Kim Clijsters continued her comeback from a wrist injury with an impressive 6-2 6-1 win over Nicole Pratt at the Pacific Life Open in Indian Wells.
The former world number one, who now languishes outside the top 100, is playing only her second event since a four-month spell on the sidelines.
"For three or four weeks I was thinking I might not be able to play again," she admitted on Wednesday.
"The doctors were saying that as well, but I wasn't ready to quit."
Clijsters began her comeback at February's tournament in Antwerp, reaching the quarter-finals in her home country.
"This is my first overseas tournament (of 2005)," Clijsters said after beating Pratt in 49 minutes.
"I felt good, especially once I got going. I feel like I am getting back into my match rhythm and I am happy that my backhand is still there."
All 32 seeds, including Lindsay Davenport, Amelie Mauresmo and Maria Sharapova, have been given first-round byes.
Clijsters' fellow Belgian Justine Henin-Hardenne will not defend her Indian Wells title as she recovers from the knee injury that caused her to miss the Australian Open.
Henin-Hardenne is expected to make her WTA return at the Nasdaq-100 Open in Miami, which begins on 21 March.
