The 6-foot-1, 180-pound right-handed Seixas was an attacker who won more on determination and conditioning than on outstanding form. His volleying was exceptional, and he had an excellent match temperament, but a thrashing topspin forehand and sliced backhand were utilitarian.
Seixas was inducted into the International Tennis Hall of Fame in 1971.

A first rate athlete who considered himself “a frustrated baseball player,” Vic Seixas was an enduringly successful tennis player who made the most of himself in that venture. Seixas competed at the U.S. Championships at Forest Hills no fewer than 28 times from 1940 to 1969, setting a record in the process. On his last appearance he was 46 years old. Seixas, a relentless attacking player who packaged the serve skillfully with the volley, won Wimbledon at 29, took the championship of his country the following year, and was a prime contributor to the U.S. Davis Cup triumph of 1954.
