A very good baseball player will get three hits in every ten bats over their playing career. That means that they will not reach base and make an out seven times in every ten at-bats. A very good baseball player will strike out against good and sometimes, not so good pitching. Umpires can make bad calls that will put a batter behind in the count giving the pitcher an advantage or even call you out on a third strike on a bad pitch.
Umpires are human and make mistakes.
They are a part of the game. A very good baseball player will go to the plate with the attitude that he will get a hit. A batter has three strikes to put the ball in play. A very good baseball player will try to get three good swings at the plate and try to hit the ball hard somewhere. A very good baseball player will strike out getting three good cuts on occasion.
