Unlike other sports, professional baseball has a long season with numerous games, more akin to a year-long marathon, where players spend almost every day shuttling between training and matches:
Take SoftBank for example. Even if they clinch first place in the Pacific League during the regular season, sweep their opponents in the climax series and Japan series to win the championship, they still have to play more than 150 games over at least seven months in a season, which is no small pressure.
Within this, a starting pitcher who can stand firm on the team usually has to pitch in more than 20 games in a season, while the team's ace has to pitch 25 to even 30 games or more. As for the hitters, who consume relatively less, many play every game without missing any.
However, the human body's peak athletic state is precisely a physiological phenomenon that cannot be maintained for the entire season, an insurmountable law of nature.
