"While a fully contained bubble similar to the NBA setup at the Walt Disney World Resort in Florida would be difficult for MLB to replicate, a multicity format that replicates the NHL's Toronto and Edmonton hubs has gained traction," reports ESPN's Jeff Passan. "Because of MLB's expansion to 16 playoff teams, the league would need at least three hubs to complete its wild-card round before shrinking to a two-hub format for the division series. The league championship series and World Series could be held at one or two stadiums. Remaining in one metropolitan area would allow teams to avoid air travel and perhaps remain at a single hotel for the entire postseason, which is scheduled to begin Sept. 27."
