Basically Chavis and table scraps for Bradley?
I don’t think many teams are so eager to get Brian Johnson, since many teams have out-of-options AAAA pitchers in their late 20’s. Some teams might be intrigued by Swihart, but when you’re shopping for bargains, you don’t pay full price. That’s why I guessed an equal wild card one-for-one swap for 28yo Tayron Guerrero and his 98mph fastball made some sense for both teams (assuming Miami ever deals Realmuto and doesn’t get a catcher back).
And most teams already have a guy like Hector Velasquez.
Archie Bradley isn’t a relief stud every year, but he does have that ability. (2.1 fWAR in 2017). And he makes very little money and has a few years left. If the Diamondbacks do trade him, they will need some serious enticement. From the Sox perspective, the opening bid might need to include two of Chavis, Dalbec and Darwinzon Hernandez at minimum.
If you were GM of the Diamondbacks, would you trade your best relief pitcher for Chavis, Swihart, Johnson and Velasquez?
