Checking out the 500-club for the first time in a long while: - 25 members now. When I first learned it there were four Four? That surprises me. I guess you're more than a couple of years older than me. I just looked it up, and the fifth player to hit his 500th home run was Willie Mays, on 09/13/1965. (The first four were Ruth, Foxx, Ott, and Williams.) By the time that I first started paying attention, in 1971, the list was up to nine, with the additions of Mantle, Mathews, Aaron, and Banks. During the 1971 season, Frank Robinson and Harmon Killebrew hit their 500ths, but I have no memory of being aware of it. I was a baseball nerd at a very young age. Not that I have a specific memory of Mays hitting his 500th, although I do remember when Denny McLain served up - and we do mean served up - #535 to Mantle so he'd pass Foxx. I also would have had trouble pegging the order of many of those guys, a thought which sent me into some research.

Biggest one since was the nearly 10 years after Schmidt and before Murray. Been a year and a half since the last new inductee and looks like it'll be at least a 4 year gap until the next one.
