Racquetball
Racquetball was a game for two or four players, played in a four-walled court, using short-handled rackets and a small rubber ball. 

Julian Bashir was the  of the Starfleet Medical Academy racquetball team in 2368. His team won the Sector Championships in his final year. He played against a Vulcan opponent in his final match, however, he found his greatest opponents were the ones with no formal training. At another tournament, he picked up a 5,000-year-old battle warm-up exercise from a top player. According to legend, the warm-up makes the heart a friend to the hand. ()

In 2367, Captain Jean-Luc Picard introduced Jono to the game as a way of relieving stress. ()

In 2370, Miles O'Brien built a racquetball court aboard Deep Space 9. Not long after, Quark promoted a "charity match" between O'Brien and Bashir, with an undisclosed amount of the proceeds from wagering going to the Bajoran War Orphans Fund. The match began but was never finished due to disturbances in the Laws of Probability aboard the station. ()

After two months of Keiko O'Brien's absence in early 2371, Miles O'Brien and Julian Bashir had played 70 games of racquetball. By late that year, they were up to 106 games, at which point they changed over to darts. ()

Benjamin Sisko and Jake had scheduled a racquetball game in 2371, but it was delayed due to the activation of Dukat's counter-insurgency program. ()

O'Brien recalled playing one of many racquetball matches with Bashir as he was leaving Deep Space 9 after the end of the Dominion War. ()
