Larry Ringer does not often escape from his time-consuming duties as director of golf at the Naval Academy course and coach of the Navy golf team, but when he does get out, he usually posts some impressive scores.

"This place is so busy, it's scary," said Ringer, 42, who will defend his Middle Atlantic PGA Championship, Aug. 24-26 at the demanding Golden Horseshoe course in Williamsburg.

Ringer, a two-time Maryland Open champion, said his putting touch has returned this season, resulting in a Maryland State Pro-Am championship (he teamed with Mike Cumberpatch) and five Middle Atlantic PGA wins. He also played in the Kemper Open and the Anheuser-Busch Classic, both PGA Tour events.

Ringer is proud of the way he negotiated rounds of 72-72-71 for 215 and a victory last year at Golden Horseshoe. "Golden Horseshoe is as good a challenge as I've ever had," said Ringer. "It requires one of the best things that you can ever have on a golf course and that's patience. The key for me in winning was my ability to play the par 3s in 1 under par. For me to be able to do that on that great golf course was quite a feather in my cap.

"I'm looking forward to the Golden Horseshoe. It sounds nice to go down there as defending champion."

Richmond's Robert Wrenn dominated the other PGA Tour pros in the recent Buick Open with rounds of 65-63-67-67 -- 262 for a seven-stroke victory.

Wrenn tied the largest victory margin this year, set by Tom Kite in the Kemper at TPC at Avenel, and Wrenn's 26-under-par total was one shot away from a long standing PGA Tour record.

Wrenn gave an indication of his ability in June U.S. Open qualifying at Woodmont in Rockville, where he played with Woodmont pro Gary Marlowe and made five straight birdies for 7-under-par 65, and left Marlowe marveling at his abilities. That was the first time Wrenn qualified for the Open in several attempts, and he said at the time that he almost had given up all hope of making it.

Marlowe, who played the PGA Tour in 1984, will try to make it again this fall in qualifying school.

A son and his mother recently won the men's and women's club championships at Woodmont.

Tim Landres won the men's club championship, 1-up, in 36 holes over Ken Bubes. His mother, Leslie Westreich, won the women's club title with a 54-hole total of 277 . . . Long hitter Eric Egloff of Rockville, who beat Marty West in the semifinals and Tim Moylan in the final to win the recent Washington Metropolitan Golf Association championship, plans to move to Florida and play on the mini-tour circuit there . . . Talk about rapid improvement in golf, Ray Bellamy of Cheverly, who lost in the finals of the recent Worsham Memorial, reduced his handicap from 33 to three in just five years. Bellamy, 18, is a former DeMatha High School golfer who now plays for Millersville (Pa.) University. . . . John Joy of Washington advanced the farthest of any black golfer in the 37-year history of the Worsham tournament when he made it to the semifinals, before losing to eventual winner Steve Woda. Joy, an excellent shotmaker who plays out of East Potomac, plays No. 2 on the St. Augustine's College team in North Carolina.
