The Marvateens women's gymnastic club of Rockville won the Capital Cup yesterday at Montgomery College, and team member Marni Rager won an individual gold on the uneven parallel bars.

The team title marked the first time the host Marvateens have won the Capital Cup since 1979. Marvateen Coach Gary Anderson said, "Since our top girl Lisa McVay was (competing) in Reno, I expected maybe third or fourth. But this particular (day), we were the better team."

Better than the Parkettes of Allentown, Pa., who had been expected to win. But on Saturday, the Parkettes' star performer, Tracy Hinkle, suffered a back injury during her first event. "Certainly that was a factor," Anderson said.

Another factor was Rager, of Silver Spring. Her uneven bar routine scored 18.7 out of 20 to give her first place.

The Parkettes' Tracy Calore of Allentown won a gold medal for her vaults. She scored 19.8 with a very difficult and spectacular move. Within about two seconds, she hit the springboard, made a half-twist before hitting the horse, then dismounted with a full twisting somersault in a straight-body position.

The Parkettes' Tracy Butler of Allentown won the balance beam with 18.5; first place in the floor exercise went to Stacy Gunthorpe, 12, of Plainfield, N.J. Gunthorpe, who is 4-feet-1, scored 19.05.

Cheryl Kaneshiro of Rockville, who was expected to win the uneven bars, was sixth. During her floor exercise, she lost her balance twice, for a full-point penalty, and scored 8.5 for that event.
