Kelly had an indelible stamp on the 2018 team. He started the year by blowing game 1. He became Jim Buchanon and started a Joe Kelly Fight Club faze when he called out Tyler Austin of the Yankees. Then he became an afterthought and albatross around the neck of the bullpen as the summer dragged on.
But then, in the playoffs, the mid-bullpen became a strength, because he became a strength. In six innings in the World Series he had a 0.00 ERA and 10 strikeouts. That is domination.
