I was intrigued by the the Red Sox dealing Marcello Mayer. Personally I don't think there is anything wrong with Mayer or Kristian Campbell that's not a direct result of their injuries. Mayer was a good buy-low for the Giants, and Campbell will be the same for somebody as well.
I think that other than the Cubs and the Dodgers, nobody really went for it. That's frustrating as fuck when you are rooting for a seller, but it is what it is. Most teams overvalue their prospects. The Brewers and Rays were probably thinking that not outbidding the Dodgers for a playoff run with Skubal will give them more opportunities down the road to be buyers and then not go for it.
To accommodate the Arraez acquisition, the Phillies are moving Byson Stott to third, Alec Bohm to first, and Bryce Harper back to the outfield. It will be interesting to see what kind of hellfire rains down on their GM over this.
