Here is something I read on the subject:
“It would be hard to trade him,” a rival scout said. “I would think the fan base would have to have something to hold on to. He’s really the face of the organization. It would be hard to part with that.”
They also could go a different direction – a contract extension – but that likely would not come easy. Last season, Goldschmidt switched representation to Casey Close, a high-powered agent who has negotiated record-breaking deals for Clayton Kershaw and Greinke. An extension could conservatively cost the Diamondbacks in excess of $20 million per year – and perhaps much more.
Not only would that sort of deal be difficult for the Diamondbacks to afford with Greinke already on board through 2021, it also would be risky to devote those kind of resources to a player who will be in his mid-to-late 30s, particularly for a team with payroll limitations.
If they do face a rebuild, they’ll have to confront the same questions as they relate to center fielder A.J. Pollock, who will be eligible for free agency after next season.
Capitalizing on Goldschmidt’s and Pollock’s prime was part of what compelled the club to sign Greinke and trade for Shelby Miller prior to last season. And while it hasn’t happened yet, it’s possible things turn around this year. That, at least, is what the Diamondbacks are hoping.
