Corbin threw a bullpen session Friday, Jessica Camerato of MLB.com reports.

EDGE Analysis

The Nats' top three starters (Corbin, Max Scherzer and Stephen Strasburg) all got in work Friday as the club tries to quickly ramp up before Opening Day later this month. There was no indication of how many pitches Corbin was able to throw, however, so while GM Mike Rizzo described him as being in "full bullpen mode," how close he is to being ready for the regular season is still unclear.
