Davis threw a bullpen session Tuesday -- his first since undergoing Tommy John surgery, MLB.com's Bill Ladson reports.

Analysis:

The 28-year-old reliever threw 25 fastballs Tuesday and intends to throw three bullpen sessions a week for the next four weeks. The plan is to then move on to throwing batting practices before facing hitters soon after camp breaks. Davis wants to be ready to pitch out of the Nationals' bullpen by September, which illustrates his lack of fantasy value heading into 2015.
