Ooooooh...I didn't think of games played, but you're zooming in on the right statistic. You're close. There are pretty much 2 prongs to the common thing. You were close to one when you were noticing the birthplaces. The second has something to do with achievements over time. In fact, I'd have given you games played as a common feature, but I would have had to remove Vinny Castilla, and substituted Aurelio Rodriguez. When you put the 2 prongs together, you might get the commonality.
