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...
..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...
Ivo Karlovic (*1979 / CRO) belongs to the most dominant servers/servicemen in the history of tennis and his more than 11,500 aces served throughout his professional career (as of December 2016) on the tour are a record hardly to be matched. At the height of 211 cm (6’11”) and weight of 104 kg (230 lb), Ivo...
Ying-Ying Duan (*89 / CHN) can be at her age of 27 years hardly considered as a young tennis prodigy, but this relatively new entrant into the WTA top 100 could eventually become a factor in the women's tennis. At her height of 186cm (6'1''), the service can be considered as her biggest weapon. Her service surely has already quite some potential, but certain improvements could bring even better serving efficiency and higher margin along.
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..
