[1] Zemina was also a member of a national record-setting team in the 200-meter freestyle relay (short course) in 1985.

[4] Zemina competed for United States national teams at international swimming tournaments in Germany (1983), Sweden (1984), Japan (1985), the Soviet Union (1986) and South Korea (1988).

[1] She became the center of a controversy at the 1985 World University Games in Kobe, Japan, when two winning U.S. relay teams of which she was a member were disqualified because she was too young to compete.

Zemina, who had turned 17 on February 15, missed the January 1 cutoff by several weeks, and the error was overlooked by USA Swimming authorities.

[6][7][8] At the 1988 Summer Olympics in Seoul, South Korea, Zemina swam for the third-place U.S. team in the preliminary heats of the women's 4×100-meter freestyle relay; together with Mary Wayte, Mitzi Kremer, Laura Walker, Dara Torres and Jill Sterkel, she received a bronze medal.
