If I'm GM, I don't want to mess with success in 2019. But Arraez has stepped forward and is in my plans for next year. So I'm in general agreement with the OP. Arraez has become the kind of player I keep, unless someone absolutely knocks me over with a trade offer. I trade prospects who haven't stepped forward, such as Gordon, and let the other team shoulder the risk, and if that means less in return, so be it. Schoop's been good this year, until the month of June, but that's too short a time to be making moves over - he'll probably bounce back and his defense has been good. If for some reason Schoop was integral to trading for a good starting pitcher, I'd consider it since I do have his replacement in mind, but it's doubtful a trade would work out that way. So in November I'd thank Schoop profusely for his contributions, make sure he knows he's invited to the WS Ring Ceremony next spring, and offer to give a glowing reference to his next employer.
