What causes groups to reach the playoffs? This is without doubt one of the debates in baseball most ridden with standard knowledge, folksy tales, and grand assertions. Some declare that groups have to have playoff expertise. Others give attention to clutch efficiency, which normally coincides with regardless of the individual needs to argue. A typical argument, extra cloaked within the language of reasonableness, is that groups which might be extra reliant on house runs than different methods of scoring underperform within the postseason. There are myriad causes given for why some groups find yourself profitable October, and most of them can examined for accuracy primarily based on baseball historical past. I did a chunk final yr that checked out dozens of various staff variables, and many of the explanations meant bupkis.
That doesn’t essentially imply we throw our fingers within the air and simply assume groups are equally nearly as good as they’re within the common season and go along with that. There are important structural variations between postseason and regular-season play merely because of the variety of video games and the elevated variety of off-days. Common-season profitable share is without doubt one of the few good predictors of postseason success; projections do even higher. After I change the methodology within the ZiPS projections to focus extra on a staff’s frontline expertise and the precise matchups and fewer on necessary regular-season issues like depth, staff energy turns into considerably extra predictive of postseason success.
Top-of-the-line current examples of that is the Nationals in 2019. Regardless of the 13-win regular-season benefit of the Dodgers, ZiPS projected their NLDS as a coin flip on the energy of the Nats with the ability to stuff a lot of their staff’s worth into gamers who could be on the sphere. That was a projection that bought a variety of pushback, however in the long run, Washington received the World Collection, principally driving the highest of the rotation, just a few actually good hitters, and the 2 or three relievers that Dave Martinez might really belief.
As I’m an obsessive tinkerer, I’ve carried out extra work on the topic within the final yr. Utilizing the unique methodology, I discovered a slight benefit for groups that have been extra reliant on house runs to attain runs. After extra analysis, I’ve discovered that the homer-reliance benefit turns into an much more important indicator if you’re going towards elite pitchers. There’s one thing that makes intuitive sense there; one of the best pitchers are exhausting nuts to crack, and also you’re extra more likely to break them with just a few homers. Only one instance is Clayton Kershaw. His struggles within the playoffs are nicely famous, nevertheless it’s totally resulting from house run fee; his BABIP, strikeout, and stroll charges are almost equivalent to the common season. However it doesn’t matter what the logic is that if the information doesn’t match; the tendency for homer-reliant groups to overperform within the postseason traditionally almost doubles when taking a look at solely the video games by which the opposing beginning pitcher had a seasonal ERA+ of 125 or higher.
So, which groups get a postseason enhance from structural design? Let’s crunch some numbers! To get this, I took the doubtless postseason rosters for every of the 15 playoff-relevant groups remaining (I unnoticed the Giants, at 0.1% playoff chance) and used the regular-season mannequin to estimate their anticipated profitable share towards a .500 staff in a impartial park. Accidents are difficult at this level within the season, so educated guesses needed to be made about participant availability. For instance, the Braves get half of Charlie Morton, and the Rangers get 20% of Max Scherzer. It was necessary to maintain the roster design the identical for normal season and playoffs in order that we have been taking a look at how the groups are presently constructed, not who will get what pitcher again subsequent week (e.g. the Braves and Max Fried, who’s presently unavailable).

|Tampa Bay Rays
I then recalculated everybody’s energy utilizing the postseason mannequin and ranked them by the change from regular-season to postseason projection. Let’s really begin with the non-playoff groups, each as a result of I’m a merciless man and since it’s fascinating to see which groups might need precipitated havoc within the playoffs if that they had gotten there:
ZiPS Projections – Playoffs vs. Common Season (Eradicated Groups)
|San Diego Padres
|New York Yankees
|Los Angeles Angels
|San Francisco Giants
|New York Mets
|St. Louis Cardinals
|Chicago White Sox
|Boston Purple Sox
|Kansas Metropolis Royals
The Padres have been a little bit of a practice wreck due to their one-run and extra-inning performances, however they nonetheless had the front-end offensive expertise to make groups uncomfortable, if their last-gasp try and make the playoffs had succeeded. And whereas that is arguably the worst Yankees staff of the final 30 years, they nonetheless have Gerrit Cole and Aaron Decide, and even their mediocre hitters can nonetheless run right into a homer occasionally.

|Los Angeles Dodgers
|Tampa Bay Rays
|Toronto Blue Jays
The Braves come out the massive winners utilizing this system. The issues that ZiPS had concerning the staff are successfully neutralized in a postseason context. With Morton’s harm and 10 different pitchers presently on the IL, I’d be extremely involved about them fielding a pitching employees for six extra months. For 4 weeks, that danger is way decrease. Atlanta additionally has hit almost 60 extra homers than some other staff in baseball, and the lineup itself is extraordinarily stable from tip to tail. There’s a purpose ZiPS presently has the Braves with 29% odds of profitable the World Collection, which is as giant a share as I can ever bear in mind it projecting earlier than the beginning of the playoffs.
On the flip aspect, ZiPS is frightened about Miami’s gorgeous lack of offensive expertise. The beginning pitching has at all times been the massive concern for Baltimore within the projections, and whereas Kyle Bradish’s projections have inched up over the course of the season and the pc at all times appreciated Grayson Rodriguez and Dean Kremer, it nonetheless sees the highest of the rotation as missing in comparison with the competitors. Arizona at all times fared higher in ZiPS due to its depth slightly than its prime expertise (with the exceptions of Zac Gallen and Corbin Carroll). Equally, the projections noticed the Blue Jays as secure greater than explosive.
Is that this a assure that the Braves and Astros will face off within the World Collection? After all not! We’re not taking part in the playoffs 1,000,000 instances however as soon as, and when you’ve got solely probability, chaos reigns in playoff baseball.
