D-Backs pitcher A.J. Puk has been diagnosed with a flexor strain and will be shut down from throwing for 2-3 weeks before reevaluation; fortunately, surgery is not expected. Puk, who was placed on the 15-day injured list on April 19, will likely not return to the mound until June, potentially missing time beyond the All-Star Break. His absence increases pressure on Justin Martinez to step up as a late-game option, supported by teammates Shelby Miller, Kevin Ginkel, Jalen Beeks, and Ryan Thompson.
