NEW YORK -- The Mets placed right-handers Paul Blackburn and Dedniel Nunez on the 15-day injured list on Thursday, dealing the reeling club two more blows to its staggering pitching staff.
Blackburn is nursing a shoulder impingement. The 31-year-old starter has posted a 7.71 ERA in six outings, including four starts, after making his season debut last month.
Núñez is sidelined with an elbow strain after missing two months last season with a forearm injury and Núñez, 29, compiled a 4.66 ERA in 10 relief appearances this season.
The Mets also optioned right-hander Blade Tidwell to Triple-A Syracuse.
