In addition to his Grand Prix event triumph in São Paulo in 1990, when he beat Jaime Yzaga in the final despite dropping the first set, Weiss took three Challenger event titles - Itu-São Paulo in November 1992; Palm Springs in 1993; and Granby in 1995.
In arguably his best performance to date, he did manage to reach the semi-finals of the Challenger event at Segovia in 2003, where he played Rafael Nadal.
