A sports racquet attachment includes a shaped body for attachment to a portion of a racquet. The ball retrieval racquet attachment has a pick-up cup at an end of the ball retrieval racquet attachment and a butt cap opening at another end of the ball retrieval racquet attachment. The pick-up cap has at least one ball finger interior to the pick-up cup. The butt cap opening has at least one butt cap stopper interior to the butt cap.

Embodiments disclosed provide a solution to detect a rally in a sports game. One or more stroke actions or non-stroke actions are detected based on motion data detected by a sensor attached to a sports instrument of a user. Using a trained stroke classification model, each detected stroke action is classified into a plurality of classes. Additionally, a determination is made whether each detected non-stroke action is an intentional special user action. The determination whether a non-stroke action is an intentional special user action is made based on a customized set of definitions defining one or more special user actions. One or more rallies are then detected based on the classified stroke actions and intentional special user actions.

A snowball launching and batting apparatus comprising a barrel member, a handle member, and a knob feature, the handle member further comprising a primary cradle structure configured to accept, form, and store snow or snowballs. The apparatus further comprises a secondary cradle structure capable of coupling the primary cradle structure and configured to accept, form, and store snow or snowballs. The knob feature may further comprise a depression configured to form snowballs. The apparatus is further configured to have an extended and retracted state. A user inserts snow into the barrel and cradle structure to form a snowball and inserts it into the apparatus while in an extended state. Launching the snowballs from the apparatus may comprise swinging the apparatus or applying a force to the handle member to quickly move it from an extended state to a retracted state.

A removable paddle attachment assembly is provided. The attachment assembly may include a attachment bracket terminating at opposing saddles, a handle saddle for engaging a first portion of a watercraft paddle and an activity saddle for engaging an activity device, whereby the activity device is removably yet rigidly secured to the watercraft paddle so that the activity device may be employed for game-playing and/or exercise-training purposes, while not impairing the performance and functionality of the watercraft paddle. The attachment bracket provides at least one attachment strap cleat so that a attachment strap may be stretched from one lateral surface of the attachment bracket to an opposing lateral surface thereof, thereby securely sandwiching the first and a second portion of the watercraft paddle against the handle saddle.
