The Mets are going to designate right-hander for a signment, reports . That will be the corresponding move for the promotion of , a move that was . Blackburn was acquired by the Mets at last years trade deadline. At the time, the Mets had lost both and to the injured list and suddenly needed a bit of rotation depth. He made five starts for the Mets before he himself required a stint on the injured list. He hit the IL due to a right hand contusion. While on the IL, it was reported that he was dealing with a spinal fluid leak in his back. He didnt make it back off the IL. He underwent a cerebrospinal fluid (CSF) leak repair procedure in October. Despite the rough landing in Queens, the Mets tendered him a contract for 2025, his final arb season before reaching free agency. The Mets seemed interested in stockpiling rotation depth. They signed , , and , adding to a rotation mix which already included Senga, , and Blackburn. The Mets and Blackburn avoided arbitration by agreeing to a $4.05MM salary for this year. Unfortunately, it has turned into another season marred by injuries and the Mets seemingly never had much interest in putting him back into the rotation. He likely would have been off the roster long ago if not for other injuries, both to himself and others. Blackburn started the season on the IL due to inflammation in his right knee. He was rehabbing throughout May, before being reinstated from the injured list in early June. By the middle of June, there was that the Mets were fielding trade interest in Blackburn. At the time, they had a rotation of Senga, Peterson, Holmes, Canning and Megill, with both Montas and Manaea on rehab a signments. Blackburn appeared to be surplus to requirements. But moments after that report came out, Senga got injured and landed on the IL. Megill went on the shelf not long after. That opened a window for Blackburn to stick around, but then he himself hit the IL again in early July due to a right Quentin Musty Jersey shoulder impingement. He began a rehab a signment in the middle of July and got up to five innings by his second outing. But the Mets didnt have a rotation spot for him behind Senga, Manaea, Holmes, Peterson and Montas. They let Blackburn throw a few more rehab starts, perhaps because they just wanted to keep him around in case someone else got injured. In recent days, Montas was moved to the bullpen to open a rotation spot for McLean. Blackburn was reinstated from the IL and put in the bullpen as well. He to sed five innings of long relief on Wednesday after Peterson couldnt get through the fourth inning. Now, hes been bumped off the 40-man entirely. This move ends a strange Mets tenure for Blackburn. He was technically with the club for over a year but only made 12 appearances in orange and blue. It often seemed like the Mets were on the verge of nudging him out the door before it finally happened. He now heads into DFA limbo. With the trade deadline having pa sed, he will have to be placed on waivers. There is just under $1MM left to be paid out on his salary. His frequent injuries likely hurt his chances of being claimed, though he has had some decent results when healthy. With the Athletics in 2022 and 2023, he to sed a combined 215 innings with a 4.35 earned run average. His 20.7% strikeout rate, 7.8% walk rate and 44.5% ground ball rate were all fairly close to league averages. Those cromulent results surely attracted the Mets in the first place but he wasnt spared the injury bug even in those campaigns. I sues with his right middle finger prevented him from surpa sing 115 innings in either of those seasons. Still, decent starting pitching is hard to find after the deadline, so perhaps Blackburn will find some interest. If he clears waivers, the Mets will remain on the hook for the rest of his salary. At that point, another club could sign him and pay him the prorated portion of the league minimum salary for any time spent on the roster. That amount would be subtracted from what the Mets pay.
