A ride and thrower brought by ABS? Unsolved 'Taeng-Taeng-Ball' Mystery

This season, when the world's first automatic ball determination system (ABS) was introduced, professional baseball is 'Tago Tugger'.
His ERA stood at 4.86 in the league, jumping from 4.14 in the last season. His batting average also stood at 0.276, slightly up from 0.263 in the previous season.
KBO said it will expand the strike zone by 2cm by introducing ABS. It is a strange season where the strike zone has expanded and the batter's strength stands out.
■How advantageous is the consistent ABS zone for the batter?
One of the reasons that the introduction of ABS has given batters an advantage is the consistent application of the zone. In the past, strike zones were different for each umpire, and batters had less time to adapt to this zone during the game than pitchers.
In addition, since the ABS zone changes according to the height of the batter, the pitcher must compete according to the different zone for each batter. On the other hand, batters have a certain zone regardless of the opposing pitcher. Unlike in the past, batters have an advantage in the fight to grasp the zone.
However, this does not appear in the figures.
While his ball count increased by 0.4 percent per batter's box, his strikeout rate increased by 1 percent. Among the total strikeouts, his strikeout rate also increased by 2.7 percent. This season, ABS has strictly caught even the corners of the zone, leading to several scenes in which batters are struck out while watching strikes.
The probability of swinging at the ball inside the zone and the probability of swinging at the ball outside the zone are also the same as last season. Based on figures, ABS and strike zone did not significantly affect the game.
■The first reason for the increase in home runs...Bouncy ball mystery?
He hit 924 home runs last season and 792 this season as of July 3. Considering that the first half of the season is not over yet, the pace is fast.
If one home run was made in about 61 at-bats last season, one home run was made in 42 at-bats this season.
The increase in home runs (HR/FB) compared to fly balls is particularly noticeable. The HR/FB ratio increased from 4.4 percent last season to 6.7 percent this season. This means that once the ball hits the road, it will become a home run more often.
There are many reasons, but first of all, the speed of hitting has increased. This season's batting speed increased by about 2km/h compared to last season.
The in-play batting average (BABIP%) also increased slightly, but it does not seem to have had as much of an impact on scoring as home runs.
If the batting speed has increased and the number of home runs has increased, you can consider the rebound coefficient of the official ball.
According to the results of the KBO's occasional inspection of official ball, however, the rebound coefficient was slightly higher in the first round, but there was no significant difference from last year in the second round. The rebound coefficient was within the standard range in both the first and second rounds.
■What is the reason for the mysterious Tagotjeo?
① 'High Zone' Becomes Generous...More home runs due to high ball games
This season, many commentators and players are expressing their opinions that the ABS zone is tolerant of the high side of the ball. On the other hand, it is pointed out that the low ball has become a bit rough.
As the zone has grown upward, it seems that the scene where pitchers target the top of the zone and compete with batters has increased. Some argue that the number of home runs has increased due to the increased number of high ball games.
This season, pitchers often catch strikes with high breaking balls. However, such high breaking balls lead to long balls if the ball control is slightly off.
②Missing "Going Home Zone"? There is no mercy on ABS.
Among baseball fans, there is a so-called "work zone." This means that if the score gap widens and the game tilts unilaterally, the umpire's strike zone widens for faster progress.
It is questionable whether this is real or not, but at least ABS is an exception. Even if a weak pitcher comes up to handle the loss, John is the same. He claims that consistent John brought in the pitcher's riding without mercy from ABS regardless of the situation.
③Reliability of the rebound coefficient test?
Three shots (36) were used in the second round of the KBO's official ball test. It is known that an average of 10 to 12 balls are used during nine innings in baseball games.
In addition, as each stadium has different storage conditions for official balls, the coefficient of repulsion may vary depending on which stadium the samples were collected.
Finally, it is not to use all the official balls that were the subject of the first test in the actual game and then use the official balls that were the subject of the second test. 먹튀검증
According to KBO officials, the official ball is delivered to the club several times, but the club does not necessarily use the official ball in the order of first-in-first-out.
