No, the Jordan sisters are not a singing group, rather two talented golfing teen-agers who hone their games at Army Navy Country Club Fairfax, less than a mile from their home.

Lene, 18, and Michelle, 16, play to 5 handicaps.

Two weeks ago Michelle finished 15th in the Junior World tournament at Torrey Pines in San Diego and was selected for the U.S. team in the international team matches against teams from Canada and California. She is entered in the U.S. Golf Association girls junior in Wilmington, Del, Aug. 7-12 Cathy Eyre of Reston and Karen Jones of Rockville also made the field.

Lene also has played in scads of tournaments, including the Junior World (she was too old this year) and will attend Brigham Young on a full golf scholarship this fall.

The Jordans moved here three years ago from Kansas. Their father is Army Lt. Col. George Jordan, currently stationed at the Pentagon.

"I was born in Germany, moved to Georgia, Albuquerque, Monterey, Kansas and here," said Michelle, who appreciates the scenery change. "Oh, and Arizona was in there somewhere."

Louisiana State's golf team will have a Washington-area flavor with Gary Marlowe of Norbeck, Ian Noel of Chevy Chase and Wayne DeFrancesco of McLean expected to make the squad.

DeFrancesco, who transfered to LSU from Wake Forest, won last week's D.C. Amateur. Marlowe, 19, became the youngest ever to win the Maryland Open earlier this month, and Noel won last year's Metro schoolboy title.

Coach of the Tigers is former University of Maryland mentor Dave Sigler.

Tour players Tom Kite, Joe Inman, Bobby Wadkins and Bobby Walzel joined their buddy, Dennis Satyshur, in an exhibition match on Monday at Columbia Country Club. The several thousand dollars raised went to the Fred McLeod scholarship Fund, for school tuition of Columbia caddies.

Inman and Wadkins, younger brother of PGA champ Lanny Wadkins, scorched it with 65s, followed by Kite, 68, Stayshur, 71 and Walzel, 73, before a gallery of about 400.

J. C. Snead will be out of PGA action for about two more months with a broken wrist sustained the week after his tied-for-second finish in the U.S. Open in Denver.

Snead had loaded 56 bales of hay onto a wagon in Hot Springs, Va., with the help of his father. As his father started to drive away, the wagon hit a hole, and J. C. and a half-dozen bales flew off the rear.

"One of the bales hit the ground and bounced up to hit me," he said. "I threw my left arm out for protection, but the bale hit me in the chest. That's when I broke it, just below the wrist," said the former Washington Senator baseball prospect.

Bill McFerren Sr., bettered his age for the umpteenth time with an even-par 71 and won the seniors championship at Montgomery Village. He will be 74 next month.

In another senior feat, Ray Willett, 60, used only two putts in burdieing the final four holes at his home Brooke Manor for 68.

Willett blasted from a greenside trap into the cup for birdie on the 15th, canned a 10-foot birdie putt on the par-5 16th, used his trusty sand wedge to blast into the hole again on the 17th and made a three-footer on the final green. The former Woodmont assistant pro, who regained his amateur status in the early '50s, has twice shot 65 there.

Elvin Hayes of the NBA champion Washington Bullets will serve as honorary chairman of the Middle Atlantic PGA Open at Hobbit's Glen and All-view, Aug. 21-23.Proceeds go to the Mid-Maryland Lung Association.
