Matt Sughrue birdied four of the first five holes and teamed with Bethesda clubmate Eddie Offterdinger for a tense 1-cup victory over Henry deLozier and Perky Cullinane in a quarterfinal match of the Belle Haven Four Ball yesterday.

In this morning's semifinals the Bethesda collegians play former Virginia Amateur champion Sam Wallace and son Sam Jr. In the other semifinal, 1972 U.S. Amateur and 1975 British Amateur titlist Vinny Giles and Dave Wysong face Chip Heyl and Tom White.

Defending champions Steve Fellinger and Mike Richter of the University of Maryland and the two medalists teams were eliminated in yesterday morning's opening round.

The long-hitting deLozier reached the par-5 first extra hole with a drive and a four-iron and two-putted for a birdie to give the Columbia team a 19-hole win over Fellinger-Richter.

"We just didn't make enough birdies," said the slim, left-hander Fellinger.

Steve Smith of Maryland and Phil Pizzoferrato of Montclair, who shot 66 to share the qualifying medal, could not get anything going yesterday. They bogeyed five holes and fell victim to the Wallaces of Williamsburg, 2 and 1.

The other medalist duo, former Belle Haven winner Hank Miracle of Andrews Air Force Base and Ed Heimann of Cincinnati, lost to Heyl of Reston and White of Army-Navy, 4 and 3.

In the quarterfinals, Heyl made a hole in one using a three-iron on the downhill 10th to give him and White a one-hole advantage that helped them beat Neff McClary of Fairfax and Wilson Dickerson of Midlothian, Va., 1 up.
