Spectator seating offering a very poor view of the playing field. Named in honor of longtime Milwaukee Brewers announcer Bob Uecker, in reference to one of his TV ads in which he is removed from the box seats and learns that his ticket is actually for a seat in the back row of the right field upper deck.
A grand slam by a member of the home team when they are exactly three runs behind in the bottom of the final inning, thus overcoming a 3-run deficit and winning the game with one swing. See also walk-off home run.
When a fielder single-handedly executes a play which is more often completed by multiple fielders. For example, with a runner on first base, a ground ball is hit to the shortstop who then steps on second base, completing a force out. Unassisted double plays are rare, and unassisted triple plays are extremely rare.
If a base runner successfully advances to the next base while the pitcher is delivering the ball to home plate but the catcher does not attempt to throw him out, then the steal may be scored as an uncontested or undefended steal. In the game's statistics, the runner would not be credited with a stolen base. Also called defensive indifference. See also stolen base, fielder's choice.
A pitch to the upper part of the strike zone. "When Miller throws his fastball up in the zone, opponents are hitting .079 (6-for-76) and have missed on 36 percent of swings (league average is .232). When his fastball is down or in the middle of the strike zone, opponents hit .270 with a miss rate of 15 percent."
The area near an imaginary line from home plate through the pitcher's mound and second base into center field. General managers typically build teams "up the middle", i.e. strength at catcher, second base, shortstop, and center field.
