Petra's favorite strokes are the service and the backhand, which is a great combination for her as a left-handed player. Her forehand is a bit mistake prone, as I did write about it in one of the previous articles here. Below, I am showing some important details from Petra's dominant service through the years, from her so far the most successful 2011 season and then some rather recent ones. And there are some developments to be spotted...
For many years, the service could have been considered as Martina's biggest weakness, mainly due to a suboptimal form of the pronation with the elbow staying rather too low and the racket traveling rather too much on the horizontal plane after the impact. Over the course of the years, Martina was able to improve it a bit and her pronation did look much better later in her career. With the elbow.....
..Marat's service belonged to the most dangerous ones on the tour. His body size of 193 cm (6'4'') was surely very helpful, but also his service technique was very solid and Marat was well fulfilling the Service 3.0 requirements. As unstable as Marat was in general, his 1st service percentage through his career was just 55%, but of those 1st services in, he has had a 75% winning percentage and also his ace probability of 67% was quite high...

This former top 10 player in both singles and doubles as well as twice Davis Cup Champion with the team of the Czech Republic belongs to the best servers on the Tour from the technical point of view. Despite his just average body size of 185cm (6'1''), he has a quite high career ace probability of 51% per game played.
While Serena's service is being considered as the best in the game, service of her sister Venus is not much behind..., besides the technique also her tall body of 185 cm (6'1'') helps. The situation that Venus tends (mainly under stress) to tilt her head to the left side before the impact might be one of the reasons for her rather higher double fault rate than the one of Serena...
In the below-shown serving point from Summer 2015, Stefanos demonstrates enormous technical capacities in his service, forehand as well as one-handed backhand, all of his strokes presented here fulfill the essential TENNIS 3.0 parameters.....
