In 2001, she was selected as a member of New York Power, a professional soccer team in Women's United Soccer Association. In the first year, Christie played every minute of the first 18 games until tearing her anterior cruciate ligament, sidelining her for the rest of the season. In 2002, Christie bounced back to play in 1699 minutes over 19 games, and another 18 games in 2003 in addition to her national team duties. Shortly after concluding its third season, the WUSA suspended all operations. In anticipation of an eventual relaunch, WUSA preserved its rights in the team names, logos and similar properties.
