Left-hander Oliver Perez has signed a two-year, $7 million deal to join the Nationals’ bullpen, according to Jesse Sanchez of MLB.com.

Perez washed out as a starter because of his extreme control problems and came dangerously close to being totally out of the majors for good by age 30, but resurrected his career as a reliever and put together a strong run from 2012-2015.
