baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called "runs".

inning
thumb|A baseball scoreboard
In baseball, softball, and similar games, an inning is the basic unit of play, consisting of two halves or frames, the "top" (first half) and the "bottom" (second half). In each half, one team bats until three outs are made, with the other team playing defense. A full baseball game is typically scheduled for nine innings, while softball games consist of seven innings, although this may be shortened due to weather, or extended if the score is tied at the end of the scheduled innings. The use of the term inning in baseball and softball contrasts with cricket and round

bullpen
In baseball, the bullpen (or simply the pen) is the area where relief pitchers warm up before entering a game. A team's roster of relief pitchers is also metonymically referred to as "the bullpen". These pitchers usually wait in the bullpen if they have not yet played in a game, rather than in the dugout with the rest of the team. The starting pitcher also makes his final pregame warm-up throws in the bullpen. Managers can call coaches in the bullpen on an in-house telephone from the dugout to tell a certain pitcher to begin their warm-up tosses. Relief pitchers are often assisted in their war

In baseball, a rundown, informally known as a pickle, the hotbox, or goose chase is a situation that occurs when the baserunner is stranded between two bases, also known as '''no-man's land''', and is in jeopardy of being tagged out. When the baserunner attempts to advance to the next base, he is cut off by the defensive player who has a live ball, and attempts to return to his previous base before being tagged out. As he is doing this, the defender thr

On-deck

In baseball, on-deck refers to being next in line to bat. In a professional game, the batter who is on deck traditionally waits in a location in the foul territory called the on-deck circle.

Being on-deck only guarantees the batter will get a chance to bat in the inning if there are fewer than two outs, and the number of outs plus the number of baserunners (including the one at bat) adds up to fewer than three, because a d

In baseball, a pickoff is an act by a pitcher or catcher, throwing a live ball to a fielder so that the fielder can tag out a baserunner who is either leading off or about to begin stealing the next base.

A pickoff attempt occurs when this throw is made in an attempt to make such an out or, more commonly, to "keep the runner close" by making it clear that the pitcher is aware and concerned with the runner's actions. A catcher may also attempt to throw runners out who likewise "stray too far" from their bases afte
