What does no-hitter mean in baseball?

First off: A pitcher pitches from the beginning of the game until the end of the game. It means that one pitcher on one side of a game insists on completing the game. Because generally, a whole game of 9 innings requires about 110 to 150 pitches, which consumes a lot of physical strength. When the physical strength is not enough, it is not good to control the ball, and it is easy to be knocked out. It is said that the Heisei monster Matsusaka once pitched 17 innings and consumed 250 balls. His physical fitness was 6 times that of ordinary athletes. The number of completed games must be recorded in the player's career record.

Let’s talk about several scoring-related factors

A shutout: A shutout means that one of the two sides finished the game without scoring a single point. For example, 6:0 and 2:0 are both shutout games. What you said about losing points is the same concept. Generally, if there is no score lost after entering 7 games, you have to strive to seal the game, because this is also counted as a record.

No-hitter: Going on base mainly relies on hits. This is easy to understand. A no-hitter game means that the opponent does not have a hit, and no one gets on base due to his own hits. This is even more difficult than a shutout, because a shutout can have hits, as long as you don't score.

Perfect game: also called perfect game and perfect game. In addition to hits, walks, defensive errors, pitcher fouls, and hits can also put batters on base. If there's a no-hitter, and there's none of that, then it's a perfect game. However, there is a prerequisite that the pitcher must complete the throw. This is very rare. On average, it occurs once in more than 20,000 MLB games. So far, it only occurs in 20 games. In a perfect match, the president would send a congratulatory message. Generally, if there are no hits or errors by the end of the game, the leading team will try to complete a perfect game.
