First of all, I would bet Twins starters don't go 6.2 innings even 30 times in 2026. They averaged just over 5 in 2025.
You'd still need 2, probably 3 relievers when they do. And you cant be sure your 2 "high leverage" guys are even available for those few games when your starter DID go 6.2. Not to mention the other 140 games when they don't and youre using 4 or 5 relievers night after night. All while missing a couple of relievers off your opening day roster because, well, guys get hurt. A lot. So your bullpen really needs to be about 10 or 11 deep.
There is virtually zero chance the Twins bullpen is even anywhere near mediocre in 2026.
