The New York Mets have placed rookie right-handed reliever Dedniel Nunez on the 15-day injured list due to right forearm tightness, retroactive to August 26. This marks a disappointing setback for Nunez, who had just returned from a prior forearm strain and made one scoreless appearance against the Padres. Mets manager Carlos Mendoza expressed that Nunez was 'not recovering well' after his latest outing, highlighting the ongoing challenges for the Mets' bullpen as they strive for postseason contention. Nunez has performed well in his rookie season, boasting a 2.31 ERA and a strong strikeout-to-walk ratio. The Mets have opted not to call up anyone to replace him immediately, as Tylor Megill is set to return to the rotation to fill another gap. The duration of Nunez's latest absence remains uncertain.
