Ivanovic too strong for Stosur

Ana Ivanovic demonstrated some of the form which made her world number-one as she booked her place in the fourth round at Wimbledon.

Ivanovic arrived at Wimbledon last year as the French Open champion and top of the world rankings, but lost in the third round to Chinese wild card Jie Zheng and then failed to win back-to-back matches in her next five tournaments.
