Beep baseball

Beep baseball is played on a grass field with six fielders (generally a first-baseman, third-baseman, shortstop, left fielder, right fielder, and center fielder, although two-four defensive sets are not unheard-of) and one or two "spotters" from one team, and the pitcher, catcher, and batter from the other team. Fielders and batter are blindfolded. There is also a D.H. and D.F. (designated fielder). They must be legally blind, in most cases. However, the NBBA has a rule that, if a team cannot field the minimum six batters required to fill its lineup card, it may opt to allow up to two sighted volunteers to blindfold themselves and play as the players with visual impairments do. Catcher, pitcher, and spotters do not wear blindfolds and are usually sighted, although there have been a few who are partially blind. The ball beeps and is a modified, oversized softball. The bases are blue, nearly 5 ft (1.5 m) tall, and have mostly foam interior with electronics that cause it to buzz steadily when a switch is thrown. They are each placed 100 ft (30 m) from homeplate and are in the equivalent positions to first and third bases in regular baseball.

When the batter hits the ball, a base operator turns on one of the two bases (first or third) for the batter to run to. If the batter touches the base before a fielder can pick up the ball, the offensive team scores a run. It takes four strikes for a batter to be out. If the ball goes beyond the two base lines or doesn't travel at least 40 ft (12 m), it is foul and counted as a strike, unless it is the potential fourth strike, in which case the count holds and the batter just swings again. If a batted ball travels at least 170 ft (52 m) in the air over fair territory before settling, it is, upon declaration of the umpire, a home run. If the ball ceases to beep, or if it hits the pitcher, and becomes a "dead ball," the count is reset and the batter swings again. A dead ball must not be touched. If it is, it is said to be back in play and the out must be recorded.

The spotter or spotters call out a number to signify which part of the field a ball is traveling toward. Generally, the middle of the outfield is labeled 6, and either side, left and right, is numbered from 1 to 5 in a mirroring pattern. The spotter must not say anything beyond the numbered region on the field, and two spotters cannot make a call on the same play. If either case occurs, the run scores. The fielders head toward that section and listen for where the ball is specifically, often diving to the ground to get it. When a fielder picks up the ball before the batter reaches the base, the batter is out. In the rare event that a fielder catches the ball in the air before it touches the ground or other items, the side is automatically retired and the next half-inning commences. The spotter must also watch to ensure that nobody collides.

Beep baseball generally has six innings. The extra innings rules used in Major League Baseball generally apply to beep baseball. If one team is up by twelve or more runs, the other team has the opportunity to have short innings in which the losing team bats every inning and the winning team fields. This is known as the twelve-run rule; when it occurs, one team is said to "twelve-run" another. If the other team makes up the difference, the team that had been winning gets back all their missed at-bats.

There are no age- or gender-based restrictions in beep baseball; people as old as 70 and as young as 12 have played.
