Jeff Osberg of Pine Valley became only the second player in history to complete the Golf Association of Philadelphia career Grand Slam, firing a 4-under-par 68 to win the GAP Middle-Amateur Championship at LedgeRock Golf Club.
Chris Lange Sr. of Overbrook was the first to complete the career Grand Slam, which consists of the Mid-Am, the BMW Philadelphia Amateur, the Philadelphia Open and the Patterson Cup.
Osberg, 36, bogeyed the 10th hole and trailed first-round co-leader Andrew Mason by four strokes before finishing in 3-under with birdies at the 12th, 13th and 16th holes. He also got up and down for par from 67 yards out on No. 17, sinking a 5-foot putt for the save.
Osberg finished with a 36-hole score of 5-under 139, two strokes ahead of former champion Matt Mattare of Saucon Valley, who closed with a 71. Mason, of Huntingdon Valley, and the other first-round co-leader, Jason Wilson of Olde Homestead, tied for third at 142.
