Presenting the Low-Seed Playoff Dark Horses
For this exercise I’m only considering teams that currently have a winning percentage under .550, since while the Yankees and White Sox are currently seeded fifth and seventh respectively in the American League, I think they’re quite good and relegated to a lower seed purely due to the quality of their divisions. They’re not sleepers, they’re just a lower-seeded contenders. Let’s begin by looking at the obvious criteria.
I’m certain this category is the one already most familiar to even casual baseball fans, let alone FanGraphs readers, who can all point at Trevor Bauer, Luis Castillo and Sonny Gray and know the Reds are especially dangerous in this respect. But I wanted to apply some amount of rigor and objectivity to this to make sure I’m not either overrating or overlooking anyone. So I turned to Game Score Version 2. It’s a nice shorthand more than it is a precise, meaningful stat, but while FIP (which I’ve also included in the following table) is a better proxy for overall pitcher quality, I wanted a measure that indicates a pitcher’s capacity to have a dominant and/or elite-level start. As such, in the table is each pitcher’s 2020 FIP, as well as how many times they’ve had a Game Score v2 start of 65 (Strong Starts) or better, and how many they’ve had at 72 (Elite Starts) or better.
Why 65 and 72? Starts with a Game Score of 65 win 65% of the time, and that’s the ratio of games a team needs to win to advance to the LCS; elite starts are benchmarked as starts with a Game Score over 72 because that’s what presumptive AL Cy Young winner Shane Bieber‘s average Game Score was this year. It’s somewhat arbitrary, I agree, but again, I’m just looking for a pitcher’s capacity to shove for seven or more innings and win a game on his own. Because some pitchers missed time due to injury and have fewer of these starts as a result, I’ve also included Shove%, which is simply the number of starts with Game Scores at or above 72 divided by the total number of starts. This can viewed as the rough chances that a pitcher has a force of nature start:
| Pitcher | Team | FIP | GSv2 >= 65 | GSv2 >= 72 | Shove% |

Next is another familiar trait of dragon-slaying playoff teams: elite relievers. Great starters can create a coin flip game but having lock down late-game relievers will win you one. You could use the WAR leaderboard for this after a full season but it takes relievers longer to accumulate meaningful differences in WAR during such a short slate, so here I just skimmed for swinging strike rate and fastball velocity as a way of illustrating who has monster late-game stuff. I also included walk rates in the table as a way of showing who is more or less likely to implode by allowing free baserunners:
| Pitcher | Team | FIP | Fastball Velo | SwStr% | BB% |

| Ryan Pressly | HOU | 2.81 | 94.7 | 17.4% | 7.7% |

Now we get to the fun, weird stuff that I think is unique to this season. First, let’s continue with pitching and talk about long men. The Division Series five-game gauntlet without off days means there is no rest for relievers built into the schedule. While this puts an overall emphasis on pitching depth, I think it makes it especially valuable to have relievers who can pitch multiple innings in the event of a blowout or extra-innings game, which, especially if your starter has been knocked out early, saves as much of your bullpen as possible for the rest of the series. The next table has a list of the lower-seeded teams’ relievers who have pitched two or more innings in an outing, as well as how many times they’ve done that this season:
| Pitcher | Team | FIP | 2-plus Inning App. |
|---|---|---|---|
| Enoli Paredes | HOU | 3.62 | 2 |
| Thomas Hatch | TOR | 4.14 | 4 |
| Ross Stripling | TOR | 6.15 | 2 |
| Chase Anderson | TOR | 6.16 | 3 |
| Brent Suter | MIL | 3.00 | 5 |
| Freddy Peralta | MIL | 1.98 | 6 |
| Alex Reyes | STL | 3.30 | 3 |
| Jake Woodford | STL | 6.71 | 5 |
| Nick Neidert | MIA | 4.51 | 4 |
| Michael Lorenzen | CIN | 3.87 | 4 |
| Tejay Antone | CIN | 3.84 | 6 |
| Lucas Sims | CIN | 3.89 | 6 |
Next is, in essence, the inverse of this. Which lineups are the best at grinding away at opposing pitchers and might be able to exploit the lack of rest days in round two of the playoffs by taking cuts off the weaker arms in their opponents bullpens more often than their opponents? For these tables we’re going team by team and looking at Pitches per Plate Appearance for each hitter, as well as their O-swing% as a way to assess ball/strike discipline. I’ve also included in-zone contact rates to show which players are best at putting balls in play, and barrel rates so that you can see who is capable of doing damage. Each team’s table has the major-league average of each stat included so you can sort the rows and see in which categories each team thrives or struggles.
| Player | Pitches per PA | O-Swing% | Z-Contact% | Barrel% |
|---|---|---|---|---|
| Cavan Biggio | 4.20 | 16.4% | 83.6% | 5.1% |
| Bo Bichette | 3.72 | 45.4% | 91.4% | 11.7% |
| Teoscar Hernandez | 4.06 | 34.3% | 76.9% | 17.8% |
| Vladimir Guerrero Jr. | 3.75 | 27.8% | 84.0% | 8.3% |
| Randal Grichuk | 3.70 | 37.1% | 84.2% | 11.4% |
| Lourdes Gurriel Jr. | 3.67 | 36.0% | 84.2% | 10.8% |
| Joe Panik | 3.77 | 21.7% | 90.5% | 1.2% |
| Danny Jansen | 3.88 | 25.1% | 84.6% | 8.8% |
| Travis Shaw | 3.90 | 27.6% | 79.4% | 8.2% |
| Jonathan Villar | 3.91 | 37.0% | 81.0% | 1.6% |
| Jonathan Davis* | 4.01 | 32.0% | 75.6% | 12.5% |
| Rowdy Tellez | 3.47 | 37.3% | 89.3% | 8.4% |
| MLB Average | 3.96 | 31.0% | 84.0% | 6.4% |
Toronto’s young lineup hits with power and I think they’d have a marginal second round advantage because of the Danny Jansen and Alejandro Kirk catching combo, as the lack of Division Series off days could mean every team’s backup catcher will have to play once or twice. Jonathan Davis has played well recently and he and Rowdy Tellez, should Tellez return from injury, would give the Jays two situational impact pieces for late in games.
But while Hyun Jin Ryu has been more consistently good than every other pitcher in the top table, the pitching thins out pretty quickly after that, and the bullpen has dealt with a compromising number of injuries. Even with all of those long relievers and Nate Pearson and Jordan Romano back, the mid-season losses of Julian Merryweather, Trent Thornton, Ken Giles and others leave Toronto thin behind a rotation that is prone to meltdowns. Ryu could steal a game in the Wild Card Series and, simply because of that the Jays are an early threat, but I don’t think they’re deep enough to be considered one in the Division Series, at least compared to other clubs here.

