Two thousand five hundred and one matches, across 59 tournaments and five continents. While numbers never tell the whole story, when it comes to the 2015 WTA season, they certainly make for a good read.

So at the start of the new year, SAP and wtatennis.com wave goodbye to the old one with a countdown of some of its more eye-catching figures.

10,582,642 – Despite missing the final few months of the season, the peerless Serena Williams still managed to pass the $10 million mark in prize money for just the second time in her career. 

230 – The number of minutes needed by Francesca Schiavone to defeat Svetlana Kuznetsova in the second round of the French Open, making it the longest match of the season. Honorable mentions go to Petra Martic and Wang Yafan for their three hour, 27 minute effort in Dalian.

130 – World No.130 Teliana Pereira was the lowest-ranked player to win a title when she went all the way in Bogotá.

128 – The speed in miles per hour of the fastest serve of the year, unleashed, unsurprisingly, by Serena Williams at the BNP Paribas Open.

81.1 – Serena’s 120mph-plus bombs helped her win 81.1% of her service games.

79 – Karolina Pliskova can confidently lay claim to being the busiest women in tennis, playing more matches (79) on tour than anyone else. 

72 – By common consensus, Daria Kasatkina is the next big thing in Russian tennis. After enjoying a distinguished junior career, a string of impressive showings has aided a charge up the rankings that saw Kasatkina finish a year she started well outside the Top 300 perched handily at No.72.

51.9 – Sara Errani may not possess the most fearsome of serves, but she more than makes up for it when receiving. Last year she won a higher percentage of games (51.9%) and points (50.8%) on return than any other player.

46 – A few days after upsetting Ajla Tomljanovic in Seoul, the evergreen Kimiko Date-Krumm celebrated her 46th birthday.

31 – Errani was taken to three sets on 31 occasions in 2015, underlining her reputation as one of the game’s most dogged competitors by prevailing in 19 of them.

17 – At 17 years and five months, Ana Konjuh‘s victory in Nottingham saw her crowned the youngest WTA singles title winner in nearly a decade.

5 – Angelique Kerber enjoyed a return to form in 2015, picking up four titles, in Charleston, Stuttgart, Birmingham and Stanford. However, she was still unable to match Serena’s WTA-leading tally of five (Australian Open, Miami, French Open, Wimbledon, Cincinnati).  

0 – Number of times Belinda Bencic lost in her five encounters against Top 5 players, including that memorable upset of Serena Williams en route to the Toronto title.
