Belarusian Victoria Azarenka, the world's top-ranked tennis player, will compete in the 2013 edition of the WTA event in this northern Mexican city.

Hernan Garza, director of the Monterrey Open, which will offer $235,000 in prize money, said in a press conference that last year's Australian Open winner and U.S. Open runner-up would be in the draw.

He added that the tournament hopes to attract another top 10 player but that already the participation of three Russians - 14th ranked Maria Kirilenko, 36th-ranked Anastasia Pavlyuchenkova and 96th-ranked Vera Zvonareva, runner-up at both Wimbledon and the U.S. Open in 2010 - has been confirmed.

"We're happy about what we've achieved over these five years of the tournament. Every year we've had a better response and high-level players," Garza said.

Hungary's Timea Babos was the surprise champion of last year's Monterrey Open, rolling to the title with wins over 3rd-seeded Romanian Sorana Cirstea in the round of 16, 2nd-seeded Italian Sara Errani in the semifinals and Romanian Alexandra Cadantu in the final.

The other winners of this hard-court event were Pavlyuchenkova in 2010 and 2011 and France's Marion Bartoli in 2009. EFE