A Wild Card Series rotation of Sixto Sanchez, Pablo Lopez, and Sandy Alcantara (who has pitched very well in four of his last five starts) might upset the Cubs but the back of the rotation and bullpen are still clearly behind those of other playoff teams. In a perfect Marlins world, one like 2003, more of the young players would have actualized quickly. Lewis Brinson had a three-week stretch where he hit .364/.375/.618 before struggling down the stretch. He, Monte Harrison, and Jazz Chisholm are ultra-talented variables who can change a single game, but none of them appears ready to perform consistently enough to alter a series.

This team should terrify the National League. In addition to the three big starters, Tyler Mahle has had a good year and Michael Lorenzen, who should pitch out of the bullpen and pinch run during the Wild Card round, made two good starts toward the end of the regular season. This team also has one of the deeper bullpens in baseball, especially if we’re talking about the inning-eating long relievers. Lucas Sims, Lorenzen, Tejay Antone and perhaps Wade Miley and Anthony DeSclafani can all give the club multiple innings out of the bullpen. The lineup doesn’t have power from top to bottom but those who lack power grind out tough at-bats, and the club can play left/right matchups with their outfielders and upgrade their defense late with Freddy Galvis and Jose Garcia coming off the bench. I think this group could make a deep, deep run.

Houston has one of the deeper sleeper rotations and should they end up advancing to the Division Series, I think they could be pesky, but I don’t trust the back of the bullpen. Ryan Pressly is the photon of light that behaves differently when observed; he always seems to cough up games I watch, though his numbers are okay. Every single hitter in the starting lineup has an in-zone contact rate above league average but only George Springer and Kyle Tucker have barrel rates above the league average. Can they do enough damage to give the bullpen cushion? I’m doubtful.

The rotation is on thin ice because of injuries and the big pieces in the bullpen have had scary issues with walks, but the ‘pen is also chock full of guys with huge stuff, several of whom have had to go multiple innings at various points this year because of all the double headers St. Louis has had to play. Their lineup is deep, they don’t swing at balls, they do damage, and Tommy Edman’s versatility enables late-game maneuvering that enables the Cardinals to prioritize offense or defense depending on their needs. It might take Johan Oviedo taking a step forward or Alex Reyes moving into the rotation in round two, but St. Louis has a shot to go deep.

The Corbin Burnes injury is a knockdown blow that stymies Milwaukee’s hopes at making a deep run. Losing Burnes not only costs the Brewers their best starter but weakens the bullpen since Freddy Peralta or Brent Suter will almost certainly be deployed to eat innings in his stead at a time of necessity rather than when it’s strategically advantageous. The lineup slugs but also chases and whiffs a lot. With Burnes, I’d have Milwaukee right there with St. Louis and Houston in tier two of this contingent; without him, they’re closer to Toronto.
