Top seed Ana Ivanovic tumbled out of the Pattaya Open on Thursday, losing in the first round to Japan's Ayumi Morita, while defending champion Daniela Hantuchova eased into round two.

Ivanovic, who has struggled to regain the form that saw her crowned world No.1 in 2008, lost in three sets (6-3, 5-7, 6-3) to Morita - ranked 47 places below Ivanovic.

Hantuchova survived a second-set scare from rank outsider Olga Puchkova and eventually won 6-1, 3-6, 6-0.
