Red Sox designated RHP Tommy Kahnle for assignment.
Kahnle was charged with four runs during his lone inning of work on Tuesday against the Nationals, leaving him with an inflated 8.00 ERA across nine innings since joining Boston’s relief mix back on June 4. It’ll be Alec Gamboa coming up to take his roster spot ahead of Wednesday afternoon’s contest, according to MassLive.com’s Chris Cotillo.
