Yes to the above.
And as you mentioned trade Urias, for a solid bull pen arm.
I think Urias is here as the bridge to Holliday, perhaps as a backup plan, if he doesn't make it out of ST. Had we kept Ortiz, then we wouldn't need him even in that scenario, but I'm not comfortable giving Mateo or Norby everyday at bats even for two months, so I like keeping Urias around for a little while and then looking to deal him mid-year when Holliday is promoted (or keeping him as the utility guy if Mateo's bat is as bad as it can be and the CF glove doesn't work out).
I'd have no issues at all with flipping him for a reliever or even prospects, it makes sense, but I also think there is value he provides to the current roster if Holliday isn't coming North.
