First baseman Andrés Galarraga, who spent his most memorable years with the Colorado Rockies and Atlanta Braves, was famous for walloping some of the hardest-hit home runs anybody's ever seen. He was at least as well-known, however, for being a nice guy. I don't think anyone has ever been happier to play baseball than The Big Cat, and this gratitude was apparent to everyone around him, from every last teammate to every last fan who held out a marker and a Sharpie to ask for an autograph. The guy radiated pure positivity in every direction.
