What are the save situations?

Answer 1

In order to record a save under Baseball rules, the following must happen: The pitcher must be the last to appear in a game won by his team. The pitcher is not the winning pitcher. The pitcher enters the game with a lead of no more than three runs, and records at least one out. He comes in with the potential tying run on base, at bat or on deck. A pitcher can also record a save by recording at least three effective innings to close out a game, at the discretion of the official scorer. Consequently, a blown save is when a pitcher enters a game in any of these situations and allows either the tying or go-ahead run to score.
