That Astros - Brewers matchup would also be the gypsy World Series as the Brewers played in the AL West from 1969 - 1971 (in '69 as the Seattle Pilots), and then as the only central time zone team in the AL East from 1972-1993 (Washington's move to Arlington, Texas prompted that switch), then to the AL Central from 1994-1997 following the realignment of leagues into three divisions, and since 1998 out of the NL Central Houston, meanwhile, has migrated from the NL West (1969-1993) to the NL Central (1994-2012) and now to the AL West (2013 - ), not to mention having existed in just the plain old NL from 1962-1968 Either NL team winning it all this year would up the number of different champions over the last 20 seasons in MLB to 13 as the Dodgers last win was 1988 and the Brewers last won ... never. Obviously an AL win keeps that ticker at 12 as both the Astros and Red Sox have won recently and while the Marlins 1997 WS title 'falls out' of the 20-year window with the conclusion of this year's post-season, their 2003 WS win keeps them on the list so no reduction there. 21 different franchises have played in a WS during that same 20 year window*, a number which will go up by one if the Brewers prevail this week. Remaining unchanged this year is the number of franchises, three, who have failed to at least reach an LCS since 1999. Oddly all are from the NL: - Cincy, whose last NLCS appearance was getting swept in four straight by the eventual WS winning Braves in 1995 - Pittsburgh, whose most recent NLCS memory is that of Sid Bream sliding into home with the winning run for the 1992 Braves - and finally Montreal/Washington whose last -- actually ONLY -- LCS experience was losing to a Rick Monday Game 5/9th inning HR in 1981. In the bottom of that 9th Jerry White grounded out with Gary Carter and Larry Parrish on base to end the game (2-1 Dodgers). As the Nats they've famously lost four times -- 3-2 (2012) 3-1 (2014) 3-2 (2016) and 3-2 (2017) -- in the round just prior to the NLCS (moment of silence please ... OK, that's enough) The NFL, btw, has also had 12 different champions over that same 20 year span, but fewer finalists (20 vs 21/22 in MLB) and currently has nine different franchises on the outside looking in at the conference championship round over the most recent two decades: Buffalo, Miami, Cincy (tough sports town), Cleveland, Houston, Kansas City, Dallas, DC, and Detroit But the salary cap promotes parity!!! -- Yeah, no it doesn't. * not MIN, BAL, TOR, SEA, OAK on the AL side, nor CIN, WAS/MON, PIT, or MIL from the NL
