WTA Chairman and CEO Stacey Allaster will visit Monterrey this week, Singapore the week of February 25 and Tianjin the week of March 4. The winning host city will be announced in April.

"The WTA Championships provide cities around the world a stage on which their cities can be showcased. I am very pleased with the amount of international interest the Championships' bidding process has received," Allaster said. "I look forward to meeting with each finalist city and having the opportunity to review, in-person, the details of each bid."
