Thomas Aaron Shearn (born August 28, 1977) is a former Major League Baseballpitcher. Shearn, who spent 11 years in the minor leagues, made his big league debut for the Cincinnati Reds on August 26, 2007, in a game in which he started for the Reds against the Florida Marlins. Before being called up, Shearn was living out of the groundskeeper's trailer at the stadium of the Reds' Louisville affiliate. Shearn had driven in his trailer from Louisville, Kentucky, to get to the game, as he was supposed to start that day for the Reds' AAA affiliate, the Louisville Bats. He made two more starts for the Reds in September, the best one coming in a 7-0 win over the Mets on September 5, 2007. In that game he threw six scoreless innings, striking out three and surrendering three hits. Shearn is famously quoted as saying, "Tom Shearn is only one man".
