Former Kemper Open champion Bill Glasson (66-68) and left-hander Russ Cochran (69-65) each finished with a 36-hole total of 10-under-par 134 at Woodmont in Rockville today to lead 31 qualifiers for the U.S. Open golf tournament at the Olympic Club in San Francisco, June 18-21.

Robert Wrenn of Richmond made six straight birdies, on holes three through eight, en route to an afternoon round of 66. He was tied at 137 with PGA tour regular Roger Maltbie (70-67) of San Jose, Calif., and Gary Krueger (68-69) of Valparaiso, Ind.

It will be Wrenn's first Open in seven attempts. "I was about to give up trying," he said.

Glasson, who won the 1985 Kemper at Congressional, missed the 36-hole cut at Kemper at Avenel with rounds of 73-75 over the weekend. But after intense practice under the eye of Congressional head pro Kent Cayce, Glasson was back on the beam yesterday.

Cochran, one of several tour players playing yesterday who played in the Kemper Open, made five birdies and eagled the 15th hole in the afternoon.

University of Maryland golf coach Fred Funk shot 68-73 -- 141 to qualify for his third consecutive Open. With no sponsor, Funk will have to foot all his bills for the trip to the West Coast. "I'll pay anything to play in the Open," he said.

Webb Heintzelman (73-71) of Gaithersburg was the only other local player with a chance to qualify, but he lost out in a nine-way playoff for the final four spots. Heintzelman fell out of the playoff when he three-putted the first hole for bogey.

The playoff survivors were tour players Curtis Strange (71-73), Dave Barr (70-74), Jack Renner (71-73) and David Hobby (72-72). Hobby got in with a first-hole birdie and Strange, Renner and Barr parred the second hole.

Besides Heintzelman, the other playoff losers were Dan Forsman (74-70), Bobby Cole (71-73), Harry Taylor (73-71), and Jeff Lewis (71-73).
