What the heck does this question mean?
The minimum innings a pitcher needs for a perfect game is nine innnings
In MLB, yes. MLB's definition of a no hitter is: "An official no-hit game occurs when a pitcher (or pitchers) allows no hits during the entire course of a game, which consists of at least nine innings." So a pitcher could pitch a no hitter for nine innings or nineteen innings but if a reliever comes in and gives up a hit, the no hitter is over.

Pitch more shutout innings - that is, innings where you don't give up an earned run. ERA is calculated by taking the number of earned runs a pitcher gives up, dividing it by the number of innings he/she pitched, then multiplying the result by nine. So, for example, if a pitcher has six complete innings and gives up two earned runs, their ERA becomes three (2 divided by 6 is 1/3, 1/3 multiplied by nine is 3). This works over the course of a pitcher's career, so if a pitcher gives up six earned runs over six innings in one game, his/her ERA becomes nine. If he/she then pitches a complete game shutout (nine full innings, no earned runs) their ERA drops to 3.6 (as it is now six earned runs from fifteen innings).
Three games of nine innings to strike out 21 opposing players. 21 divided by 3 equals 7 strike outs per game on average.
There is a total of nine innings in a game of baseball. However, if the game is tied at the end of nine innings, then the game can go into extra innings.

Roger Clemens
He pitched for three innings and then the coach pulled him out. After nine innings of play, the score was tied. We finished only two innings before it started to rain.
