Ball base construction and anchor

An improved ball base comprising, in combination:

• a unitary rectangular base pad member divided into two sharply defined, equally sized square subsections, each subsection being the size of a regulation base with each subsection having visually distinct monochromatic color and a sharp, straightline boundary therebetween, one section being designated for the fielder and the other section being designated for the runner;
• a rod member for securing the base to the ground with the foul line coincident with the boundary, the rod member comprising an elongated bar impact-drivable into the ground;
• and
• a connection system for securing the rod member to the base paid member, and thereby for securing the boundary coincident with a foul line with the fielder's section in the field of play and the runner's section outside the field of play, the connection system comprising a lower plate affixed to the rod member, and a cooperative upper plate affixed to the approximate center of the base pad member's lower surface, the upper plate having side flanges paralleling the base pad member's longer sides and forming opposed grooves for tongue and groove insertion of the lower plate into the grooves parallel to the upper plate, the upper plate also having a stop flange depending from the upper plate transverse to the side flanges and positioned at an upper plate edge to limit sliding of the lower plate in the upper plate side flange grooves, whereby the rod member and lower plate may be driven into the ground and the base member may be removably attached to the ground by sliding the lower plate as a tongue into the grooves of the upper plate side flanges until the lower plate rests against the stop flange aligning the base with the first base foul line so that the sharp transition between each subsection's colors corresponds with the foul line and a base runner may run to a base subsection different from the subsection contacted by a baseman.
