The White Sox now advanced to the World Series, where they would take on the National League champion Houston Astros. The White Sox' appearance in the World Series was bittersweet for longtime franchise star Frank Thomas. One of the most popular and productive players in the franchise's long history, Thomas would finally be going to a World Series in his 16th major league season. However, due to injury, Thomas would be unable to participate except as an observer, and his contributions to the White Sox in 2005 were limited.
