Red Sox DFA Danny Coulombe on Day 1 of MLB Draft

The Boston Red Sox have designated left-handed reliever Danny Coulombe for assignment on Saturday after he went two innings against the Mets and walked three. Coulombe struggled through the 2026 season producing a 4.95 ERA in 20 innings of work with a 1.50 WHIP and an 11.4% strikeout rate versus a bloated 13.6% walk rate. The underlying numbers backed up his performance this season, as he produced a 4.71 FIP and a 5.91 SIERA. 

Coulombe was brought in as lefty help in the spring, with only closer Aroldis Chapman profiling as a legitimate left-handed option, but he did not meet the expectations set for him.

One interesting note from Chris Cotillo, who broke the DFA news:

So it seems that beyond his play this season, there was legitimate financial incentive for the Red Sox to make this move. No corresponding transaction has been announced yet.
