What is the most important positions in baseball?

Pitcher and shortstop because many balls go to the shortstop and pitcher because they are pretty much in control of the game. Catcher is also pretty important because it is a tough job. For non competitive or leagues under 14 or so, 1st base is considered hard also.

Catching is a very tough job. Ive been catching for over 8 years now and you have to be ready for anything and know everything about the game including count and number of outs, also people on base. They have to always keep the ball in front of them and stop everything.
