understand your point, but Tork is more highly regarded. And Kellenic has failed miserably in two separate MLB trials. Also, if the Tigers were a playoff contender, they might be open to a similar move, if they could get players to put them over the top. I'm too lazy to look at the Mariner's bullpen, but if getting Soto and Fulmer, along with one of our better prospects would free up a player they don't expect to contribute this year, they might be more open-minded to it.
I get it, though--we overvalue our own players/prospects.
