Osaka eyes Naomi Slam

MELBOURNE, Jan 27 (AFP): Newly-minted Australian Open champion Naomi Osaka said she was not satisfied with back-to-back majors Sunday and hoped to complete a "Naomi Slam" after her success at Melbourne Park.

The bubbly 21-year-old laughed off suggestions her meteoric rise had put her under pressure, saying she was relishing the big time after rising from 72 in the world to number one in the past 12 months.

Japan's Osaka becomes the first Asian to hold the top ranking after downing Czech Petra Kvitova in a tight final on Saturday night and adding the Australian crown to the US Open title she won last year.
