Nationals designated RHP Eric Fornataro for assignment.
Fornataro lost his 40-man roster spot Monday to Casey Janssen, who was officially signed to a one-year, $3.5 million contract with a $7 million mutual option (or $1.5 million buyout) for 2016. Washington claimed Fornataro off waivers from the Cardinals in November. He had a decent showing at Triple-A Memphis in 2014.
