Last fall, Tara Hipp won the Maryland state girls individual golf championship, and in doing so helped Gaithersburg High School take the team title.

This fall, it may be difficult for the Trojans to repeat as team champion, as Hipp is the only returning varsity letter winner, but she is determined to repeat as girls individual champion.

"I hope it's mine the next two years," said Hipp, 15, the only girl on Gaithersburg's team and one of only 12 girls who played on varsity golf teams in Maryland last year. "I'll work for it, that's for sure."

Hipp plays out of Montgomery Village, where her lowest score is 75, which she has shot twice.

Hipp has a busy golf schedule this summer in preparation for her junior year. She will play in the Bowers Junior in Springfield, Va. (July 14-17), the North-South Junior in Pinehurst, N.C. (July 28-30), and the USGA National Girls Junior in California (Aug. 4-9), where her 5 handicap makes her exempt from qualifying.

Hipp may meet some competition from Kim Cayce, 15, a sophomore-to-be at Churchill. Cayce, daughter of Congressional head professional Kent Cayce, recently shot 73 at Poolesville to win the Montgomery County junior high school championship, defeating the boys by 12 shots.

Defending champion Ken Newlin of Chantilly and two-time champion Gill FitzHugh of Army Navy are entered in the Northern Virginia Amateur, which will start today at Woodlawn in Mount Vernon. The 54-hole tournament has Friday as a rain date, and its final two rounds will be Saturday and Sunday.

Entries for the Northern Virginia Mid-Amateur can be obtained at area pro shops. The 54-hole stroke-play event for golfers 30-and-over will be held at Cedar Crest July 10-13.

A full field of junior golfers is expected for the 31st annual Bobby Gorin Memorial, July 7-10, at Woodmont in Rockville. David Patterson of Baltimore's Hillendale Country Club and Dulaney High will be back to defend his championship in the 16-17 bracket. Tom Iredell of Rockville, last year's 14-15 winner, is entered this year in the oldest age bracket.

Also on the junior schedule are 36 holes of USGA Junior Amateur qualifying at Argyle, July 3. Area qualifiers gain the tournament proper, July 21-26, at Jack Nicklaus's Muirfield Village course in Dublin, Ohio, the same course on which the Memorial PGA tournament is held each year.

The sixth annual Burdette & Fritz, Ltd., charity golf tournament will be held July 7 at Chantilly, with proceeds going to the Coors Veterans Memorial Scholarship Fund. The $50 entry fee includes golf and dinner. For further information, call 591-5200.

The annual Heroes, Inc., outing, which benefits families of policemen and firemen killed in the line of duty, will be held Thursday and Friday, July 10-11, at Indian Spring Country Club.

Ralph Bogart of Chevy Chase, Bob Lewis of Burning Tree and Hugh Botts of Fairfax are local players who qualified earlier this month for the USGA Senior Open that will start today and run through Sunday in Columbus, Ohio. Scioto will be the host facility.
