In the sports of baseball and softball, a batted ball is a pitch that has been contacted by the batter's bat. Batted balls are either fair or foul, and can be characterized as a fly ball, pop-up, line drive, or ground ball. In baseball, a foul ball counts as a strike against the batter, unless there are already two strikes on the batter, with special rules applying to foul tips and foul bunts. Fly balls are those hit in an arcing manner, with pop-ups being a subset of foul balls that do not travel far. Line drives are batted balls hit on a straight line trajectory, while ground balls are hit at a low trajectory, contact the ground shortly after being hit, and then either roll or bounce. Batted balls, especially line drives, can present a hazard to players, umpires, and spectators, as people have been seriously injured or killed after being struck by battle balls. Fair or foul On the playing field, two straight lines (each known as a foul line) are drawn from the corner of home plate; one past first base and one past third base. The foul lines extend all the way to the outer limit of the outfield, typically a wall or fence, and perpendicularly up the wall or fence. The entire area between foul lines, including the foul lines themselves, is considered fair territory; anything not in fair territory is considered foul territory. In general, batted balls are judged by where they land (first contact the ground) or are first touched by a player. That is, a batted ball landing in fair territory or first touched by a player in fair territory is fair, while a batted ball landing in foul territory or first touched by a player in foul territory is foul. However, batted balls in the infield (not yet at or beyond first base or third base) are judged on either where they are first touched by a player or where they come to rest. For example, if a batted ball in the infield first lands in foul territory but then rolls into fair territory and is touched there or comes to rest there, it is fair. Likewise, if a batted ball in the infield first lands in fair territory but then rolls into foul territory and is touched there or comes to rest there, it is foul. That a batted ball
