Yeah I'm sure they will still sign someone on a one-year deal, and/or bring in someone on a minor league deal with a highish major league salary if they make it.
But you never know, we could also see a trade like last year.
They really need Soto to be someone who can get RHP out if they don't add anyone, along with Kerkering being ready. But they certainly do have enough arms currently, especially if one of Brogdon or Bellatti can bounce back.
Alvarado
Seranthony
Hoffman
Strahm
Kerkering
Soto
TBD (Bellati, Brogdon, Yunior Marte, Michael Mercado)
Covey
That's a good enough bullpen for almost any team in any era, it's just that the current era puts a higher premium on a 6th inning guy, which used to be an incredibly fungible spot (along with the long/mop-up guy).
But they could also really stand to have that last or second-to-last spot be an optionable arm. Signing another vet would make that harder too (though obviously Covey is still not sure to make it).
The social media rumor business is dumb for sure, but Morosi did not predict any of those three teams would sign, and merely said they were "among" the clubs with interest. There's really no way to ever be wrong when it's that vague. I'm sure the Phillies had "interest" in Hader too. Just not serious interest or actual discussions.
