But the "iron isn't hot" with Dosier, it's marginally above room temperature. Like you say later, he's been a decent hitter for about four months and prior to that, he was an aging, marginal prospect. The possibility for regression would be just as obvious to every other team. I'm not sure what sort of player you think we could get in exchange for either player, but it certainly wouldn't the salvation of our rotation. I mean Dosier would likely get us someone more like a Liam Hendricks than a Jose Barrios in any exchange, and we just don't need any more #4 starter candidates. And Rosario? A borderline top 100 prospect who's position is still not completely settled isn't going to get you a mlb ready starter who's at least a good #3 either. In either case, you will not be selling high on either player. Doser could regress, but he could also put up another season with a .720 OPS and plus-defense. If he does, he's a lot more valueable in trade than he is now. Same thing for Rosario if he hit sucessfully at AAA and shows he can do so at the ML level. Keep both.
