Donaldson is making like $20 mil per year, maybe slightly less (top of my head). Zero percent chance the Twins take on a contract like that, nor should they for a 33 year old on the downslope, IMO. Also, they're pretty similar hitters. Big power numbers, high on-base. Sano Ks more, but Donaldson Ks enough in his own right. Defensively, Donaldson has the edge. Overall, Donaldson is about 1 WAR better than Sano this year. Sano is much younger, much cheaper, under team control for the foreseeable future, and IMO will get even better. 1 win for a huge salary difference, that could return a serviceable starter AND a solid bullpen peice, just doesn't add up. That would be an awful trade. Then, as we watch Donaldson decline, or worse (retire, leave via free agency, etc), we get to watch Sano be one of the elite hitters on earth for the next decade. So far this year, I've seen: Calls to outright Gibson. He's carried the rotation since the end of July. Calls to trade Rosario for whatever pitching they can get. He's one of best LF in the AL, and has been one of the best hitters in the game since before the All-Star break (this take was on Sept 7, mind you, which is hilarious). Throw in the typical Mauer takes to frost th cake. And, the best of all. The high-end certifiable institutionalizeable take: for Granite to replace Buxton,and trade Buxton for whatever they can get at his lowest point. Buxton turned around to be a top 5 position player in baseball since July 4. I feel pretty good about what Sano will do going forward now that we got the first "He's a bum, get rid of him" take out of the way.
