Trevor Bauer, a player from the professional baseball team DeNA, has stirred up controversy for his 'bat kick' antic during a recent game. Known for his unconventional actions, Bauer's latest move has sparked broad disputes and conversations in the Japanese professional baseball community. Critics argue his behavior breaks the unspoken rule of respect towards the opponent, albeit not being a violation of the formal game rules.

In Japan, there is a high regard for decorum and respect in every aspect of life, including sports. Bauer's 'bat kick' is seen as provocative and disrespectful by many, displaying a blatant disregard for the traditional etiquette of Japanese professional baseball. While not a legal issue, it strongly impacts the social reputation of the player.

The US and EU have a more relaxed approach towards non-traditional expressions in sports. Such behavior, unless breaching the rules of the game or being harmful, is typically viewed as a part of the player's style or personality. Nevertheless, respect towards opponents is also a valued principle in western sports, and actions that infritably cross that line may generate controversy.
