The 2020 major league season is about 20% done, which might feel strange given that the season isn’t quite two weeks old, but it’s just one of the many odds things about this year. We’re just three weeks from the trade deadline and the basic contours of who the contenders and the also-rans are has become clear in a shockingly small number of games. That shortened slate has also seen a number of key players go down with significant injuries. The threat of COVID-19 looms large over any discussion of missed time this season, but sadly, more familiar maladies will also take their toll — Justin Verlander is still weeks from a potential return from a right forearm strain, Shohei Ohtani likely won’t pitch again this season after leaving Sunday’s game with a forearm strain of his own, and Mike Soroka joined the list with a painful tear to his Achilles tendon Monday evening, ending his 2020 season before it had really begun. Even Max Scherzer exited Wednesday night’s action with a sore hamstring, though thankfully it appears minor.

How big a loss for the Braves was Soroka? With him still in the rotation, the ZiPS projection system had the Atlanta Braves with an 89.5% chance of making baseball’s expanded 16-team playoffs. Without Soroka, that number drops to 81.5%, nearly doubling the probability that Atlanta watches the playoffs from home. How does that eight percentage points rank among baseball’s stars? As I do every season, I asked ZiPS to re-project league standings with individual star players removed from their team’s rosters.

This isn’t a WAR ranking, which would be kind of boring. Teams whose playoff fortunes are most up in the air, especially those without sufficient depth, tend to be the ones that get in the most trouble when they lose a key player due to injury. The combination of good early results and deep rosters has left a few teams at the top of the food chain — the Braves, Dodgers, Athletics, Twins, and Yankees — without a single player in the top 25 in playoff leverage. That’s not to say that losing Mookie Betts or Cody Bellinger wouldn’t be a huge loss for the Dodgers, but the team has good backup options and it would take losing both to seriously change the team’s playoff odds.

With Wednesday night’s games in the books, here are the ZiPS-projected playoff probabilities for every team:

Our oddball 2020 season has featured a lot of strange sights and next week, we’ll get another one, when the Toronto Blue Jays stage their home opener (or at least, their first home game not played in another major league team’s park) in another country. Because of the COVID-19 pandemic and the shall we say mixed success the United States has had combating the spread of the virus, Canada refused to grant the exemptions needed for the Blue Jays to play their season in Toronto.

“Based on the best-available public health advice, we have concluded the cross-border travel required for MLB regular season play would not adequately protect Canadians’ health and safety,” Canada’s Minister of Immigration, Refugees and Citizenship said Saturday in a statement. “As a result, Canada will not be issuing a National Interest Exemption for the MLB’s regular season at this time.”

Canada’s statement seemingly leaves open the possibility that the Blue Jays could come home for a theoretical postseason series if the environment is more favorable. But that would be a few months away, so Toronto’s next home game will be played — or at least is scheduled to be played — in upstate New York rather than the Queen City. And when I say upstate New York, I mean upstate New York; we’re leaving behind the pizza, bagels, and pastrami of the city for beef on weck, grape pies, steamed hams, Buffalo’s eponymous chicken wings, and Sahlen Field, which is usually home to Toronto’s Triple-A affiliate and this year will host the migratory Jays.

If you’re a fan of the Chicago Cubs, it would not be surprising if you describe your feelings about Tyler Chatwood as some kind of frustrated exasperation. Able to survive in the mile-high environment of Coors Field despite occasionally spotty control and an inability to punch out batters, the Cubs expected that Chatwood would do even better in the friendly confines of Wrigley; the days when the wind is blowing out in Chicago weren’t supposed to be much of a problem for a pitcher who largely avoided giving up big home run totals in Colorado. On that assumption, the Cubs signed Chatwood to a three-year, $38 million contract before the 2018 season.

Suffice it to say, 2018 did not go as anyone predicted or hoped, except maybe Cardinals fans. Chatwood’s season started deceptively well, with a 2.83 ERA in April, but 22 walks in 28 2/3 innings suggested trouble. After throwing seven shutout innings against the Brewers on April 29 of that year, he went three months without a single quality start and walked at least two batters in every game. The team’s acquisition of Cole Hamels resulted in Chatwood’s exile to the bullpen, where he was little-used until injuring his hip in an emergency start as a replacement for Mike Montgomery. A non-factor in the pennant race that September, Chatwood’s 103 2/3 innings of work for the season was still enough time to amass a league-leading 95 walks.

