they have the opportunity now to train five days a week and they've improved on their skills massively.
"I remember in 2010 when we went to Sri Lanka that even though we came out victorious, they caused problems for us. They've got an excellent skill-set and we've seen today that they've got a lot of fire in their belly.
"They are used to these sub-continent conditions, the spinners bowled extremely well today and the batting department - which they've always said is their weakest suit - came good."
