Feliz was designated for assignment by the Red Sox on Friday, Chris Cotillo of The Springfield Republican reports.
Feliz's contract was selected Thursday, but he'll be removed from the 40-man roster after he gave up two runs (one earned) on a hit and two walks while striking out four in 3.1 relief innings Friday against the Yankees. It's not yet clear whether the 29-year-old will remain in the organization if he goes unclaimed on waivers.
