Balk: Any pitching motion that is against the baseball rules, resulting in any runners on base advancing one base.
Battery: The battery includes two baseball players, the pitcher and the catcher. A pitcher and catcher from the same team are known as “battery mates.”

Closer: A relief pitcher (closing pitcher) who is consistently used to “close” or finish a game by getting the final outs.
Curveball: A pitch that curves or breaks from a straight or expected flight path toward home plate.
Dropped third strike: A dropped third strike occurs when the catcher fails to cleanly catch a pitch which is a third strike (either because the batter swings and misses it or because the umpire calls it). The pitch is considered not cleanly caught if the ball touches the dirt before being caught, or if the ball is dropped immediately after being caught. On a dropped third strike, the strike is called (and a pitcher gets credited with a strike-out), but the umpire indicates verbally that the ball was not caught and does not call the batter out. If first base is not occupied at the time (or, with two outs, even with first base occupied), the batter can then attempt to reach first base prior to being tagged or thrown out. Given this rule, it is possible for a pitcher to record more than three strike-outs in an inning.
Fastball: The most commonly thrown pitch in baseball, it is a pitch that is meant to be thrown very fast. There are different variations of fastballs.
Framing a pitch: Refers to the positioning and or movement of the catcher’s mitt and body when he catches a pitch in the attempt to make the pitch appear as a strike to the umpire. Typically done on pitches that are slightly outside the strike zone and may be questionable for the umpire to call a strike.

Hanger: A poorly placed off-speed pitch that seems to just hang in the air, usually right down the middle of the strike zone, that can be easily hit by the batter.
Heat(er): Another term for a fastball. “This pitcher is throwing heat.” “That pitch was a heater.”
Intentional walk: When the defending team elects to walk a batter on purpose, putting him on first base instead of letting him try to hit.
Live on the corners: A pitcher is said to “live on the corners” when they are consistently making pitches on the outside or inside corners of home plate.
Meatball: When a pitcher is throwing pitches that are extremely easy to hit. “This pitcher is throwing meatballs!”
Middle reliever: A relief pitcher who is brought in typically during the middle-innings (4, 5, and 6).
No-hitter: A game in which one team does not get any hits; a rare feat for a pitcher, especially at the major league level. Also called a “no-no.”
Off-speed pitch: A pitch that is significantly slower than a given pitcher’s fastball. Typically, a curveball or changeup of some variation.
On the bump: This phrase is used when talking about a pitcher on the pitcher’s mound. “On the bump tonight is [insert pitcher’s name here].”

Save situation: Generally, a save situation is when a pitcher enters the game in the seventh inning or later with a lead of three runs or fewer. This is typically what the closer (closing pitcher) is brought into the game for. Also called a save opportunity.
Set-up pitcher: A relief pitcher who is consistently used immediately before the closer.
Slurve: A pitch that is a cross between a slider and a curveball.
Southpaw: A left-hand thrower; typically, used to describe a pitcher.
Stretch: The stretch is a simpler, more compact pitching position. The stretch is most commonly used when there are base runners on first or second base. Since this pitching motion takes less time, it gives the runners less time to steal bases. Some pitchers like to use the stretch all the time regardless of the base runners.
Submarine: A pitcher who throws with a severe sidearm motion, making the pitch appear to come from below the waist or even right off the ground, is said to throw “submarine.”
Take the hill: When a pitcher steps on the mound they are said to “take the hill.”
Throw ’em a chair: Most commonly used when cheering on a pitcher to strike out a batter, due to the batter going back to the dugout to sit down after striking out.
Uncle Charlie: A term sometimes used for a curveball.
Walk: When the pitcher throws four balls to a batter before throwing three strikes, the batter gets to go to first base automatically.
