MURCIA – Naomi Osaka's return to Japan's Fed Cup team after a year's absence turned sour on Friday as the world number 10 suffered a thrashing at the hands of Spain's Sara Sorribes Tormo.

The two-time Grand Slam champion was expected to give Japan a huge boost in their bid to overcome five-time champions Spain at the La Manga Club near Murcia, but lost 6-0 6-3.

Osaka, whose Australian Open title defence was ended by 15-year-old Coco Gauff, racked up 50 unforced errors in a torrid display against the world number 78.

Carla Suarez Navarro, playing in her last home tie for Spain, then beat Misaki Doi 6-3 6-4 to put Spain 2-0 ahead going into Saturday's reverse singles.

Spain need to win just one of Saturday's three rubbers to book their place in the inaugural Fed Cup Finals featuring 12 nations in Budapest in April.

Holders France, runners-up Australia, wildcards Czech Republic and hosts Hungary will definitely be involved in the revamped event, leaving eight others to book their places in this weekend's qualifiers.

Switzerland also moved 2-0 ahead in their tie against a much-weakened Canada side in Biel.

Jil Teichmann battled past teenager Leylah Annie Fernandez before Belinda Bencic beat Gabriela Dabrowski who was a late replacement for Eugenie Bouchard who pulled out with injury.

Canada were also unable to call upon U.S. Open champion Bianca Andreescu for Friday's singles.
