We all can probably name who finished as the No. 1 of each year since the ATP rankings started, so that's not much of a challenge. How about naming all of the players who finished in the Year-End Top 4 from 1973 to 2014? Making this quiz was fun, since there were quite a few names that had been forgotten and I was surprised to see who had finished the year so high. Just punch in the last name and see how many of the 168 players you can remember. Click the pic to go to the quiz.
