Nobody predicted a Houston-Chicago White Sox series back in 2005.
The teams had great pitching, such as Roger Clemens and Andy Pettite for Houston and Mark Buehrle, Jon Garland, Freddy García, and José Contreras for Chicago.
The White Sox swept the series and that was also a shock. I had predicted a tough 7-game series.
The White Sox returned to the post season in 2006 but went out early. Houston did not return until 2015.
