After entering the world's top 100, 19-year-old Zheng Qinwen failed to make great strides forward 30, but instead encountered one round of tours and two rounds of tours in the tour, and the ranking stagnated at 70+.
So, why did Zheng Qinwen, who was praised for his outstanding physical fitness, solid bottom line shooting, good psychological quality, and was optimistic about the WTA, suddenly enter the bottleneck? The following set of data may illustrate the root cause of the problem.
In the entire WTA, the list of success rates, Zheng Qinwen actually ranked 8th from the bottom with 49.8%! The top 100 players with lower success rates than her are Mladenovic, Giorgi and Brehr.
Fans who have watched Zheng Qinwen's game should be deeply impressed by her extremely large range of serves, such a serve is almost a fight for luck, smashing into it may be directly Ace, but the probability of not being able to smash it is more than 50%. Once the game enters a critical moment, the change of mentality increases the chance of not being able to smash in, and the serve will become her weakness.
Therefore, the following Ace list, we just look at it, can not be a proof of her good serve.
In the 2022 season, Zheng Qinwen has issued 77 Aces, tied for sixth place with retired world number one Barty. In terms of the number of Aces per game, she and Barty are tied for first place, which is achieved against the background of the sharp decline in the number of Aces at Indian Wells and Miami.
In fact, through the observation of the two matches between Indian Wells and Miami, we can see that Zheng Qinwen is really timid in terms of serve, becoming less and less confident, and he is not afraid to send the second serve. As a result, more double errors came, so that on the double error rankings, she ranked 5th with 76.
Compared with Sabalenka, who issued 127 double errors through 12 games, Zheng Qinwen's 76 are small witches. However, considering that the opponent's overall serve quality is higher, the success rate of one shot reaches 60%, and the batting advantage brought out by one shot is also greater, you will find that the negative impact of Zheng Qinwen's double mistakes is significantly larger.
Changing the tee position and reducing the amplitude of movement may have reached an urgent time. After the action amplitude is reduced, the serve performance may be affected in the short term, but the stability is bound to be enhanced after a period of time, as long as the change of action does not affect the force, the number of Aces will not necessarily decrease in the future.
Like Wang Qiang, under the tutelage of the new coach, the amplitude of the serve has become very small. As a result, her serve concealment was enhanced, and the number of Ace balls increased. In the first round in Miami, she sent out 6 Aces, and the other times the serve worked well, making it easy to save serves.
Zheng Qinwen is only 19 years old, it is definitely easier to adapt to the changes in action than the 31-year-old Wang Qiang, at this time do not find a good serving coach to change the technique, when to stay?
Of course, for Zheng Qinwen, there are still many areas that need to be improved, such as mentality. Perhaps the speed of the previous jump was a little fast, so that she was full of self-confidence, had high requirements for results, and was eager to prove herself in a high-level event like the Crown.
This led to two matches, both of which she played very frizzily at key moments and eventually regretted losing. After losing to Kerber at Indian Wells Station, Zheng Qinwen's face was ugly when she shook hands, which proved that her mentality was indeed wrong. Psychological counseling, lowering expectations, and focusing more on every detail of the game, Zheng Qinwen needs to do these things.
