Minnesota Twins designate Trevor Richards, claim Michael Tonkin, add Caleb Boushley, and move Joe Ryan to 60-day IL.

The Minnesota Twins have designated right-hander Trevor Richards for assignment, claiming right-hander Michael Tonkin off waivers. Caleb Boushley was selected from the contract to replace Richards in the active roster. To make room for Boushley on the 40-man roster, Joe Ryan was transferred to the 60-day injured list. Richards had a 4.15 ERA in 13 innings with the Twins, while Boushley returns for his second stint with the team this year.
