Yes, they really are throwing
fewer fastballs (defined here as four-seam and sinkers) than any team in the pitch-tracking era, dating back to 2008. We don’t have reliable data before that, other than to say that it’s extremely hard to believe anyone in baseball history earlier than that was really throwing fewer fastballs, so it’s reasonable to think this might be
the least fastballing team ever.
Lowest fastball rate, 2008-pres. (2020 excluded)
- 35% – 2024 Red Sox [It was 48% in 2023.]
- 41% – 2024 Rays/Twins, 2022 Rays,
