A weary Gil Morgan, newly crowned Kemper Open champion, shot rounds of 70 and 73 for one-under-par 143 yesterday at windy Woodmont Country Club in Rockville and qualified for the upcoming U.S. Open.

Tom Byrum, last year's Kemper champion who missed the cut there this year, and fellow PGA Tour player Corey Pavin, led the record 139-man field with seven-under-par 137 totals. Byrum shot 67 and 70, and Pavin had 70 and 67.

Tour player Bill Buttner was third with 68-71 -- 139.

Five area players were among the 46 who qualified for the U.S. Open at Medinah Country Club near Chicago, June 14-17. They are former Maryland Amateur champion Jim Estes of Olney (71-70 -- 141), Woodmont pro Bob Boyd of Rockville (71-71 -- 142), Webb Heintzelman of Cabin John (71-71 -- 142), Naval Academy pro Larry Ringer (69-74 -- 143) and Maryland Open champion Chris Peddicord of Baltimore (72-72 -- 144).

It was not easy for Morgan, who had to wait a while before it was determined that his score was three strokes below the cutoff point. "My old dogs are pretty tired," said the 43-year-old Morgan, who trudged 36 holes over the north and south courses. Morgan said he had only 5 1/2 hours of sleep after winning the Kemper Open and $180,000 Sunday at Avenel in Potomac. When asked if he should be forced to qualify for the U.S. Open the day after winning a tournament, Morgan said: "Augusta {The Masters} takes Tour winners. I think the Open should. But they've got their own set of exemptions . . . . That's part of the game."

Byrum seconded that emotion. "If you win a tournament on the PGA Tour . . . you should be in the Open."

Last year after winning the Kemper, Byrum had a next-day 7:30 a.m. tee time in Dallas for 36 holes of Open qualifying and withdrew because he and his family were worn out.

Last week Byrum missed the Kemper cut by one shot with 74 and 71 and said he was disappointed he could not be around for the final two rounds.

Yesterday he putted better and had little problem with the wind, which sometimes whipped to 30 mph.

Seven-year tour pro Pavin qualified for his seventh U.S. Open. He made six birdies on his final 18 holes, the south course. "I just kept the ball in play today. I didn't make many mistakes," he said.

Morgan made three birdies on each course but bogeyed his next-to-last hole (the par-4 8th hole on the north course) when he pulled a 5-iron left of the green, chipped up and missed a 3 1/2-foot putt. "I didn't putt very well today. I don't feel like I played that well, but I had to fight the wind all day," he said.

"The first 18 wasn't too bad. But the last nine holes I had to force myself to get up for a few more birdies."

Heintzelman, who missed the Kemper cut and has been struggling this year with a pinched nerve in his foot, made his third straight U.S. Open. "I'm excited," he said. "It's definitely the greatest tournament we play. I'm really pleased with the way my game has come around."

Boyd, playing the course where he is the new head pro, called his morning round of 71 on the south course "bizarre." He three-putted four times and four-putted once but still made his fourth U.S. Open.

Tour player Bob Gilder led after a morning-round 65 on the south course, but shot 75 in the afternoon and tied for fourth with three others at 140.

Former University of Maryland player George Burns (71-74) and Kirk Triplett (70-75) survived a 12-way playoff among players who shot 145 to grab the last two spots. Burns birdied the first playoff hole to get in and Triplett got the final spot with par-birdie-par.Scores of U.S. Open qualifiers, Page E6
