The World Series is the annual championship series of Major League Baseball (MLB), played between the American League and National League champions since 1903. The winner of the World Series championship is determined through a best-of-seven playoff and awarded the Commissioner's Trophy. As the series is played in October, Major League Baseball also refers to it as the "Fall Classic". The most recent World Series was won by the St. Louis Cardinals, who defeated the Texas Rangers in 7 games in 2011.

The New York Yankees of the American League have played in 40 World Series and won 27, and the Oakland/Philadelphia Athletics have played in 14 and won 9. In the National League, the St. Louis Cardinals have played in 18 and won 11, while the San Francisco/New York Giants and Los Angeles/Brooklyn Dodgers have both appeared in 18 and won 6.

Until the formation of the American Association in 1882 as a second major league, the National Association of Professional Base Ball Players (1871–75) and then the National League (founded 1876) represented the top level of organized baseball in the United States. All championships went to whoever had the best record at the end of the season, without a postseason series being played. Starting in 1884 and going through 1890, the National League and the American Association faced each other in a series of games at the end of the season to determine an overall champion. These matchups were disorganized in comparison to the modern Series: games played ranged from as few as three in 1884 (Providence defeated New York 3 games to zero), to a high of 15 in 1887 (Detroit beat St. Louis 10 games to 5), and both the 1885 and 1890 Series ended in ties, each team having won three games with one tie game.

Scott David Brosius (born August 15, 1966 in Hillsboro, Oregon) is a retired American Major League Baseball third baseman for the Oakland Athletics (1991–1997) and the New York Yankees (1998–2001). Brosius is currently the head baseball coach at Linfield College, his alma mater.

Brosius grew up in Milwaukie, Oregon, where he attended Rex Putnam High School before going to Linfield College. He was drafted by the Oakland Athletics in the 20th round of the 1987 amateur draft and signed on June 9, 1987. He became one of the limited number of players to hit a home run in his first major league game, on August 7, 1991. Brosius was the A's starting third baseman through the mid-1990s, although he played almost 300 games in his Oakland career at other positions, primarily in the outfield. In 1996, he batted .304 with 22 home runs, his best year with Oakland; however, his performance declined in 1997 when he became the last player to finish last in the majors, of those who qualified for the batting title, in batting average, on-base percentage, and slugging average. He was traded to the Yankees after the season for Kenny Rogers, who had struggled mightily in New York. In his first year in the Bronx, he batted .300 with 19 home runs and 98 RBIs.
