This is a question that came up in my Facebook feed from some unknown source. I don't answer these things because they just lead to spam, but I'm okay with repurposing the question. How many Hall-of-Famers played in the first game you saw in person, and who were they? For me it was Johnny Bench and Tony Perez. August 4, 1971, Reds vs. Mets at Shea. Pete Rose also played in that game. Tom Seaver and Nolan Ryan were 1971 Mets, but neither appeared in the game that day. (Gary Gentry started for the Mets.) Joe Morgan didn't get into that game either, primarily because he was still a Houston Astro.
