I'd guess this is unpopular. And as a preamble, i'd say he is a valuable pitcher right now due to his health and inning eating in the regular season. The regular season part is important.
But, the trade i would make at the deadline is trading Berrios. He is under the hood declining. By pretty much any underlying stat he is our fourth best pitcher right now, and that is with me assuming that Lauer is over performing. And if i was the gm i'd take probably the last chance off that contract at the deadline. And i'd also want to take it out of the manager's hands whether to start him in a playoff game.
All his fastballs are down about a tick this year. He has the 5th lowest xFIP, the 5th lowest xERA, and 5th lowest Sierra. Among starters.
He has the worst stuff+ (worse than bowden francis) as basically all his pitches are below average. And a 94 pitching+.
This is simply not a guy you want to take the ball in a playoff game and honestly if his velo takes another tick down he could be a problem in the rotation next year. He also has 66m left after this year. I don't want to pay $66m to a guy who rationally shouldn't start a playoff game.
He also has a great ERA and years of proof that he can stay healthy. Contending teams will want pitching at the deadline and its possible we could get off this contract.
For example, the Angels always need pitching. They are fighting for the playoffs and are willing to run an above average payroll. We could try Berrios for detmers plus other stuff. They would get a starter. We'd get a leverage reliever.
Then we can trade prospects for someone who can start a playoff game (expensive) and a back end starter (cheaper).
I'd suggest Severino for the first one as he fits into Berrios' money, and he has a truly elite slider, so if he has bad form, he can fit in in leverage in the bullpen come playoffs. The As will also probably want off that contract.
Then we could run a rotation of Gausman, Scherzer, Severino, Bassitt, Lauer/back end starter.
I don't think this is the kind of move we do, and its possible every other team looks at him and just wants nothing to do with that contract, but i would attempt this at least.
