Prize money for the women's tennis tour will increase more than 10 percent this year.
The WTA said Wednesday that total prize money for the 54 events in 2013, not including Grand Slam tournaments, will rise from $53.3 million to $58.7 million.
The tour will return to Poland in 2013 with an event in April. Last summer, Agnieszka Radwanska became the first Polish Grand Slam finalist since 1939.
The 2014 calendar will add tournaments in Wuhan, China, and Hong Kong. Li Na, the 2011 French Open champ, is from Wuhan, which will take over hosting the event currently in Tokyo. It will feature at least seven of the year-end top 10 players.
Brazil will add a tournament in Florianopolis in 2013 and another in Rio de Janeiro in 2014.
