Medalist Joe Stamato of Crofton continued his steady progress in the Maryland Junior Open in this hot, sticky day at Hobbit's Glen with two victories to reach the semifinals in the championship flight.

Winners will be crowned Wednesday after two more rounds in both the championship (16 and 17-year-olds) and the 14-16 age group.

Stamato beat Curt Urweider of Congressional, 4 and 3, in the morning and then disposed of Mark Kim, Severna Park, 3 and 2, in the afternoon.

Bill Fumai, of Fort Meade, who lost the medal Monday to Stamato on a match of cards, also gained the semifinals with a 2-and-1 victory over Marlboro's Steve Elkins and a 1-up struggle over Robert Dolan of Montgomery Village.

The 14-15 group saw the elimination of medalist Pat Staveley, of Crofton, who lost to Michael Duffy, of Mount St. Joseph's, on the 20th hole. Staveley's carelessness caused him to lose the match.He lost the 10th hole when he practiced with range balls while he waited for his second shot. Duffy evened the match on the 18th and won on the 20th when he sank a 40-foot putt for a par.

Jim Estes of Manor, who lost the medal to Staveley on a match of cards, won his two matches today, over Cobby Webb, Greencastle, 3 and 2, and Jamie Childs, Naval Academy, 5 and 4. Childs was bothered by a blister on his right heel.
