"That's not the answer to repeated training" Throw a lot of balls for good control? Korea Baseball Prejudice Breaks... U.S. Baseball Noting Variability [Maybe baseball says ②]

It has been taken for granted in the Korean baseball community for a long time to say that one should give up his ball control to some extent. The reason was that if the power went in, the control would fly.

In addition, for good control, only a certain pitching form and a lot of repetitive training were considered as solutions close to the correct answer. That said, when he gave up his restraint, his control had to increase to some extent. But the relationship was not necessarily inversely proportional. In addition, pitchers with constant pitching form did not necessarily boast outstanding control.

In this regard, an interesting research report was recently published at the American Baseball Research Association (SABR). According to The Interaction of Biomechanics and Command, known as a famous sports training center in the United States, the most important thing in control is not "simple repetitive training," but "variability." Driveline received the "Mike Marshall Pitcher Biomechanics Research Award" at this year's SABR for this report.

It has destroyed the widespread prejudice in the Korean baseball community that "we must give up our restraint for good control." According to the report, restraint and control are "traded off (if you get one, you lose one)." It's not a relationship. Rather, it is defined that overwhelming restraint is 'insurance' that covers even the mistakes of control, and control is the product of 'adjustment ability' rather than mechanical repetition. Nowhere was it said that the restraint should be abandoned in order to improve control.

Prior to the start of the study, Driveline said, "It was widely known that command (the ability to throw exactly at the point required by the catcher) was important, but quantified information was lacking. Almost all command information published so far has been based on results. As a result, command research lagged behind confinement research by 20 years," he said.

"The main training method (known so far) related to commands was simply to throw more and focus exactly on the right point. Each coach had his own idea of what a good mechanism was. The most consistent thing to say was to ask pitchers for repetitive mechanisms, and there was no explanation for what to repeat. This is what we want to solve with research," he clarified the subject.

Kyle Hendricks (37, Los Angeles Angels), Darvish Yu (40, San Diego Padres), and Ben Joyce (26, Los Angeles Angels) were introduced as examples to understand what the criteria for good control are. Hendricks has a slow ball of about 140km/h, but he is the best ball control pitcher in the league. On the contrary, Joyce is a young pitcher who throws a fast ball of 164 km/h, although he is not excellent at controlling the ball. Darvish is evaluated as a pitcher with both fast speed and compliance control.

The driveline accumulated data by measuring the distance between the pitcher's intended point and the actual point where the ball was inserted. Their release points (where the ball is placed) and pitching mechanisms were also measured. As a result, it was not that the "player with a certain form like a machine" that was commonly thought of was excellent in control. The concept that appears here is 'Bernstein's Hammer'. A skilled blacksmith has a slightly different hammer-wielding trajectory each time, but the final strike point is always accurate.

This is because the body detects errors and corrects the trajectory in real time. The same goes for pitchers. The report says that it is the essence of good control to instinctively correct the fine balance deviation that occurs at the beginning of the pitching motion and insert the ball into the final destination. According to the data, pitchers with good control fine-tune the speed of muscle rotation from pitch to pitch just before placing the ball. Repeated training is not entirely wrong. However, if Korea focuses only on creating a certain pitching form through repeated training, the U.S. should develop a sense of correcting errors.

Driveline says that the training method is also effective to throw different weights of the ball or change the slope of the mound, rather than just throwing it in the strike zone a lot. In other words, more systematic changes are needed in training to increase control. Of course, there is no need to feel humiliated just because Korean baseball is behind. Training for good control is still an active topic in the U.S. Major League Baseball, which is at the peak of modern baseball.

Amid the recent sluggish international competitions, the Korean baseball community is also feeling the need for change. However, the reality is that they are still torn over the direction of the change. In addition, experience-based teaching methods also play a role. There were also voices expressing regret over the uniform guidance method of the site.

A trainer who has raised several KBO players told Star News, "Our country's training methods so far have stopped at pointing out to pitchers in the bullpen, such as 'low arms', 'too short tempo', and 'the width of the stretch is too small.' "It's like making him throw a lot of balls to raise his speed, and jumping a lot to gain muscle. The U.S. and Major League Baseball train with purpose according to individual characteristics of each player. For example, in order to increase the judgment of infielders on batting, Korea plays fungo. However, the U.S. does a separate drill exercise to increase the judgment of the batting itself," he added.

Until now, no field official has answered the question, 'What should I do to have good control?' Some said that he had to throw a lot to know, and others said that control was also a talent. According to this driveline's report, the answers from the field leaders' experiences were not wrong. In order to have good control, he needed natural senses and repeated training.

However, in order to reach the same conclusion, it was different in the United States that the problem was quantified through data and proved that control was an area that could be improved through systematic training. Like those who solved the secret of their control, which was like a black box, it is time for Korean baseball to provide an accurate basis for what went wrong with the player and give directions.
