Interesting video. I wish there had been an explanation of how using foreign substances increases spin rates, or why increased spin rates makes baseballs harder to hit.
Much of the b-roll in the video is from past seasons. If the video creator has been immersed in the issue as closely as he suggests, he might have dropped in the clip of the ball sticking to Yadier Molina’s chest protector.
I don’t like the clip of Ohtani as if Ohtani is part of the conspiracy. Ohtani’s spin rates have increased, but not so much that it couldn’t be attributed to the manufacture of the 2021 baseball itself (for example, raised laces). Same with deGrom, in my opinion, by the way. I do recall in 2019 that pitchers said they couldn’t grip the baseballs. Maybe the foreign substance talk this season is a reaction to how baseballs were made that season.
Like someone said, baseball cannot seem to get out of its own way.
People can click here to go to Baseball Savant and do their own investigation. Start by searching a player’s name, then on the player’s page scroll halfway down to the Pitch Tracking section, then click on More Seasons. Spin is one of the last columns. It’s really nice that MLB makes this information publicly available.
