Gymnast Stephanie William of Bethesda probably will not compete in the Nation's Capital Cup gymnastic meet Saturday at the University of Maryland's Cole Field House. A press release had said William would compete, but her coach, Greg Weiss, said yesterday William was in Santa Ana, Calif., for a weeklong training session and that it was "very very unlikely that she be in the meet."

Gymnasts Stephanie William of Bethesda and Jenny Huff of Potomac will compete head-to-head for the first time at the Nation's Capital Cup gymnastics championships Saturday at the University of Maryland's Cole Field House.

The competition will involve eight of the country's top independent clubs, including Willim's team, The M.G.'s of Silver Spring, and Huff's squad, the Marva-Teens of Rockville.

Each team member will compete for individual awards, regardless of age, in the four Olypmic events: balance beam, parallel bars, vault, floor exercise. They also will view for an overall award. In most of the state, regional and national meets gymnasts compete for awards in their specific age group.

Willim and Huff have dominated Washington-area meets for the last two years. But because they compete in different age groups, they have never met in competition.

Willim, already, a winner in international competition, is 13 years old and competes in the junior elite class (ages 11-14). Huff, the 1977 senior regional champion, is 15 and a member of the senior elite division (14 and up).

Team competition begins at 1:30 p.m. with the individual championship final slated for 7:30 p.m. Separate admissions will be charged for each session.
