The Rangers won 18 post-season games over the last two years but did not win the World Series in either year. In fact, they won more post-season games than 11 of the World Series winners since 1995 (using both the year before and after). The Rangers' 18 wins is the 6th highest two year total and all the teams with more did win the series in at least one of the years. Here are the leaders for each two year period and the teams that failed to win the series in either year are in red. There were some ties so all of those teams are listed. I think I counted and entered everything right. Let me know if you spot any mistakes.
