ISTANBUL, Turkey - On Sunday a sellout crowd of 16,457 packed into the Sinan Erdem Dome to watch Serena Williams produce another memorable comeback to pick up her fourth TEB BNP Paribas WTA Championships title. However, the attendance and Serena's ever-growing tally of titles weren't the only noteworthy numbers posted in Istanbul?
12,385,572 - Serena's victory in the final took her annual earnings in prize money to $12,385,572. This is the third-highest total in tennis history (Novak Djokovic won $12,803,737 in 2012 and $12,619,803 in 2011). To put this in context, only 20 WTA players (not including Serena) have earned more than this sum in their entire career.
5,365 - The distance in miles between Istanbul and the venue for next year's Championships, Singapore.
82 - Serena played 82 matches in 2013, finishing up with a 78-4 win-loss record. Before this year, she had never played more than 62 in a single season.
30 - For the first time in the tournament's history both finalists were over 30. At 32, Serena is the oldest player to lift the title.
15 - Serena has now won 15 straight matches at the tournament. She still has some way to go before she catches Martina Navratilova's record of 21 consecutive wins between 1983 and 1987.
8 - For the second year in a row, eight different nations were represented at the tournament.
3 - The final has now gone to three sets seven times in the past 10 years.
2 - After her run to the final, Li Na jumps two places to a new career-high ranking of No.3. She is the first Asian player to reach the Top 3.
