Gordon Vincent Sundin (October 10, 1937 – May 2, 2016) was an American baseball player. He was a right-handed pitcher whose professional career lasted for six seasons (1955–1959; 1961), but who made only one appearance in Major League Baseball — failing to record an out — for the 1956 Baltimore Orioles. Sundin batted right-handed, stood 6 feet 4 inches (1.93 m) tall, and weighed 215 pounds (98 kg). Sundin's catcher for that game was Tom Gastall, who entered the game with Sundin in the middle of the eighth. The next day, Gastall was killed in a plane crash.
