I guess my first favorite was Tom Seaver. It was 1971 on Long Island and everyone (with few exceptions) were Mets fans, and Tom Seaver was the most coveted baseball card. But I think the first guy I chose as a favorite, rather than picking it up from my peers, was Rusty Staub. I had to think for a while to come up with the first player I disliked, but it was probably Pete Rose, after his 1973 NLCS fight with Bud Harrelson.
