Bartolo Colon arrives in camp as a member of an endangered species. It was his sixth season before he became an Expo (thank you, Omar Minaya), but he has a chance to be the last remaining one. Below I rank the recently retired, the hinted at retirement (Livan is apparently just finalizing a deal to become an instructor with the Nats), the all-but-retired (sorry, Miguel Batista), and the still active. I rank them by their most recent game, but obviously that's a matter of luck to many of the remaining guys. But if they all retired today, Luis Ayala would be our winner. Some still nominally active guys, though, can still pass some officially retired guys with a single appearance. Colon is far from the youngest (see Izutris, Maicer), but he is the only one with a contract for 2015. 19 =#BFBF00][crossout]Vladimir Guerrero[/crossout], of 39 years, 7 days old.

Two other notes: 1) The proliferation of Latin American ballplayers on this list is a nice reminder what a great job this organization did scouting Latin America. They lost their fain base because they couldn't keep anybody after they reached free agency, but the team stayed viable on the field (if not marketable) by always reloading from their largely Latin American prospect base. 2) How do you like Val Pascucci, staying in this little game so indefitagably. His entire career consists of 32 games with the 2004 Expos and 10 games with the 2011 Mets. He might have pulled off a stealth victory with a little luck.
