I like to think of potential matchups in terms of which prominent player's legacy the two teams most fully share. Baltimore-Cincy: That would be the All-Frank Robinson Series. Atlanta-Texas: The All-Jeff Burroughs Series? ATL-BAL: Davey Johnson ATL-DET: Darrell Evans ATL-OAK: Tim Hudson ATL-TEX: Jeff Burroughs (or Kevin Millwood) ATL-MFY: Who Gives A Crap CIN-BAL: Frank Robinson CIN-DET: Sam Crawford (historical); Dmitri Young (modern) CIN-OAK: Scott Hatteberg (although Joe Morgan spent 1984 in Oakland) CIN-TEX: Buddy Bell CIN-MFY: Ken Griffey Sr (because I refuse to give it to Paul O'Neill) STL-BAL: Chuck Diering or Jim Dwyer STL-DET: Placido Polanco STL-OAK: Mark McGwire STL-TEX: Luis Alicea? Todd Zeile? Darrell Porter? (the least impressive group) STL-MFY: Enos Slaughter or Lindy McDaniel (long histories there) SF-BAL: Stu Miller SF-DET: incredibly, Darrell Evans again SF-OAK: Vida Blue (or Barry Zito, if you prefer) SF-TEX: Will Clark or Gaylord Perry SF-MFY: Dave Righetti, when you include his coaching career out there WAS-BAL: Davey Johnson again WAS-DET: Pudge Rodriguez WAS-OAK: Matt Stairs? WAS-TEX: Pudge Rodriguez again (although there's obviously Washington --> Texas old time history there) WAS-MFY: Nick Johnson Only included current iteration of the Nats, although it's not all that impressive. edit: Changed WAS-BAL to Davey.
