The Maple Leafs have done something similar once already this baseball post-season. The end of the Blue Jays series-clinching win against the New York Yankees, was shown at Scotiabank on Wednesday, with much of hockey sticking around to cheer on Canada's team.
Game 1 of the ALCS starts at 8 pm ET/5pm PT on Sunday night on FOX. With the Leafs-Red Wings being moved up to 2pm, that should give fans plenty of time to watch three periods and have a quick break before switching to a baseball mindset.
