This is the fifth installment of this year’s Team Entropy series, my recurring look not only at the races for the remaining playoff spots but the potential for end-of-season chaos in the form of down-to-the-wire suspense and even tiebreakers. Ideally, we want more ties than the men’s department at Macy’s. If you’re new to this, please read the introduction here.

In the National League playoff picture, we’re down to two teams — the Dodgers (89-71) and Cardinals (87-73) — fighting for one spot, as the Rockies (90-70) clinched a postseason berth on Friday night by beating the Nationals for their eighth straight win. That said, neither the NL Central nor the NL West races have been decided, nor have the actual Wild Card game participants, leaving open the possibility that we could have multiple Game 163 tiebreakers on Monday. The dream scenario of needing a third tiebreaker game, in the event that the two NL West participants (the Dodgers and Rockies) finished tied with St. Louis, is off the table given the Cardinals’ back-to-back losses to the Brewers (93-67) and Cubs (94-66).

On Friday afternoon, I had the privilege of appearing on MLB Network’s MLB Now, where host Brian Kenny put the spotlight on Team Entropy at the top of the show and allowed me to talk through the various scenarios:

Pretty cool! Except that the Cardinals were busy getting pummeled by the Cubs as that happened — the show kept cutting away to the action — simplifying the picture somewhat. So here is what’s left…

The Cubs, who are hosting the Cardinals, and the Brewers, who are hosting the Tigers, can still finish in a tie after 162 games if Milwaukee can pick up a game this weekend. Either the Brew Crew goes 2-0 while the Cubs go 1-1, or 1-1 while the Cubs go 0-2. That would leave the two teams playing on Monday in Chicago (which won the season series 11-8) to determine which one wins the division, and which hosts the Wild Card game. As of Saturday morning, our playoff odds ties page shows a 25.9% chance of such an occurrence.

Likewise, the Rockies, who are hosting the Nationals, and the Dodgers, who are visiting the Giants, can finish tied if Los Angeles can pick up a game. The Dodgers, who won the season series 12-7, would host a tiebreaker game on Monday to determine the division winner, and second Wild Card team. Our ties page gives this game a 34.1% chance of happening.

Alternately, if the Cardinals win both of their remaining games and the Dodgers lose both of theirs, the two teams would be tied for the second Wild Card spot. They would play on Monday in St. Louis, which won the season series 4-3. This scenario can happen in tandem with an NL Central tie if the Brewers also split their remaining pair of games. The odds of a Wild Card tie are down to 2.4%, but that’s better than nothing, particularly with a second tiebreaker game also still an option.

With the Cubs and Cardinals playing at 1:05 pm Eastern, the Dodgers and Giants at 4:05, the Brewers and Tigers at 7:05 pm and the Rockies and Nationals at 8:10 pm, we have the whole day to savor the possibilities for chaos. Enjoy!
