On March 25, 1920 while at bat in the top of the first inning during an exhibition game against the Brooklyn Robins, Fewster was struck in the temple by a pitch from Robins right-hander Jeff Pfeffer knocking him unconscious for approximately ten minutes. Fewster suffered a fractured skull and concussion which was complicated by internal hemorrhaging. He temporarily lost his ability to speak and underwent an operation at Johns Hopkins Hospital on March 31 to remove skull fragments and a blood clot, and to have a silver plate placed in to his skull. He rejoined the team on July 5 of that year and appeared in 21 games. [2]
Fewster is perhaps best known for being a part of one of the most famous flubs in baseball history, the "three men on third" incident that occurred during the 1926 season. Fewster was on first and future Hall of Famer Dazzy Vance was on second when teammate Babe Herman hit a long ball and began racing around the bases. As Herman rounded second, the third base coach yelled at him to go back, since Fewster had not yet passed third. Vance, having rounded third, misunderstood and thought the instructions to reverse course were for him. Thus, Vance returned to third at the same time Fewster arrived there. Meanwhile, Herman ignored the instruction to go back and also arrived at third at the same time. The third baseman tagged out Herman and Fewster; Vance was declared safe by rule.[3]
