The Nationals reinstated Lovelady (triceps) from the 60-day injured list Saturday.
A triceps strain has kept Lovelady out since late June, but he began a rehab assignment Sept. 1 and has since allowed three earned runs while striking out four batters and walking one across 5.1 innings. Now fully healthy, he could enter the mix for high-leverage work with team saves leader Clayton Beeter heading back to Triple-A in a corresponding move.
