Matt Moore is back in the major leagues with the Seattle Mariners after a lengthy absence from the team. Moore was hit in the head twice in as many days this season, forcing him to be placed on the seven-day concussion list. Last season, Moore missed nearly all of Mariners summer camp, missing nine games in August due to COVID-19 and a wrist sprain. Moore’s re-entry into the lineup this year might change the course of his career.
