Before the 2010 ALCS, the Rangers, Mariners, and Expos/Senators franchises were the 3 teams to never make it to the World Series. You can cross the Rangers off that list.
Previous Rangers postseason history was ’96, ’98, and the ’99 seasons. All three ALDS series were vs. the Yankees, and they only managed one win in 10 games against them. Eleven Years later the Rangers faced the Yankees again, this time in the ALCS instead. The Rangers dominated, winning the series 4-2.
