The New York Mets have made significant roster changes, designating right-handers Adrian Houser and Shintaro Fujinami for assignment while activating ace Kodai Senga from the injured list. Houser struggled this season with a 5.84 ERA over 69 1/3 innings, and his recent performances led to his DFA, despite an earlier solid stint in relief. Fujinami, who had not pitched for the Mets this season due to injuries, was also DFA'd after a disappointing tenure. The Mets placed reliever Dedniel Núñez on the 15-day injured list due to a right pronator strain and recalled Eric Orze from Triple-A Syracuse to fill the bullpen gap. The Mets are currently positioned for a Wild Card slot in the National League with a 54-48 record. These moves come as the trade deadline approaches, and the team may seek further reinforcements in the bullpen.
