What does are you a pitcher or a catcher mean?

Answer 1

Of the nine positions in Baseball, pitcher and catcher are the 2 most critical, requiring the greatest level of skill. These 2 players touch the ball on virtually every pitch and therefore have the greatest impact on the outcome of the game. So when a coach is assembling his team, he'll often ask prospective players if they are a pitcher or catcher because those are the first positions he'll want to fill.
