A solution to Challenge #137 has been posted HERE!

Aside from completing a Weekly Challenge, there's nothing more thrilling than World Series baseball!  This weeks' challenge asks you to analyze data on previous World Series match-ups.  Use the provided data to determine each team's number of World Series appearances, list the years in which each team won the World Series, and calculate each team's winning percentage based on their World Series appearances. 

The play by play...
