Another potentially interesting name that hasn't been kicked around much (if at all) is Eric Thames. Fits as a lefty bat with pop, could platoon with Camargo in LF, and comes with no long-term commitment ($6 million this year, $7.5 million team option in 2020). Might not cost an arm and a leg since they have Santana and Broxton there and ready, and Ray getting close.
Not sure Julio would be enough to get him, but how nice would that be? AA could then focus on Gray (assuming he's still sniffing around there) without HAVING to have Frazier as part of the discussions. IF you could get him for Julio it saves ~ $5 million...
Work out the deal for Gray by himself ($4 million added when you apply the savings)
Release Duvall and sign Gonzalez (~ $7 million added)
Acuna, Donaldson, Freeman, Thames, Flowers, Albies, Ender, Dansby
Mac, Camargo, Gonzalez, Culberson
Folty, Gray, Newk, Gausman, Touki
Use the rest of the money to add Soria or Miller to the pen. Even if Julio isn't enough to get him, you'd still think they wouldn't mind clearing Thames' salary to use to chase another Pitcher.
