Embodiments of the present invention relate to apparatuses and methods for releasably securing a structural member of a movable goal, such as a soccer goal, to a surface, such as the ground. For example, in one embodiment, an apparatus is provided comprising: (1) an enclosure structured to be placed at least substantially below the surface, the enclosure defining a cavity; (2) a goal engaging member movable relative to the surface and structured to engage the structural member of the movable goal; and (3) a tightening mechanism mounted within the enclosure and operatively connected to the goal engaging member, the tightening mechanism being structured to urge the goal engaging member toward the tightening mechanism so that the goal engaging member releasably secures a portion of the structural member of the movable goal.
