Each week leading up to the 107th U.S. Open, the Post-Gazette will chronicle a past major moment or some historical aspect at Oakmont Country Club.

Bobby Jones came to the 1927 U.S. Open at Oakmont Country Club as something of an overwhelming favorite, even though he was an amateur. After all, he had two victories and two runner-up finishes in the previous four U.S. Open championships and had won the U.S. Amateur at Oakmont two years earlier.

But in the first U.S. Open played at Oakmont, Jones was no match for Tommy Armour, who birdied the final hole of regulation to force an 18-hole playoff with Henry Cooper the next day. Armour won the playoff, 76-79, for his first victory as a professional.

Armour, a native of Scotland, hit one of the most memorable shots in Oakmont history -- a 3-iron from 180 yards at the 18th that landed 10 feet from the pin. When Armour made the birdie putt, it forced a playoff with Cooper, who was watching from the clubhouse porch.

"I was quoted as saying I hoped he would make it so that I can show him I can beat him the next day," Cooper said years later. "That was a lot of stuff. I was standing up there saying, 'Miss it ... miss it.' "
