Bat-and-ball games

The teams alternate between "batting" (offensive) role, sometimes called "in at bat" or simply in, and "fielding" (defensive role), also called "out in the field" or out. Only the batting team may score, but teams have equal opportunities in both roles. The game is counted rather than timed. The action starts when a player on the fielding team puts the ball in play with a delivery whose restriction depends on the game. A player on the batting team attempts to strike the delivered ball, commonly with a "bat", which is a club governed by the rules of the game. After striking the ball, the batter may become a runner trying to reach a safe haven or "base". While in contact with a base, the runner is safe from the fielding team and in a position to score runs. Leaving a safe haven places the runner in danger of being put out. The teams switch roles when the fielding team puts the batting team out, which varies by game.
