Singapore was chosen as the host city to replace Istanbul for the WTA Championships which will be staged in the new Singapore Sports Hub that is due for completion in April.
The Road To Singapore, which sees women players compete across 54 tournaments in 33 countries, was launched in Singapore by Evert along with Australian Open semi-finalist Eugenie Bouchard.
The WTA Championships, of which Evert is an ambassador, will feature seven days of competition and a further three days of associated supporting events.
There will be eight teams in the doubles and also a WTA Rising Stars Exhibition and WTA Legends Exhibition during the opening Fan Festival weekend.
"We are excited to announce new elements of the WTA Championships that will engage the fans of women's tennis with the WTA stars and turn our year-end event into a premier sports entertainment property," said Stacey Allaster, chairman and ceo of the WTA.
"The WTA is committed to the long-term development of the sports community in Singapore and through numerous programmes we've put in place, we look forward to growing our fan base and empowering people of the region through sports."
