In the sport of baseball, small ball is an informal term for an offensive strategy in which the batting team emphasizes placing runners on base and then advancing them into scoring position for a run in a deliberate, methodical way. This strategy places a high value on individual runs and attempts to score them without requiring extra base hits, or sometimes without base hits at all, instead using bases on balls, stolen bases, sacrifice bunt or sacrifice fly balls, the hit-and-run play, and aggressive baserunning with such plays as the contact play. A commonly used term for a run produced playing small ball is a "manufactured run". This style of play is more often found in National League game situations than in the American League due in large part to the absence of the designated hitter in the National League.
Teams may incorporate a small-ball strategy for a variety of reasons, including:
Most commonly, managers will switch to small-ball tactics while a game is in progress, doing so upon the convergence of a variety of factors including having appropriate hitters coming up next in the batting order and, often, having fast runners already on base. A team could also start the game with the intention of playing small ball but then change from this strategy at some point during a game, depending on circumstances, such as when the opposing pitcher is struggling or has left the game or when the team is ahead or behind by several runs.
Small ball is a contrast to a style sometimes called the "big inning", where batters focus more on drawing walks or getting extra-base hits and home runs. This may produce many innings with little but strikeouts and flyouts, but occasionally innings with several runs. By playing small ball, the team trades the longer odds of a big inning for the increased chances of scoring a single run. Specifically, small ball often requires the trading of an out to advance a runner and therefore usually reduces the number of batting opportunities that a team will have in a given inning.
