The 2013 WTA season is over. However, the 2014 season gets underway in less than two months. Tune-up tournaments for the first Grand Slam, the Australian Open, begin in December. Meanwhile, players are trying to fine-tune their games.

This list looks at the Top 10 players on the WTA tour and singles out a specific improvement they need to make before 2014.
