Red Sox Bullpen Takes a Hit as Justin Slaten Shut Down for 2026
MLB Trade Rumors reported that the Red Sox expect Justin Slaten to miss the remainder of 2026.
The bullpen just took another hit, and this one comes with a side of degenerative elbow changes. According to MLB Trade Rumors, right-handed reliever Justin Slaten is officially done for the remainder of the 2026 season.
Slaten originally hit the injured list back in mid-August with what was called right elbow inflammation. Now, doctors have found degenerative changes in his right flexor mass, meaning his year ends with a PRP injection instead of a late-season return to the mound.
If you just look at his 6.48 ERA, you might think losing him is a net positive for . But that number is a massive lie. Slaten actually threw scoreless baseball in 15 of his 19 appearances this year. He just happened to give up four runs in a single outing twice, which is the statistical equivalent of eating a salad every day for a month and then swallowing a whole deep-fried turkey on a Tuesday.
Before his elbow started barking, Slaten was actually floating around as a sneaky trade chip. He had a career-best 26.3 percent strikeout rate in his 16.2 innings of work, and his underlying metrics looked way better than the surface-level disaster. Now, any team that was calling about his three remaining years of team control is going to lose the number.
This is just brutal timing for a squad that is already leaking oil. The Red Sox just dropped three out of four games to the and opened their current series against the with a 4-2 loss. If you are holding a ticket on to make any kind of late-season run, you are officially sweating.
Slaten will spend the rest of the year rehabbing in hopes of being ready for 2027. Meanwhile, the have to figure out how to patch together the middle innings against tonight without one of their most deceptively effective arms.
