This debate continued for several years, and became more intense as the Cubs returned to competitiveness during the early 1980s. When the Cubs won the National League Eastern Division title in 1984, then-commissioner Bowie Kuhn announced that the Cubs would lose home field advantage should they advance to the World Series (home field advantage alternated between the champions of the National League and American League until 2003), since by this time nearly all World Series games were played at night in the Eastern and Central time zones. After winning their two scheduled home (day) games in the National League Championship Series, the Cubs lost all three games in San Diego, so Kuhn's threat became moot. But the following year, new commissioner Peter Ueberroth announced that because Wrigley Field had no lights, the Cubs would have to play "all" future postseason games at another ballpark, likely Comiskey Park, Soldier Field, or possibly even St. Louis' Busch Stadium, or Milwaukee County Stadium. The Cubs fell out of contention for the next several years, however, and the possibility of playing post-season "home" games in other cities did not arise.
