The New York Mets placed right-hander Jose Butto on the 15-day injured list Friday due to an unspecified illness.
The move is retroactive to Tuesday for the 27-year-old reliever, who is 2-1 with a 2.47 ERA in 31 relief appearances.
He joins a crowded injured list that already includes 12 other Mets pitchers, including Kodai Senga and Sean Manaea.
Butto is 10-8 with a 3.13 ERA and four saves in 71 career games (15 starts) since making his debut with New York in 2022.
The Mets recalled right-hander Chris Devenski from Triple-A Syracuse to take his place on the 26-man roster.
Devenski, 34, has no decisions and a 3.60 ERA in four relief appearances this season, his first with the Mets and 10th in the major leagues.