2019 went better, but Chatwood’s role was mostly that of a fill-in starter and low-leverage reliever and mop-up guy. His 4.28 FIP in relief didn’t send a tingle down anyone’s spine, and his decision to largely abandon his secondary stuff didn’t seem like a likely ticket back to the rotation. However in the second half, he did tinker with his cutter’s grip after recognizing an issue with the pitch, which he had largely moved away from in 2019:

Dan Szymborski: July.

Dan Szymborski: More seriously, he’s been a lot of fun so far, but the threshold for me greatly changing my view of a player in a positive direction is quite high when just the season before, they struggled against Double-A pitchers. At least relative to how prospects typically fare.

Dan Szymborski: It’s tricky. We do try to assign framing credit to the pitcher and hitter. And there’s stuff like passed balls, errors, stolen bases, etc.

Ted Williams isn’t the typical beneficiary of a trip in the ZiPS time machine. After all, anyone who has the slightest interest in baseball — and many who don’t — know his name, even if they aren’t familiar with every last one of his accomplishments. Williams typified the cerebral, scientific hitter in the same way that Babe Ruth created the archetype of the larger-than-life slugger. The mercurial Ruth likely would have had considerably more trouble adapting to today’s game, but I’m of the opinion that the Splendid Splinter would actually thrive in a world where offense is looked at more as science than myth made true. Perhaps the best modern comparison for Williams is Joey Votto if the latter somehow got a hold of a genie’s lamp.

The list of Williams’ accomplishments is far too lengthy to run down in complete fashion, so we’ll settle for a sampling. He’s first all-time in on-base percentage and second in slugging percentage. He’s the most recent player to hit .400, and a two-time Triple Crown winnner. Ted finished with a .344 batting average, 521 homers, 2,654 hits, and enough black ink in his stats that he could have started his own newspaper.

But Williams’ career was also marked by long absences from the game. He was drafted after Pearl Harbor, initially receiving a deferment because he was his mother’s sole support. He played through the 1942 season, but enlisted in the Navy reserve after its conclusion and served for the next three years.

In terms of baseball, those were prime seasons of his career lost. The 1943-1945 stretch represented his age-24 through age-26 seasons, years when a lot of Hall of Famers turn in some of their most eye-popping campaigns. Taking a look at the list of Hall of Fame hitters through those ages sorted by WAR, there are some truly gigantic numbers involved:

I’m a big liar, or at least I am thanks to Major League Baseball. Last week, after the longest offseason in modern baseball history, I posted the Final ZiPS 2020 Projected Standings. It turns out, however, that these weren’t quite as final as we hoped. Last Thursday, MLB took the step — unprecedented in major sports, at least in my memory banks — of changing the league’s playoff structure the day the season started. The already-bloated 10-team playoff format became an engorged 16-team one. In are four mediocre teams; out is most of the advantage division winners get for being the best in their divisions.

I’m still hopeful this is solely a 2020 issue; the agreement between MLB and the Players Association was only for this year. Baseball’s regular season is the most important in major team sports, after all. Plus, it’s in the interests of the players to avoid further decoupling championships from team quality, as that would inevitably create a further drag on salaries. Assuming 2021 reverts to normal, it still leaves the question of 2020 projections. After a three-day weekend immured in my Fortress of Statitude, I’ve reconfigured ZiPS for the umpteenth and hopefully last time, and present the final, actually official 2020 projected standings. All the commentary in my original article still stands, but now the numbers are quite different.

Warning: There are lots of charts coming.

Let’s start with new start-of-season projections. For these standings, ZiPS knows nothing about what has happened so far this season, whether it’s wins, losses, player stats, or injuries. Whatever it knew last Wednesday, it still knows.

