Mets place RHP Paul Blackburn (shoulder) back on IL

Amid a series of roster moves Thursday, the New York Mets placed right-hander Paul Blackburn on the 15-day injured list because of a shoulder impingement.
The move is retroactive to Sunday.
The Mets also placed right-hander Dedniel Nunez on the 15-day IL with an elbow sprain, while right-hander Blade Tidwell was optioned to Triple-A Syracuse late Wednesday.
Right-handers Austin Warren and Justin Hagenman were recalled from Triple-A, while right-hander Rico Garcia was selected to the major league roster.
Blackburn, 31, is 0-3 with a 7.71 ERA in six appearances (four starts) this season. Blackburn made his 2025 debut on June 2 following back and knee injuries that kept him out since August of last season.
In nine seasons — the first eight with the Athletics — Blackburn is 22-31 with a 4.97 ERA in 92 appearances (86 starts).
Nunez, 29, has a 4.66 ERA in 10 relief appearances this season while Tidwell, 24, has a 1-1 record and a 9.00 ERA in four appearances (two starts) since making his major league debut May 4.
Warren, 29, did not allow a run in two relief appearances for the Mets earlier this season, while Hagenman, 28, had a 1.50 ERA in two appearances (six innings).
Garcia, 31, last pitched in the major leagues in 2023 with the Oakland Athletics and Washington Nationals when he had a combined 9.26 ERA in 10 relief appearances.
