Re: Sam Stosur's serve - a technical discussion
The issue is where she tosses the ball. Because she so often uses her kick serve, she doesn't seem to toss the ball that often for an aggressive serve. That's probably just how it will always be. She often tosses the ball a little too far towards her left shoulder to develop a big slice serve with a lot of true slice on it. And since most of the women don't see a kick serve coming at them every day, they don't necessarily know how to handle it unless they're tall, which is why it's abysmal against women who are a little taller than 5'11" and up to Sharapova and Kvitova kind of height.
If she were able to, like Serena, find a more neutral toss and adjust her technique a bit, she would be able to hit more variety of spins. Her placement could do with some variation as well, but she doesn't have to change technique for that. She would just be better suited to just try some kickers to the forehand and to the body every so often. She so often, especially on second serves, will just hit to the backhand. She needs to do more variation in general by using that strong body and shoulder.
