Categoría Primera B, commonly referred to as Torneo BetPlay Dimayor due to sponsorship by online betting company BetPlay,[1] is the second-division football league in Colombia.[2] DIMAYOR has applied a new format from 2015 onwards because of the expansion to 20 teams in the Primera A tournament.The league will no longer have Apertura and Finalización seasons but rather a yearlong tournament with home and away games.The second is a two-groups phase with the 8 top teams from the season who play each other to determine the winners of each group.The winners of the two groups are both promoted to the Primera A and play the final in home and away games to determine the champion of the season.
