As of , all thirty MLB teams have reached the LCS at least once. The Houston Astros and Milwaukee Brewers are the only teams to have played in both the ALCS and NLCS. Five teams have never lost an LCS: the Colorado Rockies (won in 2007), the San Diego Padres (won in 1984 and 1998), the Miami Marlins (won as the Florida Marlins in 1997 and 2003), the Tampa Bay Rays (won in 2008 and 2020), and the Texas Rangers (won in 2010 and 2011). Out of this group, only the Marlins have won a World Series title; they did it both times they reached the NLCS.
