Game 1 of the ALDS Blue Jays Game this past Thursday was set to begin at either 3:37 p.m. and 4:07 p.m. (depending on who won the Yankees-Astros wildcard game). Why were there two start times?
Likely, the Houston Texans game Thursday night was the reason. That game stated at 8:25 ET, and while baseball games usually take three hours or so, most likely they wanted a bit of extra time to ensure fans can watch both games.
The Astros also had a game that night. A friend of mine has just made me aware of this fact. Blue Jays v Rangers would start at 3:37 and the Astros v Royals had a 7:37 start. This is more likely to be the answer. Overlapping MLB games (for teams) in the same state during playoffs is likely what they were trying to avoid.
Still waiting to hear from mlb though.
Thanks for your help.
