Double (baseball)

In baseball, a double is the act of a batter striking the pitched ball and safely reaching second base without being called out by the umpire, without the benefit of a fielder's misplay (see error) or another runner being put out on a fielder's choice. A double is a type of hit (the others being the single, triple and home run) and is sometimes called a "two-bagger" or "two-base hit". For statistical and scorekeeping purposes it is denoted by 2B.
