The twist-inhibiting collar includes a first surface configured to engage with an ulnar edge of a first hand of a player, and a second surface configured to engage with a radial edge of a second hand of the player, the second surface opposite the first surface. The collar also includes an aperture passing through the first surface and the second surface and defined by an interface surface that is coupled to a sport implement held by the player. The twist-inhibiting collar includes an elastomeric material. The sport implement may be a bat having a handle, and the aperture may be sized to fit the handle. The sport implement may be a golf club having a grip, and the aperture may be sized to fit the grip.
