How can a player get to 1st base without hitting a ball?

Answer 1

Most if not all players have gotten to first base without hitting the ball. Most if not all receive a 'walk' (pitcher throws four pitches that are called balls by the umpire) and some have been hit by the ball thrown by the pitcher. In either case, the batter gets to take first base without ever hitting the ball.

Answer 2

Hit by pitch, base on balls, catcher's interference, passed ball or wild pitch on the third strike

Answer 3

base on balls, or hit by pitch.
