Be the Referee: Fair or Foul Ball?

May 14, 2015

This week, MHSAA assistant director Mark Uyl explains how baselines come into play when deciding if a batted ball is fair or foul in baseball and softball.

Below is this week's segment - Fair or Foul Ball? - Listen

Today’s segment is going to start with a quick “You Make The Call” question.

Baseball batter up at bat hits a line drive directly back toward the pitcher’s mound. The ball hits off the pitching rubber or the pitching plate, and rebounds directly into the first base dugout. 

Fair or Foul Ball?

Baseball and Softball are unique in that these are two sports where the lines are actually considered to be in play. A ball hitting the chalk line in Baseball or Softball is a Fair Ball, to where in a basketball game, that player would be considered out of bounds.

Now back to our question – that would be considered a Foul Ball because the ball never settled or passed first base or third base in fair territory.

Be the Referee: Injured Runner

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – Injured Runner - Listen

We have a baseball scenario for you today:

Your team is down one in the ninth and you are standing on second base when your teammate hits a mammoth game-winning home run.

You are understandably excited. But – in your excitement of rounding the bases – you trip on third base and tear your Achilles tendon. You are unable to get up and continue to home plate.

The home run hitter stops at second base – unsure of where to go.

Because you are entitled to the next base on a home run, your team is able to bring in a pinch runner for the injured runner, and that person can finish running the bases and cross home plate.

The home run hitter can then continue rounding the bases and score the winning run.