We made it! It took a four-month journey through a still-raging pandemic and some still-burning baseball economic issues, but Opening Day of the weirdest season we’re likely to see in our lifetimes is here. The 2020 season is not a marathon, but a sprint, so we’re already in the home stretch. We’re not starting at square one, of course; if this were Monopoly, the bank would be out of hotels and everyone playing the game would hate each other, especially that jerk who has Boardwalk and Park Place.

Projecting such a season presents some unique challenges a prognosticator doesn’t normally face. It’s not projecting the individual players’ production that’s the problem so much as all the stuff around it. How many players will miss time due to the league’s COVID-19 protocols? How do we adjust for injuries when teams will play just 37% of the games, but players’ recovery from hamstring and elbow woes won’t be similarly prorated? Will top prospect talent have the same short-term upside when they’re riding the bench or practicing at their team’s alternate site that they would if they were playing actual games in the minors? How will the strange, crowdless games and the stresses of keeping up social distancing guidelines affect play?

No, I’m actually asking! I can make educated guesses that I hope aren’t preposterous, but I don’t actually know the answers to these questions. For someone who models stuff, it’s a maddening situation. But it’s a challenge I can’t avoid given that projecting stuff is, well, a big part of my job! But you’re not here to commiserate with me, humor my self-indulgent wordsmithing, or dig out where I make a reference to the Battle of Actium in 31 BC, so let’s go straight to the final projected standings.

One of the ways that the baseball of yesteryear was different from baseball today was the importance of batting average. With a pitching philosophy that envisioned lots and lots of balls being hit into play and no gauntlet of modern relief pitchers to face, far more at-bats ended with a ball being handled by a defensive player. In 2019, 63% of plate appearances ended with a ball being hit into play. In 1919, that figure was 81%. With half as many fieldable balls, it’s hardly a shock that league batting averages have declined. The effect would be even larger, too, but batting average on balls hit into play was higher in 2019 (.298) than in 1919 (.282).

Hitting .400 was never an easy feat, but it wasn’t some wild, once-in-a-lifetime occurrence when it did happen. The .400 mark has been eclipsed 34 times in major league history, give or take (the number varies depending on just what you consider a major league team in the wild world of 1870s baseball). Ted Williams hit .406 in 1941 and that was it, the last time a major leaguer hit .400 over a season. It’s more than just the lower league batting averages. Baseball’s .252 batting average in 2019 was still higher than in 17 seasons before 1941. Baseball has trended in a more competitive direction and as a league becomes more competitive, you generally expect the differences between players to shrink. That’s true for batting average, too. Just look at the simplest measure of dispersion, standard deviation:

The standard deviation has gotten smaller as time has progressed. Using this simple method, Ted Williams’s .406 in 1941 was 4.46 standard deviations better than the mean batting average of .262 (z-score). A z-score of 4.46 in 2019 only represents a .370 batting average. Nobody’s hit that mark recently, either, but .370 certainly doesn’t feel like anywhere near the same hurdle.

Since it’s the obvious next question, here are the best batting averages by Z-Score. Again, there are more robust ways to look at this, but we’re scrawling on envelope-backs, not landing astronauts on the moon:

Earlier today, Paul Sporer took you through baseball’s 16th-to-30th ranked rotations. Now, we get to the good stuff.

What is a starting pitcher? While baseball’s rules have been relatively stable throughout the game’s history, being a starter in 2020 means something very different than it did in 1870, 1920, or even 1970. A starting pitcher in the 1800s was frequently the pitcher in any given game. When Hall of Fame pitcher (and later, Twitter superstar), Old Hoss Radbourn pitched for the 1884 Providence Grays, he started 75 of the team’s 114 games, completing 73 of them.

Being a starter meant something else in the early 20th century. They were still workhorses expected to finish a large percentage of their games, but they were part of a pitching staff, not lone wolves. Jack Chesbro was the last 50-game starter, in 1904. Four-man rotations became the standard and league leaders in games-started ranged from the high 30s to the low 40s. The only exception was one last surge in the early 70s from rubber-armed knuckleballers Wilbur Wood and Phil Niekro. The four-man rotation then became a five-man affair, and it’s now been 33 years since a pitcher started 40 games (Charlie Hough, 1987) and 40 years since one threw 300 innings (Steve Carlton, 1980).
