Smith was the head professional at Nassau Country Club in
Glen Cove, New York, from 1901 through 1909.
James Maiden, who would forge a successful golf career of his own, served as assistant professional under Smith at Nassau. Smith's
1906 U.S. Open victory came at the
Onwentsia Club in
Lake Forest, Illinois. His 72-hole score of 295 was the lowest at either the U.S. Open or the
British Open up to that time, and he won $300. The
1910 U.S. Open was played over the St. Martin's course at the
Philadelphia Cricket Club. Smith won a three-man playoff against American
John McDermott and another of his own brothers,
Macdonald Smith. Alex Smith played in eighteen U.S. Opens in total and accumulated eleven top ten placings. Smith, who partnered with C. A. Dunning in the 1905
Metropolitan Open four-ball tournament held on 16 September 1905 at Fox Hills Golf Club on
Staten Island, tied for first place with
George Low and
Fred Herreshoff with a score of 71. A playoff wasn't held due to the fact that Smith was also competing in the medal competition which he won from
Willie Anderson. Smith also won the
Western Open twice and the
Metropolitan Open four times. He was the head professional at the
Westchester Country Club in Rye, New York. ==Personal life==
