COUNT ON THE BATTER
Given by the ump after each pitch to let everyone know how many balls and strikes have been called on the batter. The ump will hold up fingers on the left handoff the amount of balls and use the right hand to show the amount of strikes. When the count reaches 3 balls and 2 strikes a verbal "full or full count" is given.
FAIR BALL CALL
"Fair Ball" is given on balls that are in question of being fair or foul. Example; balls that are hit near the foul line. On a close call the ump will repeat the action multiple times so all players know the ball is live. Raised arm, point in the direction of fair territory. No verbal is given.
FOUL TIP CALL
A foul tip is a batted ball that goes sharply and directly to the catcher's bare hand or glove and is legally caught. A would tip is considered equivalent to a ball that a hitter swings and misses, in that baserunners are able to advance at their own risk (without needing to tag up). If the batter were to have a foul tip with already having two strikes, the foul tip is considered strike three and the batter is out.
In order to have the infield fly rule to be in play 1) there must be less than 2 outs 2) there must be runners on 1st and 2nd or the bases must be loaded 3) the fly ball cannot be bunted or aline drive 4) an infielder must to be able to catch the ball with ordinary effort. The umpire points at the sky and calls "infield fly".
The safe call is used when a runner has reached the base safely and is not out. Also used on close balls hit to fielders (no catch) and are not called "out". The umpire will extend both arms together in front and give a quick sweeping motion outward, roughly parallel to the ground, palms down. A verbal "safe" can also be used at the same time.
"strike" call is given on a called strike or on a swing and miss by the batter. The right arm is raised with a pointed finger in the direction of 1st base. On a swing and miss by the batter, no verbal is given just a hand sigh. On a called "strike" then a verbal and point will both be used.
