Smith competed on the WTA Tour from 1990 to 1992 and from 1995 to 2000. Her highest achievement was in reaching the fourth round at the Wimbledon Championships in 1998, when she beat Anne-Gaëlle Sidot, Mariana Díaz Oliva and former champion Conchita Martínez before losing to eventual runner up Nathalie Tauziat. In so doing she picked up an ankle injury that required her to have two operations and spend four months in plaster; this effectively ended her career. She peaked at No. 55 in the WTA rankings before the injury curtailed her climb up the rankings.
