 Behind home is the catcher's box, where the catcher and the home plate umpire stand.Next to first and third base are two coaches' boxes, where the first and third base coaches guide the baserunners, generally with gestures or shouts.As the baserunner faces away from the outfield when running from second base to third, they cannot see where the ball is, and must look to the third base coach on whether to run, stop, or slide.
