There seems to be another reason for injuries to major league pitchers, with officials counting the pace of the game finding an unprecedented number of throw-ins. For the first time since 2017, the number of throw-ins in the major leagues has surpassed that of in-bounds, with 28.4 per cent of throw-ins taking up last year (27.2 per cent of in-bounds). In other words, most of the pitcher's energy is consumed by throw-ins, which increases the probability of injury if they throw every ball so hard.

In 1989, 27 per cent of throw-ins and 34.3 per cent of in-bounds were taken. One reason for the decline in in-bounds is the increased pressure of the pitcher, which increases the number of hitters throwing away. In this case, a hitter who is good at picking the ball can make pitchers very painful, such as Juan Soto, the "700 million man" of the Mets.

Former Dodgers pitcher Ross Stripling said, "Pitchers like me, who aren't good at letting hitters swing away, usually start with the strongest shots, unlike some pitchers who save their tricks for the third good shot." If I run into Soto, he's going to throw my best balls out of bounds, pick out my curveballs, he's going to use me 10 balls on a bench, and when he goes into the zone for the second time, I know it's bad, he's seen my best balls, and I'm no longer in the mood for him. ”

Cubs pitcher Jameson Taylon remembers the 2017 matchup against Reds hitter Joey Votto, who grabbed the lead three times, but Voto hit a total of 15 throw-ins and didn't go out, and finally three consecutive hits were four bad escorts, and he alone consumed 31 goals for Tayon. "He deliberately played the throw-in, and his skill ruined my start."

The hitter actually wanted to hit the ball out, and Taon discussed this with his teammates, and some people just couldn't see the ball clearly and were forced to take out the stick on the good ball to protect themselves, and the reason why they couldn't see clearly was mainly because the ball was too fast. The major leagues changed their rules in response to this matter, and the National League began to consider throw-ins as good in 1901 (1903 in the American League), and in the seasons before that, throw-ins were not counted as good balls, giving particularly sticky hitters an unfair advantage.
