I have to go over this again every few years. The Cubs are the only team remaining that has opened a new field, not an existing field, and have not won a World Series in it. I am not including the new fields that have recently opened like Comerica Park or Jacobs Field. My comment was for old timers and old parks.
You must be really young because the Pirates(Mazeroski's home run in 1960), Reds(The Big Red Machine in the 70's), Marlins in 1995, Braves during the Hank Aaron 1957 era and in 1995(their only World Series in the 90's), Mets in 1969(Miracle Mets) and 1986(Bill Buckner's boot) , Tigers in 1968 and 1984, Orioles(several times with the most memorable when they beat the World Champion Dodgers, Sandy Koufax, Don Drysdale and Claude Osteen in 1966, Twins with Jack Morris in 1991 and Indians in 1948 with Spahn and Sain and Pray for Rain, have all won in their previous ballparks.
Please look up your facts and get them straight before displaying your lack of knowledge of baseball lore.
