Baseball jargon

1-1 (i.e., "one and one"), also, 0-1, 1-0, 1-2, 2-1, 2-2, 3-2 - instances of the "pitch count," the number of balls and strikes currently totaled for the batter.

bottom of the inning - the second half of an inning, during which the home team bats.

chase after - swing at a pitch well outside of the strike zone.

check the runner - when the pitcher looks in the direction of a runner on base, and thereby causes him to not take as large of a lead as he would otherwise have taken.

down the line - on the field near the foul lines, often used to describe the location of batted balls.

down the middle - over the middle portion of home plate, used to describe the location of pitches.

drop off the table - when a pitched ball (e.g., a curveball) breaks extremely sharply.

high and tight - high, or above the strike zone, and close to the batter, used to describe the location of pitches.

hot corner - the third base fielding position, so called because many batted balls arrive very quickly to the position.

in the hole - on the infield at a location nearly exactly between fielders, used to describe the location of batted balls.

K - strikeout. A backwards K is sometimes used to denote a strikeout looking and forwards to indicate a strikeout swinging.

lead off (batting order) - the player who is first in the batting order for a given team.

lead off (base running) - when a base runner steps off of the base in order to reduce the distance to the next base, before a pitch is thrown.

load the bases - when base runners are caused to exist on all bases (first, second, and third base).

outside corner - over the edge of home plate away from the batter, used to describe the location of pitches.

shoestring catch - when a fielder, usually an outfielder, catches a ball just before it hits the ground, and remains running while doing so.

slice foul - when a fly ball or line drive starts out over fair territory, then curves into foul territory due to aerodynamic force caused by spinning of the ball, imparted by the bat.

Texas Leaguer - a weakly hit fly ball that drops in for a single.

top of the inning - the first half of an inning, during which the visiting team bats.

up the middle - on the field very close to second base, used to describe the location of batted balls.
