For whatever reason, sometimes I am only able to find one card of certain players. To be considered a One-Card Wonder, a player must have been active since 1991 (when I started paying attention).JOE NELSON
Joe Nelson pitched in exactly three games for the Red Sox in 2004. And he did not really pitch well either, accumulating a 16.88 ERA, while walking three in 2 2/3 innings, but he did strike out five. So, it was not much of a surprise that he did not re-emerge in the majors until 2006 when he pitched in 43 games for the pitching-starved Royals. He then became a serviceable middle reliever for the Marlins and Rays in 2008 and 2009 respectively and returned to the Red Sox in 2010, for whom he once again flopped, pitching in eight games with an ERA above 9.00.
