Not sure what you are trying to say is true.
Cole hasn't pitched less than 6 innings since he third game or less than 91 pitches since his 3rd start, and 3 of those 8 starts 7 innings or more.
Cortes has went at least 7 in 4 of his last 5 and the other was at 100 pitches after 5. They did ramp him up a bit but only once pitched less than 82 pitches.
Taillon has went at least 7 in three of his last 4 and the one he didn't wasn't great. They did ramp him up for a few starts but only 3 times less than 82 pitches.
Severino who has pitched 7 games since 2018 ( I guess the Yanks haven't gotten the Covid memo), has pitched at least 7 in 2 of the last 4 and the other two went at least 6. Only twice has he pitched less than 83 pitches.
Montgomery has pitched at least 6 in 3 of his last 4, he does seem like the one guy that might be considered similar to what the Twins are doing, Most of his starts are in the 80 pitch count, but 5 of his 11 starts have been 6 plus innings, and 4 others over 5.
Are there teams pulling starters after the 4th or earlier, sure there but to say that is how every team uses pitchers is absolutely not a true statement. Just in yesterday's games, maybe you could say Oakland did it. Cincy pulled a guy doing great (6 innings, 3 hits, no walks) in a 9 - 0 game, and that turned in a 14 - 8. The Dodgers pull White after 5 innings of 2 hit no walk ball and 69 pitches, and the next two pitchers each gave up 2 in an inning total. They lost 4 - 0. The Brewers also pulled a starter after 5 with 79 pitches, they lost as well (Hader's 1st blown save). Otherwise ever starting pitcher went to around 100 (maybe more) or 6 plus innings, unless they were terrible.
You can go back every day and things look similar at least since pitchers have been stretched out, so are there teams pulling guys early, yes absolutely but not at the pace some people on here are saying it is happening.
People talk about the Rays, there last 6 games from their starter - 6, 1.2(6 runs), 7, 6, 3, 6 ,6
