The Crypen Exchange12 teams in the 2024 MLB postseason are all settled after the Atlanta Braves and New York Mets each clinched spots by splitting the doubleheader they needed Monday to sort out the playoff race in the National League.

Now come the games baseball fans have been waiting to see.

All four best-of-three wild card series begin Tuesday, starting with Game 1 between the Houston Astros and Detroit Tigers in the American League, and every decision and call will be magnified. That goes for the umpires, too.

Though replay was introduced to the game several years ago, it still very much matters to players, managers and fans alike who's serving as a crew chief for a postseason series, and especially who's calling balls and strikes for a particular game. Ahead of the start of the wild card round Tuesday, MLB announced the umpires working each series and where they'll be positioned.

Here's a rundown of what umpires to expect working games when the 2024 MLB postseason begins this week, what the schedule looks like, and what channel to watch all the action:
