Dedniel Nuñez, once a promising pitcher for the Mets, has struggled to find his rhythm after returning to the majors this season. Following a series of inconsistent outings, he was sent back to Triple-A Syracuse to work on his command, having allowed six walks in his first appearance. Manager Carlos Mendoza emphasized the need for Nuñez to regain his strike zone consistency to replicate last season's elite performance.

In related news, left-hander Jose Castillo was added to the Mets roster after being acquired from the Diamondbacks, looking to bolster their bullpen. Castillo, who has battled injuries, is viewed as having potential upside. Meanwhile, infielder Ronny Mauricio has been optioned to Triple-A after completing a rehab assignment, focusing on adapting to daily play after recovering from knee surgeries. Paul Blackburn is also poised to make a final rehab start before returning to action.
