Top-seeded Victoria Azaranka beat seventh-seeded Ana Ivanovic 6-0, 4-6, 6-3 on Saturday to advance to the final in the Southern California Open.
Azarenka, the Belarus player ranked No. 3, won a sloppy match against the Serb as both players committed more unforced errors than hit winners. The two-time Australian Open champ will face fifth-seeded Sam Stosur of Australia, a 7-6 (2), 6-3 winner over Virginie Razzano of France.
''When you play a tournament, it's never going to be just easy matches,'' Azarenka said. ''You have to go through the tough battles and this was one of the days. I'm just happy with the end result that you can overcome things and still find a way to win, that's the most important.''
The semifinal win will propel Azarenka, the former world No. 1, past Maria Sharapova of Russia into the No. 2 slot when the new rankings come out Monday.
Azarenka hit 21 winners and had 31 unforced errors, while Ivanovic had 31 winners and 47 unforced errors.
''I gave her too many easy points, especially at the important moments, like 40-all or deuces,'' Ivanovic said.
Azarenka, playing her first event since withdrawing from Wimbledon because of a right knee injury, scored the first of her two service breaks of the final set to take a 3-2 lead. When Ivanovic had four unforced errors in the ninth game, including a backhand into the net on the final point, Azarenka secured another break for the win.
''She's a really big shot maker,'' Azarenka said about Ivanovic. ''She loves to take her opportunities and just bang the ball and find those deep shots. The key for me was not to let her take those shots and be the one who's putting on pressure.''
The first set wasn't as lopsided as the score indicated. Each of the first four games were long and drawn out. But after Azarenka broke the Serb's serve at love in the fifth game, she quickly held serve to win the first set.
Ivanovic opened the second set by holding her serve, a big improvement from the first set when she made just 43 percent of her serves and won only 53 percent of her first serve points.
Ivanovic clearly seemed to gain confidence as she won the first three games and took a 4-1 lead. But Azarenka then rolled off the next three games to tie the set before Ivanovic closed it out by holding serve, then breaking Azarenka's serve at love to force a third set.
