Racquetball

Racquetball is a human game, designed for 2 to 4 players, who play inside a walled-court with short-handed rackets and a rubber ball.

In the 2240s, Gary Mitchell was a keen player of racquetball and participated in many tournaments. Unfortunately, he lost interest in 2249 after losing in the singles tournament of the New York State championship. In the same year, James T. Kirk also participated in a tournament in Sioux City. (TOS - My Brother's Keeper novel: Republic)

Years later in 2287, Kirk played several games of racquetball with a diplomat who the USS Enterprise was transporting to a summit on Starbase 49. (TOS novel: In the Name of Honor)

In 2367, Captain Jean-Luc Picard played a racquetball game against Jeremiah Rossa, in an attempt to break through the boy's Talarian conditioning and embrace his human emotions. (TNG episode: "Suddenly Human")

In 2368, Julian Bashir was the captain of the Starfleet Medical Academy racquetball team. In his final game before graduation, he played against a Vulcan. (DS9 episode: "Rivals")

In 2370, Miles O'Brien constructed a racquetball court on Deep Space 9 so that he and any other racquetball players on the station would have a court to play on. Doctor Julian Bashir soon discovered this court, and the two men played racquetball quite frequently. The Ferengi Quark seized upon the opportunity to raise funds for the Bajoran War Orphans Fund, by promoting a number of matches between Bashir and O'Brien. (DS9 episode: "Rivals")
