Serie del Rey
The Serie del Rey is the annual championship series of the Mexican Baseball League, held since 1970. The champions from the league's two divisions, the North and South Zones, compete in a best-of-seven series, with the winner being awarded the Copa de Zaachila. Originally known simply as the Serie Final, the championship series was renamed in 2012, in reference to baseball being called the king of sports.
Before 1970, the league champion was the winner of the most games in a round robin tournament.
The Diablos Rojos del México are the most successful team in LMB history, having won 18 championships in total and 15 of those in the Serie del Rey era. Diablos have also played in 24 championship series since 1970, the most of any team. They are followed by the Tigres de Quintana Roo, who have played in 13 series since 1970 and won 8, and the Sultanes de Monterrey who have played in 12 and won 5.
