A rainout refers to a game that is canceled or stopped in progress due to rain. Generally, Major League Baseball teams will continue play in light to moderate rain but will suspend play if it is raining heavily or if there is standing water on the field. Games can also be delayed or canceled for other forms of inclement weather, or if the field is found to be unfit for play.
I thought it rained a lot in Lexington, but boy was I wrong! It rains ALL the time here in New York. Sometimes all day, sometimes just for a few minutes. Either way it's really cramping my style. I thought I might as well embrace it. So I put on my brightest pants and took to the streets.
If a game is rained out before play begins, a make-up game is rescheduled for a later date. If a game is called after play begins but before 4½ innings have been completed (if the home team is ahead) or five innings have been completed (if the visitors are ahead or the game is tied), the game is not an official game. The umpire declares "No Game," the game is played in its entirety at a later date, and statistics compiled during the game are not counted. Games that are stopped after they become official games count in the standings (unless the game is tied, in which case it is replayed from the beginning), and statistics compiled during the game are counted.
