A ball is considered fair if it touches a player or an umpire while in fair territory. It is determined by the ball’s position when it is touched. A foul ball occurs when a batted ball crosses foul territory and collides with a player or umpire.
In baseball, there is no set limit to how many foul balls a batter can hit. Even though a foul ball is considered a strike, a foul ball will not increase the number of strikes when the batter already has two strikes in the count.
(1) A fly ball or line drive, which passes over or inside first or third base in flight and curves to foul ground beyond such base, is not a fair hit; but a hit which goes over or through the fence is a fair hit if it is over fair ground when it leaves the field.
Outfield Foul Balls
In the outfield a ball is determined to be foul by its relationship to the line when it first touches the ground or is touched by a player. So if a ball hit in the outfield lands in fair territory and then rolls foul, it is a fair ball. This is different than with the infield.
Batted balls that first contact the field between home plate and first or third base are considered foul if they don’t subsequently bounce over or directly contact either base, otherwise pass either base while in fair territory, or ultimately settle at some point in fair territory between home plate and either base.
If a batted ball hits the plate first it’s a foul ball.
Approved Ruling: Home plate, first, second, and third base are all completely within fair territory. The foul lines are also within fair territory. In order to rule the ball foul, it must have come to rest in foul territory or be touched in foul territory.
A foul ball can count as a Strike 1 and a Strike 2, but never a Strike 3. A foul ball pop-up/fly ball is treated the same as any ball hit inside the lines. This means if a runner is on base, he can tag up and risk running to the next bag. This includes scoring, if it is an option.
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.
A foul tip is always a strike, regardless of the existing ball-and-strike count. A player with two strikes against him is automatically struck out. A player with fewer than two strikes against him is not out.
You cannot steal a base on a “dead” or foul ball. Overthrown or passed balls may be stolen on, as long as the ball is still considered to be “live” The base ahead of you must be unoccupied (unless the runner ahead of you also attempts to steal the base in front of them; this is known as a double steal)
Definition. A foul tip is a batted ball that goes sharply and directly to the catcher’s hand or glove and is legally caught. A foul tip is considered equivalent to a ball in which the batter swings and misses, in that the baserunners are able to advance at their own risk (without needing to tag up).
If a batter swings and misses a ball and in the process unintentionally hits this catcher on his backswing, it shall be called a strike, and not batter interference. Batter non-interference applies as long as the batter’s feet remain in the batter’s box. The ball is called dead by the umpire and the play is halted.
A fielder may go into foul territory to back up an appeal after the ball has been put into play. d. All personnel except the nine defensive players on the field must remain in the dugout or bullpen (see 5-2-c PENALTY).
If a batted ball contacts the foul pole while in the air, it is considered a home run. If a batted ball bounces in the outfield then hits the foul pole, it is considered a ground-rule double and the umpire awards bases accordingly. It does not matter what happens to the ball once it ricochets off the foul pole.
In basketball, a foul is an infraction of the rules more serious than a violation. Most fouls occur as a result of illegal personal contact with an opponent and/or unsportsmanlike behavior.
In every case of spectator interference with a batted or thrown ball, the ball shall be declared dead and the baserunners can be placed where the umpire determines they would have been without the interference.
If the batter unintentionally throws his bat and it interferes with the fielders, interference is called and the batter is out. If the batter throws his bat intentionally, the batter will be ejected for unsportsmanlike conduct.
If a batter hits a pitched ball with any part of his foot or knee outside of the batter’s box, including home plate, then the batter is out.
Definition of tag
For a legitimate tag, the fielder must have the ball held securely in either the hand or the glove. Nowhere else.
A fly ball hit in foul territory is in play and can be caught for an out; baserunners can advance as on any other fly ball out. If it drops to the ground, it is simply a foul ball, and runners cannot advance. A ground ball hit in foul territory is simply a foul ball, and cannot be played.
In all four cases the catch would be legal, as dictated by the best judgment of the umpire. The same restrictions apply to a foul ball descending into a stand. A catcher or fielder may not jump into a stand to catch such a ball, but reaching into the stand and making the play is permitted.
Multiple runners can tag up on the same play, as long as they are advancing to a base that has no current runner. Only one runner can occupy a base at any given time.
A ball that is not caught by the catcher is not (and cannot be) a foul tip. A foul tip is always a strike; and, unlike a foul ball, a foul tip can result in strike three. A foul tip is a live ball. Runners can advance (steal) at their peril.
If an outfielder catches the home run with one foot on or over the playing surface and maintains possession of the baseball then the batter is called out. However, if no part of the player is on or over the playing surface then the play is ruled a home run.
