Baseball

Baseball is a team sport that originated on Earth in the 19th century and gained world-wide popularity during the 20th Century. During this time professional leagues organized around the sport on several continents. The game continued to be played in the 21st century but it's popularity began to decline until 2042, when the final World Series was played and the professional stage of the game came to a close. Even so, the lexicon of the game endured and even in the 24th century the names and achievements of many of its greatest players were still known.

Benjamin Sisko is a noteable baseball fan, just like Kasidy Yates, as well as her brother on Cestus III, one of the few locations where the sport is still practiced in the 24th century.

Then Commander Sisko used the game of baseball to help the Prophets to understand linear time when he first encountered them. He explained that the reason the game was worthwhile was that corporeal beings like humans didn't know what the outcome would be. "Every time you throw this ball a hundred different things can happen in the game."

Sisko also kept a baseball on his desk in his office aboard Deep Space 9 and encouraged an interest in the game among his senior staff, including accepting a challenge to a game by the crew of the USS T'Kumbra in 2375.
