Joe Charboneau

A rookie sensation who burned bright before fading fast, Charboneau captured the 1980 American League Rookie of the Year after posting a stellar .289 average with 23 home runs for Cleveland. His 118 OPS+ that season suggested a potentially elite bat, but a steep decline followed. Over his three-year career, he hit just .266 with an unremarkable 100 OPS+, making him a cautionary tale about sustainability. Charboneau remains remembered more for that single transcendent rookie campaign than for any lasting impact.
