As mentioned above, I've had it with Brendan McKay and after yet another terrible outing I was ready to move on. As a reliever, Dunn has 70 stuff, 55 movement and 50 control and Seattle was using him as their closer, but I plan on having him pitch multi-inning middle relief with an eye toward making him a starter next year (or this year should we have another injury, always a possibility with Chris Sale in the rotation). We were a bit too lefty-heavy in the pen with Poche, Vesia, McClanahan and Fletcher already on the staff so this move gives us balance too.
