Misiewicz is off to a fantastic start to the season out of the Mariners bullpen, tossing 3.2 scoreless innings with two strikeouts and zero walks. There was no clear details that were released, but this does not necessarily mean there has been a positive test. He could have been exposed to someone with COVID or could have something to do with protocol. He can be activated once he is cleared. The Mariners called up Erik Swanson as a result of this move.
