In 1909 Jack Hobens hosted the US. Open, played at Englewood Golf Club where he was the professional. It was the practice during the week of the US. Open, for the professionals to take part in competitions organised by the host Club. On Tuesday Hobens won the mixed foursome event partnering Miss Julia R.

In the qualifying rounds for the 1913 US Open at Brookline, Jack partnered Ted Ray and the New York Times reported that when they both launched towering tee shots over and past the elbow of the dogleg on Polo Field the crowd erupted in appreciation. The two men walked off down the first fairway trailed by the largest-gallery of the day - over a thousand people including the writer Bernard Darwin.

On 17th January 1916, Rodman Wanamaker, a keen amateur golfer and heir to the Wanamaker department store fortune, held a meeting at the Taplow Club in New York City with a number of prominent professionals including Jack Hobens, for the purpose of forming the Professional Golfers Association of America. Their aim was to advance the standing of the club professional, caddies and greenkeepers in the United States.

Jack was elected Vice President of the first PGA Executive Committee. He was also one of three golf professionals who wrote the PGA's first constitution and by-laws. Wanamakers who incidentally were supplied with golf clubs by Ben Sayers & Son Ltd, sponsored the first PGA Championship in 1916 when Jack Hobens reached the last sixteen. Cornishman Jim Barnes defeated the former St Andrews caddie, Jock Hutchison by one hole, to lift the Wanamaker Trophy.
