Allie Ritzenberg rarely had spoken to his brother, Nate, the last several years and had not played a tennis match against him since 1936.
Then on Thursday, the brothers met in the United States Tennis Association's National Clay Court men's 80s championship round of 16 held at Army Navy Country Club in Arlington.
Allie Ritzenberg, director of the St. Albans tennis club, defeated his older brother, 6-0, 6-3, to advance to the quarterfinals. He plays Irving Converse of Ohio today at 10 a.m.
"It was very traumatic, the sibling rivalry that goes on," said Allie Ritzenberg, who at age 80 is two years younger than his brother. "I think I've never concentrated as hard as I did."
The match was moved indoors to a hard court because of the bad weather caused by Hurricane Floyd. The switch from the clay court benefited Allie Ritzenberg, who is ranked No. 4 in the singles draw. His brother was unranked. He said it took his brother some time to become accustomed to the different surface.
Nate "is a clay-court player, very steady," Allie Ritzenberg said. "He still uses a wooden racket. I probably hit harder than most seniors."
Allie Ritzenberg also is playing doubles with Powell Taylor of Norfolk. He and Taylor are seeded No. 2.
