Within the celebration Sunday after Boston pitcher Chris Sale struck out Manny Machado to finish Recreation 5 of the World Collection, clinching a title for the Purple Sox, a lot was made about this being one of the best Boston staff ever. That’s a subject we coated as properly going into the collection, however this workforce was additionally an all-time nice squad, interval. In any case, the Pink Sox gained 108 regular-season video games and went a scorching 11-Three through the playoffs.
So, we should ask: How does this Boston squad stack up towards historical past’s biggest champions? Let’s put the Sox to the check utilizing the identical metrics we employed to guage one other current all-time champ, the 2016 Chicago Cubs. There, we checked out groups based on a handful of standards:
- Profitable proportion. With a regular-season mark of .667, Boston ranks 17th all-time amongst eventual World Collection winners. MLB hadn’t seen a 108-game winner because the 2001 Mariners, and no staff that had gained a lot had captured the World Collection because the 1998 Yankees. In different phrases, on wins alone, seasons like that of the 2018 Sox are exceedingly uncommon in baseball historical past.
- Pythagorean document. Maybe a greater decide of a group’s efficiency than uncooked W-L report is its underlying run differential, as measured by the Pythagorean expectation. And by this commonplace, the 2018 Pink Sox do drop down a bit — falling to 30th amongst all-time champs. Based on Pythagoras, Boston actually “solely” performed like a 103-win workforce that noticed considerably luck in shut video games.
- Wins above alternative. Digging deeper right into a workforce’s efficiency, we will additionally take a look at WAR (averaging collectively the variations discovered at Baseball-Reference.com and FanGraphs) to get a way of how properly its roster performed at a player-by-player degree. For Boston, WAR per recreation splits the distinction considerably between profitable proportion and Pythagorean report, rating the 2018 Sox 27th amongst champions. Their 53.Three complete WAR through the common season was virtually precisely the identical as Houston’s final season.
- Elo scores. Right here at FiveThirtyEight, we even have our personal pet metric for judging a group’s efficiency — the Elo score. In a nutshell, it tracks a staff’s estimated talent degree over time, updating after each recreation and accounting for issues like home-field benefit and beginning pitching in every contest. Simply as my former colleague Reuben Fischer-Baum did when score MLB groups a number of years in the past, right here I’m mixing a group’s last end-of-playoffs Elo with its peak and common day by day Elo from all through the season. As we famous earlier than the sport, Boston ranks ninth all-time in remaining Elo, and its blended Elo is available in 12th amongst historic champs. Elo is the class during which Boston appears greatest, because it provides credit score for each wins and margin of victory whereas additionally crediting the Pink Sox for his or her excellent playoff run.
Pulling all of it collectively, we will add up a workforce’s rating in every class — profitable proportion, Pythagorean report, WAR and blended Elo — to get a grasp rating of world champs since 1903:

Based on this measure, the 2018 Pink Sox simply edge out the 2016 Cubs (a group constructed by former Boston basic supervisor Theo Epstein) to take 18th place amongst all-time champs. That additionally places them proper subsequent to the 1975 Cincinnati Reds — the perfect model of Cincy’s “Huge Pink Machine” dynasty — and makes them the second highest-ranking World Collection winner because the ’70s, trailing solely the 1998 Yankees.
Positive, you’ll be able to complain about tanking having helped to supply an imbalanced period the place the elite groups are vastly higher than the bottom-feeders. Besides, this Purple Sox season was historic. And in contrast to its two championship predecessors — the Cubs and Astros — Boston didn’t actually backside out to assist get there. The Purple Sox completed with a very dangerous report solely as soon as since final profitable the World Collection in 2013, and even that was solely an ordinary-bad season (71 wins), not the sub-60-win atrocities a few of immediately’s tankers are forcing their followers to endure.
However perhaps the best testomony to the group constructed by Dave Dombrowski, Boston’s president of baseball operations, was what number of totally different contributions it acquired alongside the best way to the title. On the prime, there was American League MVP favourite Mookie Betts, who had 10.6 WAR in the course of the common season — top-of-the-line particular person performances ever by a participant on an eventual championship membership:

But, earlier than Betts homered to offer Boston a Three-1 lead in Recreation 5, he was hitting .200 within the postseason and was four for 21 within the World Collection. Boston was so deep, prime to backside, that it didn’t even want its MVP to play like an MVP. J.D. Martinez, who would have contended for MVP himself if Betts and Mike Trout weren’t so traditionally dominant, had an .881 OPS within the World Collection. Reliever Joe Kelly appeared in each recreation of the collection, refusing to yield a single run in six essential innings. A lot-maligned starter David Worth rotated a disastrous starting to his postseason with 4 straight rock-solid outings, incomes his second victory of the World Collection with a win in Recreation 5.
And none of these guys have been even named collection MVP! That nod went to journeyman hitter Steve Pearce, who didn’t be a part of the Purple Sox till a June 28 commerce introduced him over from the Toronto Blue Jays. After murdering the Yankees in each the common season and the playoffs, Pearce took house World Collection MVP honors with a 1.667 OPS and three homers towards the Dodgers. Even in a universe the place Edgar Renteria and Pat Borders have gained that award, Pearce is perhaps the only most random participant ever to emerge as World Collection MVP, when it comes to simply how little he’d completed in his profession earlier than shining on the sport’s largest stage:
None of that issues now, although. Pearce and the remainder of the 2018 Pink Sox are champions, they usually can take their rightful place among the many greatest World Collection winners in historical past. As my ESPN colleague Bradford Doolittle wrote final week, Boston’s efficiency in 2019 and past will assist additional inform us the place this group belongs within the context of all-time nice group runs. However when it comes to one-year performances solely, this Pink Sox season stands proper as much as the perfect the sport has needed to supply.
