[Gallery] MLB’s 15 Biggest One-Hit Wonders of All-Time

BOB HAMELIN, DH, ROYALS, 1994

George Brett retired in 1993 after a Hall of Fame career and was replaced by Hamelin. Much to everyone’s surprise, Hamelin outdid Brett himself by hitting .282/.388/.599 in 101 games and smacking 24 home runs. He easily won the Rookie of the Year award over another pretty good slugger named Manny Ramirez. But all Brett comparisons faded after that season. Hamelin struggled to reclaim his former glory and was even sent down to the minors to work on his swing. The Royals eventually gave up on him, and he was out of baseball by 1998 after just six major-league seasons.
