Erik Davis, 28, was placed on the 60-Day DL with a right elbow sprain early in Spring Training last February and the right-hander underwent Tommy John surgery in the first week of April.
Taylor Jordan started the 2014 campaign in the Washington Nationals' rotation, but after struggling and losing velocity in the first month, he was sent to Triple-A Syracuse.
Washington Post writer Adam Kilgore reported earlier this week that the 25-year-old, '09 9th Round pick underwent surgery to remove bone chips from his right elbow in September.
Nate McLouth, 33, signed a 2-year/$10.75M deal with the Nats last winter, but played just 79 games for the Nationals this season, putting up a .173/.280/.237 line in 162 plate appearances before he was shut down with what was later diagnosed as a torn labrum in his right shoulder.
Matt Purke, 24, and a 2011 3rd Round pick by the Nationals, returned from shoulder surgery in 2013, and was set for a big season which started at Double-A Harrisburg, but the left-hander struggled through eight starts, putting up an 8.04 ERA in 31 ⅓ IP before he was shut down for the season with what was later diagnosed as a torn ulnar collateral ligament in his left elbow.
Purke underwent Tommy Surgery in late May. In late July, Purke, who signed a major league deal when he was drafted, was placed on the 60-Day DL.
All four were reinstated from the 60-Day DL by the Nationals this afternoon, leaving the Nats with 39 men on the 40-Man Roster:

Today's moves were the latest Washington has made in the last two days.
Yesterday the Nationals picked up Denard Span's option for 2015 while declining the options for Adam LaRoche and Rafael Soriano. As noted in the tweet above, there are now 39 players on the Nats' 40-Man roster.
