when can a foul ball be caught for an out
Foul ball In general, when a batted ball is ruled a foul ball, the ball is dead, all runners must return to their time-of-pitch base without liability to be put out, and the batter returns to home plate to continue his turn at bat. A strike is issued for the batter if he had fewer than two strikes. If the batter already has two strikes against him when he hits a foul ball, a strike is not issued unless the ball was bunted to become a foul ball, in which case a third strike is issued and a strikeout recorded for the batter and pitcher. A strike is, however, recorded for the pitcher for every foul ball the batter hits, regardless of the count. If any member of the fielding team catches a foul ball before it touches the ground or lands outside the field perimeter, the batter is out. However, the caught ball is in play and base runners may attempt to advance.
Rules of snooker A free ball is a player-nominated substitute for the ball on when the player is snookered by a foul.[1] This is because the snooker in this case is produced by a foul and thus not considered legitimate. As such the player is allowed to pick any ball as a free ball, which is then effectively treated as the ball on, thereby voiding the illegitimate snooker. Once the free ball shot is taken legally, the game continues normally (although, if the offending player was asked to play the shot again, then the free ball is void, having to resolve the self-inflicted snooker).
