that's good. if she has indeed improved her serve, she has to use it all times. including serving out a set or a match. and i expect her to start beating clijsters, kuznetsova, mauresmo, petrova, and other top 10 players in two sets.
elena dementieva, serena williams, caroline wozniacki, ana ivanovic
david nalbandian, rafael nadal, andy murray, gael monfils, jo-wilfried tsonga
