Why? He was available for free last month and nobody wanted him. I know he's had a good month, but I doubt that's rebuilt his trade value to the point where somebody is taking on his contract and giving something of value. I've shared this sentiment before, but 'Castro clearing waivers means the baseline for his trade value is literally zero' is simply not true. Teams have different motivations and risk tolerances in August, and generally the default is letting a player pass through waivers out of courtesy if nothing else. We're 10 months removed from Matt Kemp's corpse and bloated contract getting insane value in trade, and he didn't have Starlin's youth, health, positional advantage, friendlier contract, or insane September to promote optimism. I obviously have no insight as to how GMs view the waiver wire, but I just can't imagine a team like the Padres letting Castro slip through waivers simply out of courtesy if they felt his contract was at all friendly. I'm not saying he's untradeable, but I think people need to scale back expectations on getting anything of real value for him at this point.
