While we don’t yet know for sure whether there will be a 2020 baseball season, any resumption of baseball will likely involve a year that looks like nothing that has come before. Among the many proposals out there, ranging from the tinkering to the radical, is one to eliminate the traditional AL/NL league structure for this year in the so-called Arizona-Florida plan. Teams would play at their Cactus and Grapefruit League spring training facilities (along with Chase Field, Tropicana Field, and Marlins Park), facing off against the teams in that state. Basing teams in the spring training leagues has the benefit of working with existing team facilities, and, as Ben Clemens wrote for the site earlier today, addresses some of the broadcast and climate difficulties, though of course it is as dependent on the widespread availability of testing as the Arizona plan.

Assuming that we go with the highly unusual Cactus/Grapefruit season, the races will naturally look very different than we’re accustomed to. The spring training league assignments adhere more generally to an east/west alignment than an AL/NL one, so many of the traditional rivalries would take on a very different character in 2020.

With a little bit of work, I was able to realign ZiPS to project the outcome of these new league races. Naturally, there’s a little bit of speculation required to formalize this strange new 2020 MLB. I’ve engaged in such speculation because, well, that’s my job!

For the new 2020, I’m assuming that both leagues use the designated hitter, as Bob reported. While the DH/Pitcher hitting battle still rages among baseball fans, in such an unusual season, when pitchers are already having a very odd training schedule, there’s a lot to recommend a universal DH rule, at least temporarily. Without pre-existing divisions, I’m also going to assume that we’d be seeing division-less leagues in 2020. Also, no interleague play, given that the whole idea of spring training leagues is to avoid lots of travel.

Any postseason under this arrangement is unlikely to be smaller than the current slate of ten teams, so I’ve told ZiPS to project standings based on 15-team leagues with three teams receiving one-game “byes” while two Wild Card teams play a one-game, winner-take-all matchup. From a structural standpoint, this allows a postseason of similar character as the typical postseason.

How many games will be played is still unknown, so I’m assuming a 112-game season. With 15 teams in a league, this enables each team to play every other team four times at home and four times on the road.

So, how do the projections look?

This realignment is quite beneficial for the Los Angeles Dodgers. Even with 14 “divisional” opponents instead of four, the Dodgers still remain in a very strong position. In fact, it even improves somewhat, with the team projected with a 60% chance of leading the Cactus League in wins compared to 44% in the National League and a few of the NL Wild Card finishes becoming Cactus League byes. Perhaps it would serve as a small token of compensation for never getting to see Mookie Betts in Dodger Blue at Chavez Ravine?

Overall, the Cactus League looks like a middle-class one. The Dodgers are the only 2019 division winner in the league and only two other 2019 playoff teams, the Brewers and Athletics, would play in Arizona. Only the Mariners project to assume true doormat status in what looks to be a very competitive Cactus League. How do things look in Florida?

With five of six 2019 division winners and seven of the 10 playoff teams, the Grapefruit League is the more bifurcated of the two leagues. Whereas the Dodgers project to have a fairly clear path to dominance, the Yankees suddenly have a whole lot of competition beyond the Rays. There’s a very clear dropoff from the contenders to the slingshots, with the dividing line being drawn after the Red Sox (who aren’t as bad off, even without Sale, as some people imagine). I’m sure MLB would be happy about leaving the traditional Yankees/Red Sox rivalry intact, with the Yankees and Mets as compensation for some of the central division rivalries, like the Cubs and Cardinals, that would be split up.

So, who gets the most playoff benefit? Here are the teams ranked by their playoff probabilities, in percentage points:

2020 Playoff Probability Change Team Cactus/Grapefruit AL/NL Difference San Diego Padres 54.3% 45.7% 8.6% Oakland Athletics 60.8% 52.8% 8.0% Arizona Diamondbacks 31.0% 23.3% 7.7% Los Angeles Angels 29.4% 21.8% 7.6% Cleveland Indians 62.6% 56.2% 6.4% Chicago White Sox 30.7% 24.4% 6.3% Texas Rangers 9.5% 6.2% 3.2% Milwaukee Brewers 36.6% 33.8% 2.7% Cincinnati Reds 32.7% 29.9% 2.7% Chicago Cubs 45.6% 43.1% 2.5% Colorado Rockies 5.1% 3.1% 1.9% Los Angeles Dodgers 95.4% 93.8% 1.6% San Francisco Giants 2.9% 1.6% 1.3% Kansas City Royals 3.4% 2.2% 1.2% Seattle Mariners 0.2% 0.1% 0.1% Baltimore Orioles 0.0% 0.0% 0.0% Detroit Tigers 0.1% 0.2% -0.1% Miami Marlins 1.0% 1.4% -0.4% Toronto Blue Jays 3.0% 3.7% -0.7% Pittsburgh Pirates 1.7% 3.3% -1.6% New York Yankees 89.2% 92.0% -2.7% Boston Red Sox 19.7% 22.5% -2.8% Philadelphia Phillies 22.8% 27.7% -4.9% Tampa Bay Rays 64.7% 69.9% -5.2% New York Mets 26.1% 31.3% -5.2% Washington Nationals 58.5% 64.8% -6.4% Houston Astros 73.4% 79.9% -6.5% Atlanta Braves 59.0% 65.9% -6.8% Minnesota Twins 59.3% 68.2% -9.0% St. Louis Cardinals 21.6% 31.0% -9.5%

The west coast teams that are below the top-tier contenders see the largest benefit from this temporary realignment, with a lot of room to jockey for the prime playoff spots behind the Los Angeles Dodgers. The big losers here are the AL powerhouse teams, which mainly have to face off against each other while welcoming the world champion Nationals and the 97-win Braves.

But from another point-of-view, you can say all 30 teams are the big winners. A year with baseball is better than a year without it, and if a format like this allows there to actually be a season, I can’t imagine any baseball fan being against it.
