Cardinals reliever Scott Blewett has opted out of his minor league contract, prompting St. Louis to either add him to the MLB roster or release him. Despite a 5.18 ERA in Triple-A Memphis, Blewett has a solid 28% strikeout rate, although his MLB track record shows a modest 19.3% strikeout rate over four seasons. The Cardinals, with a struggling bullpen ranking 17th in ERA, may consider replacing a current pitcher to keep Blewett. They will need to create 40-man roster space, potentially designating a player for assignment or placing someone on the injured list.
