DUST is (as always) settling upon the most recent MLB season, with awards presented and the hot stove's pilot light already engaged (the husky Josh Naylor re-signing with the Mariners--the third team to own him in less than a year...sign o''the times).
We enjoyed the recent work of baseball's epiphenomenologist Sam Miller, who ratcheted together an apparatus to gauge a form of aesthetic greatness in the World Series that resulted in the improbable discovery that the just-completed skirmish between the Dodgers and the Blue Jays ranks #1 all-time. While the tool probably needs one or two added components and a secondary pass with a weighting mechanism, it does capture many salient attributes for what it attempts to measure; while it's more "pebble-gathering" than "pebble hunting" (we await the baseball cap logo for Sam's Substack side hustle...), it has the makings of a satisfying book-length journey and we hope to see it in that form someday.
BUT here, of course, we're here to toss boulders around as we continue to measure the things we increasingly disparage (and often outright despise). Our urge toward the "micro", however--as manifested recently with our most outlandish proposal to date--keeps us safely away from the keys to the kingdom (at least for now...)
And so we return to our ongoing exploration of the power phenomenon that is often as maudit as it is Herculean--the 10+ homer month. When we left off (in our rather fallow coverage of the game in 2025) it was the end of April and there were only three such achievements, the most dramatic owned by the gargantuan Aaron Judge.
AT year's end, of course, Judge had three such months for the season--which was not the most for any player, however: that achievement landed on the broad shoulders (and possibly even broader posterior) of Cal Raleigh, who had four such months en route to a 60-homer season, setting a record for catchers and switch-hitters (and, of course, for switch-hitting catchers).
Here is (borrowing shamelessly from the brash young Thomas Pynchon, who released his tenth novel during baseball's post-season at the ripe old age of 88) the "whole sick crew" of salacious sluggers, anchored by two likely Hall of Famers (Judge, of course, and Shohei Ohtani, both of whom became only the fourth and fifth members of a club we might call repeat offenders--sluggers with back-to-back 50+ HR seasons).
As you'll see, Ohtani had the biggest homer month in '25, with 15 in May. No one else had more than twelve in a month (Kyle Schwarber did it twice, en route to 56 for the year--making him into the post-modern equivalent of Hack Wilson).
The truly great months (with OPS values in excess of 1.200) are highlighted in bold type (and garish color--we don't mess around, even when we're messing around!). There are five of them--and three belong to Judge. (The overall best month according to OPS, however, belongs to AL Rookie of the Year Nick Kurtz, who terrorized pitchers to the tune of a .953 SLG during July.)
All in all, there were 28 10+ homer months in 2025--which leads us to our updated TimeGrid™presentation of the year-by-year history of 10+ homer months ever since Babe Ruth invented them in 1920...
The evolving record for most in a season is shown in bold type--it first hits double figures in 1930, and that remains the record until the expansion year of 1961, an occurrence that prompted the strike zone change two years later (and you can see the impact of that in the bolded box area in the sixties row).
The record was tied in 1995, shattered the following season, and the still-current record was set in 1999. Two seasons--2001 and the ridiculous year of 2019--came close to toppling it, however. (In case you are wondering what the seasons in red type signify, those are the three seasons with abbreviated schedules--by player strikes in 1981 and 1994, and by the pandemic in 2020.)
Note also that 802 of the 1333 10+ homer months have occurred since 1990. (That's 60% in the past 36 seasons, as opposed to 40% over the span of the first seventy seasons. We are all Sluggos...)
WE will close with another way to look at the increasing ubiquity of the 10+ homer season. It's possible to adjust the data to reflect the average number of such seasons per team over any given year. Recall that there were only sixteen teams in MLB for the first 41 seasons of the 10+ a month era (1920-1960).
As the chart shows, the first spike for 10+ HR a month sightings occurs in 1930, but subsides for most of the 1940s. It first became relatively ubiquitous in the 1950s (note the significant jump in the decade average, from just one such month for every four teams in the 40s to two out of every three teams in the 50s).The expansion year peak in 1961 (1.28) set a record that wasn't exceeded until 1996, with the current high-water mark set in 1999. Once again, 2001 and 2019 (annus ridiculous) came extremely close to setting a new record. The temporary lull we saw in the first half of the 2010s is long forgotten.
The decade-level averages appear to be stabilizing at something similar to what was seen back in the 1950s. The values we're seeing in this decade, however, are more consistent that what was the case in the 2010s, and are consistently higher than what we saw in the 1950s, so by decade's end we could see an average that is somewhere between the levels in the 1990s and 2000s.
We are also seeing a rise in low-BA 10+ homer months (defined as those months were the Sluggos batting average in such a month is below .250). The yearly record for this growing sub-category is (not surprisingly) the ridiculous year of 2019--but we had seven of them in 2025. (The record-holder for this feat, by the way, is the poster child for the still-virulent "launch angle age"--yep, that's right: Kyle Schwarber--five times...and counting.)
Stay tuned....
