It’d be rather unfortunate if the arrival of Miles Mikolas cost Irvin his rotation spot, since Irvin is at least as good of an innings eater and might theoretically still have some upside. Then again, Irvin could prove more interesting out of the pen if the Nationals give him a look there. It’s not an easy call; Irvin is probably more valuable to the rebuilding Nats while throwing 180 mediocre innings, but if his stuff took a step forward as a short reliever, that could draw the interest of contenders.
