What is baseball?
Baseball is a nine-a-side bat-and-ball game played over nine innings — pitchers against hitters, runs scored around four bases — the historic American team sport and the defining sport of the Caribbean basin and East Asia. Its professional summit is Major League Baseball; its international game runs under the WBSC.[1] [2]
How does baseball work?
There is no clock: each team bats until three outs, nine innings decide it, and a 162-game MLB season rewards depth like no other sport. The professional pyramid is deep and formalized — the Minor Leagues' four classes feed MLB, winter leagues run across Latin America, and Japan's NPB and Korea's KBO are major leagues in their own right. Player movement is documented at every step: contracts, options, waivers and international signings.[1] [2]

What are baseball's origins?
Evolved from English bat-and-ball games and codified in 1840s New York (the Knickerbocker rules), professional by 1869 and organized into the National League in 1876. The sport spread with American trade and military presence — to Cuba and the Caribbean in the 1860s-70s, to Japan in the 1870s — which is why its greatest talent pools today ring the Caribbean and the Pacific.[1] [3]
Where is baseball popular?
The United States and Japan are its biggest markets, but per capita nowhere loves baseball like the Caribbean basin: the Dominican Republic supplies more MLB players than any country outside the U.S., with Venezuela close behind — over a quarter of major leaguers are born abroad, led by those two nations plus Cuba, Puerto Rico and Mexico. Venezuela's 2026 World Baseball Classic title, won in Miami, was a national event.[2] [4]
Who governs baseball?
The WBSC governs the international game — world rankings, World Cups, Olympic baseball — through nearly 200 national federations, USA Baseball among them. MLB governs the professional game in North America and, with the players' union, runs the World Baseball Classic; NPB, KBO and the winter leagues govern theirs, with the Caribbean confederation uniting the winter champions each February.[2] [5]
What are the most important competitions in baseball?
- The World Series — MLB's championship, the sport's biggest club stage since 1903.[2]
- The World Baseball Classic — the national-team championship with major leaguers, every three-to-four years.[4]
- The Olympic tournament — returning at LA28, with softball beside it.[5]
- The Caribbean Series — the winter-league champions of Latin America, each February since 1949.[6]
- Japan's NPB and the Japan Series, Korea's KBO, and the WBSC Premier12 between Classics.[5]
- The College World Series — Omaha's June institution.[7]
How is baseball awarded?
- MVP, Cy Young and Rookie of the Year awards — the BBWAA's honors — plus All-Star selections, Gold Gloves and Silver Sluggers.[2]
- National-team selection for the Classic, Olympics and WBSC events, with the WBSC World Rankings the official ladder of nations.[5]
- The MLB Draft and international signings — signing bonuses and draft position are public, graded credentials.[2]
- Winter-league honors — LIDOM and LVBP titles, Caribbean Series MVPs — the credentials of the Latin American game.[6]
- Statistical records — every professional career documented on Baseball Reference, minors included.[8]
What is the college role in baseball?
College baseball is a genuine second pathway beside the high-school draft and international signings: the College World Series has filled Omaha every June since 1950, the American Baseball Coaches Association names All-Americans, and NJCAA and NAIA programs — plus the wooden-bat summer leagues like the Cape Cod League — extend the ladder. Most American draftees now arrive through college programs.[7]
Which media cover baseball?
Baseball's press is the oldest in American sport — ESPN, The Athletic and MLB's own network lead coverage, with Baseball America the authority on prospects — while Baseball Reference is the sport's statistical record and the WBSC Rankings its official national-team database.[2] [8]
