Marshall Renfroe was a left-hander who pitched for seven different major league organizations during the 1950s and early 1960s. He made his only big league appearance in a late season start for the San Francisco Giants against the St. Louis Cardinals on September 27, 1959, and gave up six runs in two innings but was not involved in the decision.
Marshall was a veteran of the Korean War, and had a younger brother, Dalton, who was a minor league catcher for eight years in the Washington Senators organization. Marshall was originally sent from the Crestview Braves of the Alabama-Florida League to the Philadelphia Phillies in an unknown transaction in June of 1954. He would spend six years climbing up the minor league ladder before his one-night stand with the San Francisco Giants.
Renfroe did not have a winning year until the 1958 season, pitching for the Danville Leafs of the class B Carolina League, going 12-11 with a 3.62 ERA while pitching 204 innings. He also had his second-best season (in terms of record), going 8-8 with a 3.54 ERA in 168 innings for the Phoenix Giants of the Pacific Coast League before his late-season fiasco in September of '59.
Marshall would spend three more seasons in baseball, all in the minors, finishing out his nine-season run in 1962 with a split season between Charlotte and Syracuse. He finished with a 60-88 record and a 3.99 ERA while pitching 1,131 innings.
Renfroe died tragically on December 10, 1970, in Pensacola, FL. The 34-year-old former pitcher was driving home from his job as a welder for Westinghouse when he stopped on a bridge to come to the aid of a stalled vehicle, and was hit by a gas truck.
