Spain began their Women's World Cup campaign in scintillating fashion by beating Costa Rica 3-0 in their Group C opener on Friday, thanks to an own goal and first-half strikes from Aitana Bonmati and Esther Gonzalez at Wellington Regional Stadium.

The teams had played out a draw when they faced each other on their World Cup debuts in 2015 but Spain are now sixth in the women's rankings and it showed in their technical dominance as they scored three times in a six-minute blitz.

Twice Ballon d'Or winner Alexia Putellas was named among Spain's substitutes as she makes her way back to full fitness, but their most-capped player was not needed in the first half as Bonmati and Esther ran riot in Costa Rica's box.

Costa Rica goalkeeper Daniela Solera saved a first-half penalty, but Spain were never threatened at the other end and went top of their group ahead of Japan's game against Zambia on Saturday.

In the pouring rain, Spain dominated possession and pegged Costa Rica back inside their own half right from kickoff, with Athenea del Castillo narrowly firing wide while Ivana Andres saw her header tipped over the bar.

But the relentless pressure finally paid off in the 21st minute when Gonzalez's cross was turned in by Costa Rica's Valeria del Campo.

Only two minutes later Spain quickly regained possession and a fine cutback set up Bonmati, who smartly evaded two defenders to curl home Spain's second.

Costa Rica could have conceded more if not for the heroics of Solera in goal as she made timely interventions and reflex saves.

However, she could do nothing as Gonzalez scored the third from a rebound off the post.

A point for Nigeria

Goalkeeper Chiamaka Nnadozie helped Nigeria secure a valuable 0-0 draw against Olympic champions Canada in their opener in a result that threw their group wide open.

Nnadozie saved a penalty in the 50th minute at Melbourne Rectangular Stadium, denying Christine Sinclair from the spot with a leap low to her left as the Canada skipper missed out on becoming the first player to score in six World Cups.

The teams were left with a point each, trailing Group B leaders Australia by two.

Both sides had their chances but Sinclair was perhaps the most frustrated, having also missed an opportunity in the ninth minute.
