                === Wozniacki to play Petrova for TOC crown ===
 
 Sofia,  Bulgaria (Sports  Network) -  Top seeds  Caroline Wozniacki  and Nadia
 Petrova  will meet  for  the  Tournament of  Champions  title  after both  won
 semifinal matches on Saturday.
 
 The top-seeded Wozniacki rolled to a 6-4, 6-1 victory over Bulgaria's Tsvetana
 Pironkova  in the first match, much to the disappointment of the crowd, before
 the  second-seeded Petrova  gutted out  a 6-7  (8-10), 6-1,  6-4 triumph  over
 Italy's Roberta Vinci.
 
 Wozniacki  began pulling  away midway  through the  first set,  turning a  4-4
 deadlock  into a  rout by winning seven  straight games. She has won a pair of
 titles this year, both since a first-round flameout at the U.S. Open.
 
 The  Denmark native  and former  world  No. 1  lost to  Irina-Camelia Begu  at
 Flushing  Meadows,  but followed by winning  the Korea Open in late September.
 She then captured the Kremlin Cup last month for her 20th career title.
 
 Wozniacki,  who is  2-1 in finals this  year and 20-11 overall, will return to
 the top 10 when the new rankings are released next week.
 
 Petrova,  meanwhile, lost  a tough  tiebreaker to  end a  70-minute first  set
 Saturday,  then rolled in  a 30-minute second with a pair of breaks and picked
 up the only break of serve in the third to finish the 2-hour, 42-minute match.
 
 The 13th-ranked Russian will try for her 13th career title on Sunday and third
 of  2012.  She won  the Wimbledon  tune-up in  Den Bosch  and captured the Pan
 Pacific Open in September. Sunday will mark Petrova's 24th career final.
