He was the son of Peter Wynn, a ploughman, whose family home was situated at Sheriffhall three miles south of North Berwick, Scotland.

Wynne earned his professional ticket on the West Links at North Berwick in 1893 and was one of the original members of the PGA.

He won three professional tournaments: at Crawley in 1901; Troon in 1904; and the Midland Open in 1907, the latter being a qualifying event for the News of The World PGA Match Play tournament which was held at Sunningdale Golf Club, Sunningdale, in October 1907.

The great English player, Harry Vardon, won the Championship for the second time, a stroke ahead of Willie Park, Jr., the 1887 and 1889 winner.

[6] Wynne finished in a tie for tenth place with James Braid with rounds of 83-79-81-78=321.
