Systems and methods for securing bases, home plates, pitcher's rubbers, and double bases to synthetic turf

A method for releasably restraining a base, a home plate, a double base, or a pitcher's rubber on an upper surface of a synthetic turf field, the method comprising:

• removing a cover plug having synthetic turf from a frame assembly fixedly attached to a support structure under the synthetic turf field, the frame assembly having a peripheral wall and a bottom defining a cavity and at least one vertical member accessible via the cavity, the frame assembly having a first flexible seal extending above an upper opening of the peripheral wall of the frame assembly;
• positioning at least one downwardly-depending stanchion of the base, the home plate, the double base, or the pitcher's rubber over the cavity in the frame assembly;
• lowering the at least one downwardly-depending stanchion of the base, the home plate, the double base, or the pitcher's rubber to engage the at least one vertical member accessible via the cavity;
• disposing a bottom surface of the base, the home plate, the double base, or the pitcher's rubber over the cavity in the frame assembly and on the upper surface of the synthetic turf field around the peripheral wall of the frame assembly in the synthetic turf field;
• and wherein
• the frame assembly comprises a pair of half sections formed from a planar member with folded sides to provide a pair of vertical walls disposed at ninety degrees from each other, and a pair of horizontal walls to define the bottom of the frame assembly;
• a plurality of half section seal supports formed from a planar member with folded sides to provide a pair of vertical walls disposed at ninety degrees from each other, and a pair of offset vertical walls disposed at ninety degrees from each other, the offset vertical walls attachable to inner surfaces of the wall;
• and
• a plurality of half section turf ledges sections formed from a planar member with folded sides to provide a pair of vertical walls disposed at ninety degrees from each other, a pair of upper horizontal ledges disposed at ninety degrees from each other, and a pair of lower horizontal portions disposed at ninety degrees from each other.
