The last of the year's four Grand Slam events has been completed, providing an opportunity to issue updated grades for the top tennis stars in 2013.
Things are starting to come into focus, with Serena Williams and Rafael Nadal establishing themselves as the top players this year. But does either deserve an "A+" for their work this year?
Our grades are based on 2013 competition only. Wins and losses were the primary factors used in sizing up each player's year, with Grand Slam events carrying the most weight. However, the expectations for the player, as well as the direction of the player's career, were also considered when issuing the grades.
We chose seven women and seven men who warrant star status at the moment and counted down to the player who received the highest grade.
