Definition: Bush league is a slang term used to describe behavior, plays, or conditions that are unprofessional, amateurish, or “cheap.” It originally referred to the “bush leagues,” which were small-town, low-level minor league teams that didn’t have the money or talent of the Major Leagues.

Definition: The diamond is the name given to the square-shaped area of the playing field that connects the four bases: home plate, first base, second base, and third base. While the entire stadium is often called a baseball field or a ballpark, the “diamond” specifically refers to the infield where the most intense action takes

Definition: A can of corn is a slang term for a very high, easy fly ball that a fielder can catch without much effort. It is the kind of play where the outfielder can just stand still, look up, and wait for the ball to fall right into their glove. It is considered the easiest

Definition: A changeup is a type of pitch designed to look exactly like a fastball when the pitcher throws it, but it actually travels much slower. The goal is to mess with the hitter’s timing. Because the pitcher uses the same arm speed and body motion as they do for their fastest pitch, the batter

Definition: A fielder’s choice is a play where a fielder catches a hit ball and chooses to try and get a different runner out instead of the batter. Because the fielder focused on another runner, the batter is able to reach first base safely. Even though the batter is “safe,” they are not credited with

Definition: A fly ball is a ball hit high into the air, usually toward the outfield. Unlike a ground ball that rolls on the dirt, a fly ball travels in a long arc, giving the fielders time to run underneath it to try and catch it before it touches the ground. If a fielder catches

Definition: A grand slam is a home run hit when all three bases are occupied by runners (the “bases are loaded”). Because the batter and the three runners on base all score, a grand slam results in four runs, which is the maximum number of points possible on a single play in baseball. A grand

Definition: A ground ball (or “grounder”) is a ball hit by the batter that bounces or rolls along the grass or dirt of the infield. Unlike a fly ball that travels through the air, a ground ball requires fielders to stay low and use their gloves to scoop the ball up from the ground. A

Definition: A ground rule double occurs when a fair batted ball bounces on the ground and then hops over or through the outfield fence. When this happens, the play is immediately dead, and the batter is automatically awarded second base while all runners on base move forward two bases from where they started. The rule

Definition: Loading the bases (or “bases loaded”) occurs when there are base runners on first, second, and third base at the same time. This is a high-pressure situation because any subsequent walk, hit, or hit-by-pitch will automatically result in at least one run scoring. Example: After three straight walks, the pitcher found himself with the

Definition: The manager is the person in charge of the team’s strategy and on-field decisions. They decide the starting lineup, choose when to switch pitchers, and are usually the ones who come onto the field to discuss rules or argue a call with the umpires. Example: The manager walked out to the mound to tell

Definition: The Mendoza Line is an informal term used to describe a batting average of .200. It is considered the threshold for “poor” hitting, and any player batting below this line is struggling to stay productive at a professional level. Example: The shortstop was worried about his spot on the team because his hitting had

Definition: A no-hitter is a rare and impressive game where a pitcher (or a combination of pitchers) prevents the opposing team from getting a single hit. While the other team might still reach base through walks, errors, or being hit by a pitch, they never once safely put the ball in play to reach a

Definition: On-deck refers to the player who is next in line to bat after the current hitter. This player stands in a designated circular area called the “on-deck circle” to warm up, practice their swing, and timing. Example: While the star player was at the plate, the next hitter was on-deck, stretching and watching the

Home plate is the five-sided white rubber slab where a batter stands to hit and where a runner must touch to score a run. It is the starting point and the final destination for every player circling the bases.Example: The catcher blocked the path, but the runner slid underneath him to touch home plate just

Definition: A perfect game is a rare masterpiece where a pitcher (or multiple pitchers) completes at least nine innings without a single player from the opposing team reaching base. This means no hits, no walks, no hit batsmen, and no errors—exactly 27 batters face the pitcher, and all 27 are put out. A perfect game

Definition: A pickoff is a quick throw from the pitcher (or catcher) to a fielder at a base in an attempt to catch a runner who has wandered too far away. If the fielder tags the runner before they can touch the base, the runner is out. A pickoff is a defensive move used to

Once a pinch hitter is used, the original player is removed from the game and cannot return. Managers usually use a pinch hitter for strategic reasons, such as putting

For a right-handed hitter, this means hitting the ball toward the left side of the field; for a left-handed hitter, it means hitting toward the right side. Example: The defense shifted all

Definition: A relief pitcher is a pitcher who enters the game after the starting pitcher is taken out. Their job is to “relieve” the starter and prevent the opposing team from scoring for the remainder of the game.
