Today we get a season finale like no other, and it is anything but regular.

In a first-of-its-kind simultaneous set of cliffhangers, every team with uncertain postseason possibilities began playing at 3 p.m. ET, leading up to a flurry of dramatic walk-offs or precious final outs.

You've got questions? So do all the contenders, especially the eight teams with important and unfinished business.

Explaining possible tiebreakers

The answers will come at us all at the same time.

It's #Game162 Day, and the Greatest Game Show On Earth started like a Triple Crown horse race, which is fitting, you know, because of the simultaneous "and they're off" first pitches out of the gates.

To help sort through all of this and celebrate the amazing slate, Commissioner Rob Manfred appeared on MLB Network to discuss the different scenarios and the excitement of the day.

"Just an unbelievable wrap-up to our season, teams playing meaningful games on the last day all at 3 o'clock, we think its going to be a really great afternoon for our fans," Manfred said.

And befitting the anticipation of today's action, Manfred took part in a virtual first-pitch interview, which was streamed live on MLB.com.
