=== Wozniacki wins opener in Sofia ===
Sofia, Bulgaria (Sports Network) - Former world No. 1 Caroline Wozniacki was
among Tuesday's round-robin winners at the $750,000 Tournament of Champions.
The top-seeded Wozniacki, of Denmark, waltzed past fifth-seeded Su-Wei Hsieh
of Taipei 6-2, 6-2 on the indoor hardcourts at Armeets Arena. Wozniacki and
Hsieh are both two-time champions on the WTA this year.
Also on Day 1, fourth-seeded Italian Roberta Vinci whipped seventh-seeded
Slovak Daniela Hantuchova 6-1, 6-2 and eighth-seeded Bulgarian crowd favorite
Tsvetana Pironkova overcame sixth-seeded Chinese Zheng Jie 2-6, 6-4, 7-6
On Wednesday, Wozniacki will battle Vinci, while second-seeded Russian Nadia
Petrova will take on Zheng and third-seeded Russian Maria Kirilenko will
be opposed by Pironkova.
The Tournament of Champions is the finale for the WTA's International Series,
with the six highest-ranked players who have won an International title this
year -- and two wild cards -- comprising the eight-woman field. The four-
player Serdika Group features Wozniacki (1-0), Vinci (1-0), Hsieh (0-1) and
Hantuchova (0-1), while the four-player Sredets Group features Petrova (0-0),
Kirilenko (0-0), Zheng (0-1) and Pironkova (1-0).
The tournament format will see two round-robin groups play out over the first
four days, with the semifinals on Saturday and the final on Sunday.
Serbian star Ana Ivanovic topped Spaniard Anabel Medina Garrigues for her
second straight title at this event in last year's finale in Bali, which also
hosted the tournament in 2009 and 2010.
The current host Sofia will also stage this event next year and in 2014.
