Tulo may be one of the most untradeable players in baseball. After guys like Cabrera and Pujols.
The best you can hope for is a bit of hope at the end of this season, and hope he provides some positive WAR in 2019, perhaps making him a trade candidate, and you would still be getting no return and eating 80%+ of his salary.
I would love to just DFA Morales, Tulo and (possibly) Martin, Pearce, etc. But it's not a video game.
Actually, I sort of like the idea of keeping Martin around next year to mentor Danny Jansen, and play 1/3 games. A bit expensive at $20M, but we paid a premium to get him to come here, when it was really tough to attract any free agents. Plus I think Martin is a top shelf guy. And a canuck. I love canucks. Because we are the s***.
