Pennant
A pennant is usually a narrow tapering flag most commonly flown by ships at sea.
A commissioning pennant is the traditional sign of a warship, and is flown from the masthead while the ship is in commission.
A broad pennant in the Royal Navy is a swallow-tailed tapering flag flown from the masthead of a ship to indicate the presence of a commodore. It is so called because its dimensions are roughly 2:3.
A church pennant in European navies is flown during church services. In the United States Navy, a pennant is also flown over the national colors during religious services.
Unlike the triangular pennant, most national and departmental flags are rectangular; the national flag of Nepal and the state flag of Ohio in the U.S. are the only notable modern flags to be a variation of the standard pennant.

In baseball, a pennant is a commemorative flag flown by the champion of a league, and has come to refer to the league championship itself. The Pennant race is the last few weeks of the season, when lower-ranked teams are steadily eliminated from contention, leaving the three divisional champions and one wild card team from each league at the beginning of the playoffs.
