MLB Injury Updates & Roster Moves
The Seattle Mariners placed third baseman Brendan Donovan on the 10-day injured list, retroactive to Saturday, due to a left groin muscle strain, while simultaneously calling up reliever Matt Wilson to manage the short-handed roster. Compounding bullpen issues across the league, the Los Angeles Dodgers announced that closer Edwin Diaz requires surgery this Wednesday to address loose bodies in his right elbow, projecting a potentially significant absence for the National League West leaders. Meanwhile, Cubs manager Craig Counsell criticized an existing MLB rule allowing the Dodgers to maintain a 14-pitcher roster specifically because of Shohei Ohtani’s unique status, labeling the current regulation as "bizarre" given the roster flexibility it grants the Los Angeles club due to Ohtani.
