Skeeter Heath of Williamsburg shot 70 in his morning round at Belle Haven and added 71 at Army Navy, a course he had never seen before, to finish at 141 and lead eight golfers in U.S. Open local qualifying yesterday. Eighty players competed.

Heath gained the U.S. Open sectional qualifying June 8 in Memphis. The other seven survivors advance to the sectional June 7 at Bethesda Country Club. The U.S. Open is at Pebble Beach (Calif.), June 17-20.

Heath won the qualifying medal by five strokes. After shooting two-under-par 70 at Belle Haven, he birdied holes No. 3, 4 and 5 at Army Navy

Heath had his PGA Tour card yanked twice because he did not earn the required minimum, but his game has picked up since he shot a course-record 63, which included a 28 on one nine, in qualifying for the Houston Open three weeks ago. He has earned about $8,000 on the 1982 tour.

John McNaney of Rolling Road finished with 16 straight pars at Army Navy for second, 72-146. Jim Fitzgerald, assistant pro at Columbia Country Club, tied amateur Dave Tolley of Roanoke for third at 147.

A.J. Duncan of Westwood shot the day's best round, 69 at Army Navy, and tied for fifth with Clem King of Farmington and amateur Bob Friend of Richmond, 148.

Marty O'Rear of Belle Haven sank a 10-foot birdie putt on the par-5 first hole to win the final spot in a four-way playoff with amateur Dave King of Bethesda, Ken Leber of Loudoun and Larry Rentz of Newbridge. All had shot 149.
