Medalist Sam Randolph, suffering lower back pain from the 15th hole on, beat Jay Sigel, 2 and 1, but a 1 1/2-hour rain delay forced suspension of play due to darkness in the other three quarterfinal matches of the U.S. Amateur Championship at West Orange, N.J.

Defending champion Scott Verplank and Jack Kay were tied after 17 holes. Chip Drury was 1 up after 17 over Todd Hamilton, and Peter Persons led Sam Farlow by one after 16.

They'll resume this morning, then play the semis in the afternoon. "I'm happy they called it," said Verplank. "But I've never been in a one-hole match before."

In third-round matches yesterday morning, Verplank withstood a late charge by Walker Cup teammate Bob Lewis, and won on a first playoff hole . . .

Jay Delsing, a PGA Tour rookie, played an error-free, nine-under-par 62 to improve his first round by 11 shots, tie the tournament record and tie for the lead before the $300,000 B.C. Open was delayed by rain at Endicott, N.Y.

Delsing's spectacular tour of the En Joie layout put him at 135 with Doug Tewell, 68-67.

They completed play before a 2 1/2-hour rain delay and waited while challengers with later starting times faltered. Twenty players will have to finish the second round this morning . . .
