I had not heard that fastball spin rate was important until the narrative started this year. Before this year, fastballs were about velocity and spin rates were for breaking balls.
So, going back to the truths about fastballs, yes Maeda's fastball velocity is significantly down this year. It's the lowest it has been since his rookie year.
I am not sure what you mean about truths. I appreciated and bookmarked this fivethirtyeight article from 2018 on fastballs, spin rates and swings and misses.

But how can a player — or a whole team — develop high spin rates? Some players have high fastball spin rates innately, and others don’t — changing grip on a breaking ball can change spin rate, but it’s difficult to throw a fastball differently. Unlike velocity, which can betrained, a pitcher’s fastball spin ratio is thought to be extremely difficult to alter naturally.
The unnatural solution is for a pitcher to apply a foreign substance. In May, Cleveland Indians pitcher Trevor Bauerdrew the ireof the Houston Astros when he addressed the subject of sticky substances and their effect on performance.
“There is a problem in baseball right now that has to do with sticky substances and spin rates,”Bauer said. “We know how it affects spin rate and we know how spin rate affects outcomes and pitches and movements that have a big difference in a game, a season and each individual player’s career.”
“The people who choose not to do it are at a competitive disadvantage.”
You all care about this site. The next step is caring for it. We’re asking you to caretake this site so it can remain the premier Twins community on the internet.
Twins fans seriously have to start letting the GM General manage and the manger manage and the players play. Getting really annoyed with twins fans in general these last few weeks.
