Bill Glasson, winner of four PGA tour events including last year's Doral Open, and Lori Garbacz, winner of the 1989 LPGA Tuscon Open, are among 17 touring professionals committed to compete in the sixth annual Ronald McDonald House Pro-Am, Monday, July 9, at Westwood in Vienna.

Others expected in the field, which will also include 17 Mid-Atlantic PGA members and 136 amateurs, are Donnie Hammond and Leonard Thompson, both PGA winners last year, and 1988 Kemper Open champion Morris Hatalsky.

Some amateur spots still remain. More information can be obtained from tournament director Regina Schewe at (703) 264-9080. Bethesda's New Order

The order of Bethesda Country Club's holes will be changed, making for a more exciting series of finishing holes for the richest event in the history of women's golf, the $1 million Mazda LPGA Championship, July 26-29.

Nancy Lopez, Betsy King, Pat Bradley, Beth Daniel, Patty Sheehan and Ayako Okamoto and the world's top women golfers will play the regular back nine as their opening nine to better facilitate grandstands and television vantage points on the dramatic closing holes of the event, one of the LPGA's major championships.

Swinging around to their final nine, the golfers will play what were formerly holes one through six, and then they will play the ninth hole. After finishing the ninth hole, players will be carted back to the eighth tee. They will play the eighth hole as their 17th, and they will finish on the par-4 380-yard seventh hole.

The new finishing hole will feature an approach shot from the top of a hill down onto the green. The finish will offer a more panoramic view for the fans, with more room around the putting surface to allow for grandstands and television cameras. Boyd is Winner

New Woodmont pro Bob Boyd shot 64 to win the recent Middle Atlantic PGA/Neediest Kids Pro-Am at Lakewood Country Club in Rockville. Vice President Dan Quayle made an appearance and played one hole in the event which raised about $60,000 for Neediest Kids, Inc. Part of the money went to fund free golf clinics and is tied into the D.C. Public Schools Get Hooked on Golf program.

Host Lakewood pro John Hafera, co-founder of the tournament with WJLA-TV's Paul Berry, was named the Jimmy Hodges Golf Shop Operations/Golf Digest junior promotor of the year. Hafera, MAPGA junior golf chairman, coordinated free clinics at East Potomac and Reston. Juniors in Full Swing

The area junior season gets into full swing with several prestigious upcoming tournaments -- the Bowers Junior at Springfield, July 9-12; the Gorin Junior at Woodmont, July 16-19; and the Worsham Memorial at Glenn Dale, July 23-25.

Tim Burnett, last year's Gorin champion from Rockville and Manor, will be back to defend his title at the Rockville club.

College student Jon Krinn is eligible to play in the Worsham near Greenbelt, which has an extended age limit to 20. Also entered is last year's runnerup, Mark Jansen of George Mason University. The Worsham, like the Emmet Schoolboy which concludes today at Westwood, will be played for the first time with a stroke play format instead of match play.

The Bowers, which includes top players from this area and surrounding states, will remain match play. WMGA Starts July 12

Montgomery Country Club near Olney will host the Washington Metropolitan Golf Association Men's Amateur, July 12-15. The WMGA, formerly the District Amateur, started in 1914 and is the second oldest amateur tournament in the country (only the Western Amateur has run longer).

Steve Cartano of Crofton and Kirk Lombardi of Norbeck, last year's respective winner and runnerup, are now both professionals. Richard Holland, the 1988 champion, is entered along with other top area amateurs.
