baseball

1. baseball (noun) — sense 1

Definition: A sport common in North America, the Caribbean, and East Asia, in which the objective is to strike a ball so that one of a nine-person team can run counter-clockwise among four bases, resulting in the scoring of a run. The team with the most runs after termination of play, usually nine innings, wins.

Example: It was not very wonderful that Catherine, who had nothing heroic about her, should prefer cricket, base-ball, riding on horseback, and running about the country at the age of fourteen, to books.

2. baseball (noun) — sense 2

Definition: The ball used to play the sport of baseball.

Example: The reason we have for so long been unaware that the universe evolves probabilistically is that for the relatively large, everyday objects we typically encounter -- baseballs, flowerpots, the Moon -- quantum mechanics shows that the probabilities become highly skewed, hugely favoring one outcome and effectively suppressing all others. […] With such a skewed probability, the quantum reasoning goes, we have long overlooked the tiny chance that the baseball can (and, on extraordinarily rare occasions, will) land somewhere completely different.

3. baseball (noun) — sense 3

Definition: A variant of poker in which cards with baseball-related values have special significance.
