ICC Women's World Cup, Manuka Oval, Canberra:
England 277-5 bt Sri Lanka 177-7 by 100 runs
Taylor's excellent 101 set up England's victory
Claire Taylor struck a superb century as England's women opened their World Cup campaign with a comfortable 100-run victory over Sri Lanka in Canberra.
Taylor's 101 off 95 balls followed a solid 80-run opening partnership between Caroline Atkins (50) and Sarah Taylor (38) as England posted 277-5.
Laura Marsh then took 3-32 as Sri Lanka fell short in their run chase on 177-7, Suwini de Alwis top-scoring with 37.
India opened their campaign by cruising to a 10-wicket victory over Pakistan.
Their performance will have given food to thought to England who take them on in Group B in Sydney on Tuesday.
Taylor's knock, which included 10 fours, was her eighth ODI century and set a solid platform for Charlotte Edwards' side, until she departed in the 48th over.
Edwards also contributed 27, while Lydia Greenway was unbeaten on 32.
Taylor, who also notched hundreds in previous World Cup meetings with Sri Lanka in 2000 and 2005, was delighted to start the competition in such fine touch.
"I'm pleased to get some runs early in the tournament," she said.
"The Sri Lankans must be sick of the sight of me, but all due respect to them for keeping going in the field with the ball and attacking us with the bat.
"I'm looking forward to playing against India on Tuesday - which I think could be the key match in our group."
England head coach Mark Lane added: "Claire played brilliantly, using all her cricket nous and experience.
"The opening bowling lacked penetration and at times the fielding was lacklustre. We must show improvement in all three disciplines before we take on India."
After winning the toss in Bowral, India dismissed Pakistan for 57, with only two batsmen reaching double figures.
Rumeli Dhar was the pick of India's bowlers, claiming three wickets for just seven runs off eight overs, including five maidens.
Anagha Deshpande, made 26 and Anjum Chopra 17 as India eased to their target in 10 overs.
England, bidding to win their first World Cup on foreign soil, are also drawn with Pakistan in Group B of the eight-team tournament, while holders Australia are in Group A.
South Africa, the West Indies and New Zealand make up the other teams in the competition.
Australia, who won their fifth World Cup when they beat India in the 2005 final in South Africa, are once again favourites for the title.
They open up their defence against New Zealand - winners in 2000 - in North Sydney on Sunday.
Three teams from the two groups will go through to the Super Sixes and the top two will contest the final in North Sydney on 22 March.
