CHARLESTON, S.C. -- No matter how the final match goes, there will be a surprise champion at the Family Circle Cup.
Petkovic rallied in the final two sets to defeat sixth-seeded Eugenie Bouchard, 1-6, 6-3, 7-5, while Cepelova came back from 4-1 down in a third-set tiebreaker to oust 17-year-old Swiss qualifier Belinda Bencic, 6-4, 5-7, 7-6 (7).
Petkovic appeared overwhelmed by the 20-year-old Canadian early on, losing seven straight games and trailing 3-2 in the second set. That's when the German took control, winning four consecutive games to force a decisive set.
Petkovic was trailing 4-2 in that one before digging in a final time and breaking Bouchard's serve twice down the stretch to advance to her first championship since Washington last August where she fell to Magdalena Rybarikova in straight sets.
Petkovic broke down and cried with a towel over her head after the match, happy she was again in this position after the past three years dealing with injuries to her ankle, knee and back that caused her to miss nine months on tour.
"I was just so relieved and I was proud that I came back from all these injuries, and I never thought that I would play finals in the big tournaments again," said Petkovic, who hadn't gotten past the quarterfinals in her six previous tournaments this season.
Cepelova, 20, hadn't ever been past the quarterfinals since her
Not that her semifinal was easy. Cepelova squandered one match point while up 5-4 in the final set, then two more in the tiebreaker before Bencic sailed a shot long to end things.
Cepelova said she carried the confidence she got from beating Williams into the rest of the week. "I think now on these matches that I won, I try to keep playing like against Serena," she said.
Petkovic's father, Zoran, played college tennis at South Carolina and was among the Gamecocks top players with an 18-8 singles record in 1982. She hopes to give her family more reason to celebrate their connections to the Palmetto State.
