A runner at second with no one on first does not face a force out since the batter will have the choice of proceeding to third or staying on second. A fielder causes the force by tagging the base that runner needed to advance to. A fly out occurs on a fly ball that is caught. Any two outs that occur during the same at bat. The pitcher performs what is arguably the most important role in a game.
Pitchers control the game's tempo and can be credited with a team's win or loss.
The goal of any pitcher is to shut down the opposition and prevent them from scoring any runs. The pitcher pitches balls, strikes, or hit balls. The pitcher tries to pitch the ball into the strike zone, the area over home plate between a batter's knees and mid-chest area. Pitches that fall outside of the strike zone and are not swung-on, are considered balls. Four balls, and the batter walks, three strikes, and the batter is out.
