Patterson pitched seven shutout innings April 21 against the Braves, but got the no-decision as the Nationals lost, 2-1. He has struggled with a 6.75 ERA in May.
Braves left-hander Mike Hampton is also expected to make a return from the disabled list. The southpaw has been out with a strained left forearm since May 15.
Hampton lasted only 2 1/3 innings in his last start before getting hurt, but tossed a complete-game, two-hit shutout against Houston in his previous turn. He pitched eight innings of one-run ball against the Nats in an 11-2 win April 11 at Turner Field.
Marlon Byrd hit two RBI doubles Monday to support Tomo Ohka and push the Nationals to a 3-2 win before a Memorial Day crowd of 39,705.
After the game the Nats activated Patterson and outfielder Wil Cordero, and optioned Tyrell Godwin and Brendan Harris to Triple-A New Orleans.

Player to watch
At .375, left-handed hitting Brad Wilkerson has the team's best batting average against lefties this season [of players with at least 20 at-bats against them]. Entering the series, the Nationals were hitting just .256 against lefties.
"It's good for the Rolaids and Tums people. It can be enough if you're getting this good of pitching, but it's like walking a tight rope. -- manager Frank Robinson, on his team being able to win when scoring just three runs
