DuVal baseball coach David Schaffer died early yesterday morning at Georgetown University Medical Center 11 days after suffering what doctors believe was a bleeding stroke, his wife, Mary, said last night.

Schaffer, 48, suffered the apparent stoke on March 24 while fixing equipment at a law office. He fell into a coma and underwent surgery at Georgetown, but never regained consciousness, Mary Schaffer said. He was taken off life support on Tuesday night, when doctors told Mary Schaffer her husband of 21 years had "less than a 1 percent chance of surviving," she said.

"He wasn't breathing by himself, but most of all if something like this was going to happen, I wanted something positive to come out of it, and the doctors told me his organs were in good shape to be an organ donor," Mary Schaffer said. "By taking him off life support, he could be an organ donor and help save the lives of other people."

Schaffer is survived by his wife, four children and one grandson. No funeral date has been set.

Schaffer repaired office equipment for a living and did not teach at the Lanham school. He had coached at DuVal for the past five years, and he had coached youth baseball and soccer for the past 15 years, his wife said.

"I've known Dave for the past four years and he was the best friend I had in Prince George's County," said Central baseball coach Franco Crispi, whose players prayed with Surrattsville's players following the teams' game yesterday. "This goes beyond baseball: Dave was a great man, a great husband and a great father."

Mary Schaffer said DuVal Athletic Director Carol Konrad told her the team would wear black arm bands and hold a moment of silence before every game.

"He worked hard to make the kids' lives at DuVal better," DuVal football coach Joe Lewis said. "He was always out on the field. He made the kids feel like they were playing at Camden Yards."
