INSTANT REPLAYS 

Instant replays is a library of videos that we think you will learn from observing. 

Below is a game that will demonstrate why it is so important to not only know the rules, but know the situation. Attached is a video from a Major league game in Japan game. It was the bottom of the 9th inning with bases loaded, one out, (infield fly situation) and the winning run on 3rd base. The plate umpire ruled the runner out at home for a force play.
Watch the video and see the results.
