"Selby is God" fans While playing minor league baseball for the Pawtucket Red Sox in 1996, during an away game in Columbus, Ohio, Selby was introduced to three Ohio State University students (and Cleveland Indians fans) who became very vocal fans. Two days later, Selby was called up to the parent Boston club, playing in Cleveland, and he had a base hit that Friday evening against Cleveland closer José Mesa. The three fans made the trip that weekend and debuted a large cardboard sign that read, merely, "Selby is God." (The sign is an homage to a previous "Bernie is God" sign that honored Cowboy QB (and ex-Cleveland Browns legend) Bernie Kosar.) The "Selby is God" fans received some notoriety after Selby's grand slam off Rivera in 2002, appearing in The Plain Dealer and on television. Nicknaming Travis Hafner Selby is also known for bestowing Cleveland Indians DH Travis Hafner with his nickname, "Pronk". Selby explained the nickname to the Buffalo News: Texas came to town in 2002 and I was with [former Indian] Lee Stevens on the bench saying, 'This dude is unbelievable. He's a real project.' He was hitting the ball everywhere. We got him the next spring and we called him 'Project'
