Haverford High has won the Pennsylvania Ultimate Frisbee boys' championship for the first time in the program's five-year existence.

The Fords beat neighboring Radnor, 15-8, near Pittsburgh last weekend for the title in the seven-on-seven competition that drew 16 teams from around the state.

Lower Merion beat out 13 other schools for the girls' championship.

Haverford won 25 of 30 matches during the season, including a seven-match winning streak at the end.

Ultimate Frisbee is similar to football in that the disk is passed with the goal of reaching an end zone.

Senior Tyler Kunsa has been a member of the Haverford team for all five years, starting when he was in eighth grade.

"My older brother Jason helped start the team when he was a sophomore," said Kunsa, who is headed to the University of Pittsburgh, where he plans to play. "It might not have all the serious competitiveness of some other sports, but it's fun."

Simon Feeman, another senior, is in his second season with the Fords, but he has been around the sport all his life.

"My mom has played Ultimate Frisbee, so I've been around the game all my 17 years," he said. "She even played when she was pregnant with me. I like it because of the high-flying moves that you make."

Dalton signs. Villa Maria Academy diver Grace Dalton, who won the District 1 Class AA championship and finished ninth at the PIAA meet, has signed a letter of intent to continue her career at Navy.

Dalton, an ex-gymnast who was injured, didn't begin diving until her freshman year at Villa, but she came a long way in four years, Villa swim coach Cathy Hay said.

"She's a great kid and a great golfer," Hay added. "She plays on our golf team. She has experience diving at three meters. I think that's why Navy was interested in her."

Rugby streak ends. The Downingtown Rugby Football Club's under-19 boys' team lost its three matches and finished eighth in the eight-team national championships, held May 21 to 23 in Sandy, Utah.

The Dingoes lost their May 21 games by 33-0 to Belmont Shore of Long Beach, Calif., and 15-10 to Union County (N.J.). The next day, they were edged, 15-10, by the Alpharetta (Ga.) Phoenix in the seventh-place game.

"The last two were extremely close, as we lost each during the last seconds," Downingtown coach Mike Drill said.

The Dingoes entered the tournament with a 12-0 mark, winning the Eastern Pennsylvania Rugby Union, state and Mid-Atlantic Rugby Football Union titles. United, of Alpine, Utah, won the national tournament.
