CARSON, Calif. (AP) -- Ninth-seeded Daniela Hantuchova defeated American Angela Haynes 4-6, 6-1, 6-2 Wednesday in the second round of the JPMorgan Chase Open, which lost Mary Pierce to injury.
Pierce strained her right thigh muscle while practicing Tuesday and she withdrew because of persistent pain.
She said she would get treatment for the injury, which prevents her from pushing off her right leg while serving, and decide in a few days whether she will play at Toronto next week.
"I'm just really disappointed because I feel like I've been playing really well,'' said Pierce, who won the Acura Classic in Carlsbad last week. "Unfortunately, I'm not able to serve, and definitely if this is something that gets worse (by playing), I could be out for a while.''
Pierce became the fifth seeded player to withdraw from the $585,000 tournament.
Defending champion Lindsay Davenport, Serena Williams, Vera Zvonareva and Elena Likhovtseva are sidelined with injuries.
Later Wednesday, Kim Clijsters was to play Karolina Sprem, followed by No. 2 seed Svetlana Kuznetsova against Eleni Daniilidou of Greece.
In other matches, No. 3 seed Elena Dementieva beat Samantha Stosur of Australia, 6-4, 6-3.
No. 12 seed Dinara Safina of Russia defeated Japanese qualifier Rika Fujiwara 6-2, 7-5; No. 13 Francesca Schiavone of Italy edged Shuai Peng of China, 4-6, 7-6 (1), 6-4; and No. 17 Marion Bartoli of France beat qualifier Tiantian Sun of China, 6-7 (4), 6-3, 6-1.
Pierce was replaced in the draw by lucky loser Saori Obata of Japan, who lost to Italian qualifier Tathiana Garbin 6-4, 6-1. American Lisa Raymond defeated qualifier Aiko Nakamura of Japan 2-6, 7-6 (5), 6-3.
