The Mets announced a large slate of roster moves this morning, most notably placing righty Reed Garrett on the 15-day injured list due to a sprain in his right elbow. New York also selected the contract of righty Wander Suero from Triple-A Syracuse, designated right-hander Dom Hamel for assignment, recalled righties Huascar Brazoban and Chris Devenski from Syracuse and placed lefty Sean Manaea on the paternity list.

There’s no immediate timetable for Garrett’s return, but the 15-day IL placement ends his regular season. Taking a step back, any news of an elbow sprain — which by definition signifies stretching/tearing of a ligament — is an ominous development for a pitcher. That’s especially true in the case of Garrett, who only recently returned from a two-week IL stay due to inflammation in that same elbow. Presumably, manager Carlos Mendoza will have more information prior to this afternoon’s game against the Padres.

Garrett’s loss is a notable one for a Mets relief corps that has struggled amid what increasingly looks like a late-season collapse. They still hold the final NL Wild Card spot, but the Mets have dropped 10 of their past 13 games and only recently snapped a disastrous eight-game losing streak. The Mets are just 16-27 since the trade deadline passed — a .372 winning percentage that effectively matches the season-long mark of the rebuilding White Sox.

Shoddy bullpen work has been a critical factor. Mets relievers have posted a collective 4.76 ERA since Aug. 1 — the sixth-worst mark in the majors. The typically steady Garrett has contributed to those woes, yielding a run per inning over the course of a dozen frames in that time. It stands to reason that those struggles are tied directly to his elbow injury; Garrett was sporting a tidy 2.45 ERA in 47 2/3 frames before being shelled for eight runs in a span of five appearances and heading to the injured list. He was effective for the ’24 Mets as well, logging 57 2/3 innings with a 3.77 ERA and huge 33.6% strikeout rate.

More to come.
