How kind of the MLB!
For your planning purposes, the MLB has released its 2013 Postseason schedule.
If the Tigers win the AL Central, their playoff run will begin on Friday, October 4th.
Should the Tigers advance to the AL Championship Series, the defense of their title would begin on Saturday, October 12th.
The 2013 World Series will begin on Wednesday, October 23rd ... and just as a reminder, the AL team has home field advantage. So, if the Tigers make it to the Series, games 1 and 2 will be at Comerica Park.
Exact game times will be announced at a later date.
Buster Olney has expressed some reservations about the schedule -- read his thought here.
