Bill Mueller
The "Idiots" of 2004 arose out of the "Cowboy Up" team of 2003, a nickname derived from first baseman Kevin Millar's challenge to his teammates to show more determination. In addition to Millar, the team's offense was so deep that eventual 2003 batting champion Bill Mueller was 7th in the lineup behind sluggers Manny Ramírez and the newly acquired David Ortiz.
