Since 2004, BBM has included a subset featuring people throwing out the first pitch at ballgames in the 2nd Version set. A couple of times, the person in question is a former player (Tetsuharu Kawakami, Akira Ohgi, Jim Paciorek) but usually they are a celebrity in some other walk of life than baseball - sumo wrestler, model, actor, politican, etc.
It turns out that a couple of the members of the Japanese Winter Olympic team currently competing in Vancouver have appeared in these subsets: speed skater Tomomi Okazaki and curler Mari Motohashi. Here are their cards from the 2006 and 2009 2nd Version sets (#761 and #804 respectively):
In addition, figure skater Shizuka Arakawa, a 2006 Winter Olympian, also appeared in the 2006 2nd Version set. Here's her card (#760):
