The World Series in Major League Baseball, is when the best team from the American League (the winner of the American League Championship Series) and the best team from the National League (the winner of the National League Championship Series) keep playing games of baseball until one of the two teams wins four games total. The winners of the most recent World Series in 2017 were the Houston Astros. They defeated the Los Angeles Dodgers four games to three.
The New York Yankees have 27 World Series championships, the most of any team. The Cleveland Indians currently hold the longest active drought, having last won the Series before expansion teams were formed. Recently, the three longest championship droughts were ended by the Boston Red Sox, Chicago White Sox, and the Chicago Cubs.
