Most pitchers are generally good athletes with competitive spirits. Their success is in direct proportion to the number of runs their team scores. High ERA's are most preferable. Playing defense is the most challenging aspect of beep ball. Not all teams use the same defensive placement of their players.
Most teams use the same numbering system to identify defensive positions.
Also, there are one or two sighted spotters positioned in the outfield, one on either side of the field. When a ball is hit, a spotter will instantly call out the number indicating the general direction the ball is traveling. The players coordinate their defensive moves according to the number that is called. The players can verbally communicate with each other and frequently do. But, if a spotter says more than the allowed number, the batter is awarded a run.
