John Stamato, a stocky, steady golfer from Crofton, led the way with a three-over-par 75 to win the medal in the sixth annual Maryland Junior Open golf tournament at Hobbit's Glen in Columbia yesterday.

Stamato was declared the medalist after matching cards with William Fumai of Fort Meade, who shot the same score. He was more spectacular than Stamato but lacked the latter's steadiness.

Stamato and Fumai, both 17, were playing in the championship for 16 and 17 year olds. The medal for boys 14-15 was won by Pat Staveley, 15-year-old brother of Eisenhower pro Brian Staveley, with a 76 after matching cards with Manor's Jim Estes.

A field of 89 teed off under the leadership of 77-year-old Frank Emmet, who has been commissioner of junior golf in this area for 52 years.

Stamato had 13 pars and only one birdie, on the par-4 third hole. Fumai had three birdies, which were offset by four bogeys and a double bogey.

Stamato won the junior qualifying tournament in Baltimore last week and is headed for the USGA Junior in Hilton Head, S.C., next month. He is a long hitter, but his putting betrayed him as he missed two three-footers and one six-footer that would have given him an even better score.

On the other hand, Fumai's short game saved him on several holes and his putter saved him more strokes.

Staveley birdied the par-5, second hole from six feet and the 15th, a par 3, when he made an eight-footer. Estes, 14, also birdied the par-5 second hole when he chipped within two feet of the cup.
