One of the biggest would be his service. At 196cm (6'5''), Bernard has quite excellent bodily parameters for a powerful service and also his service technique is, despite certain weakness in his legs and core, since years very solid. The below-presented photos are from the 2011 Masters Series tournament in..
..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...
Photos below show Casper's service during 2015 Orange Bowl. Even thought that his service was not that dominant back then, the most important basic characteristics of the Service 3.0 were already there at that time and provided a solid base for further development/improvement. The most important among them is the proper understanding of the "follow through 1" with a well-executed (well-pronounced) targeted pronation.
Naomi correctly fulfills all the essential Service 3.0 (of Tennis 3.0) requirements. Certain distinct improvements bringing higher margin and better efficiency would be still possible though. Some of the main aspects to work on are mainly around the rather arm-power forced pronation, which is quite normal when proper pronation was introduced to the player later in the career but should still become a bit more fluid (with better contraction-relaxation coordination) over the time to make an optimal....
From the point of the technique, Karolina has some excellent aspects of the Service 3.0 going most probably back to her early technical development stage in her junior years and also one little weakness leading to a lower margin at decisive (tense) moments like during her recent US.Open finals. Some of the main elements can be seen below..
Rebeka Masarova (*1999 / SUI) with her WTA ranking of #314 (as of July 18, 2016) is currently the world highest ranked player before reaching the 17th birthday. Rebeka, who won the 2016 French Open junior event a few weeks ago, considers service as her favorite stroke. She has Slovak and Spanish roots and is currently being coached by her mother. As all very successful Swiss female tennis players of the past over 20 years, Rebeka was developed largely privately outside of the regular Swiss Tennis Association program!
One of the most misleading tennis instructions is the imperative suggestion to lead the racket after the impact across to the non-dominant leg (left with the right-handed player) in the follow through of the service motion....
The principles of TENNIS 3.0, meaning the dominance of the body action in the strokes, can be applied practically for everybody at every age and level. Here featured senior player Jörg (65+ / SUI) is a life-long athlete, but late tennis starter. He was still able to learn in his sessions with the MBTA practically perfect serving motion where he generates the power of the ground and dominates the service by the energy from the body, which is being channeled into full upper-limb targeted pronation
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.....
