Cedeno, 28, allowed two runs on three hits in five relief appearances for the Nationals this season, with four strikeouts and two walks in three innings. Washington designated Cedeno for assignment on April 14.
He has been more of a lefty specialist, with 33 of his 77 career appearances facing two batters or less. In parts of five major league seasons with the Astros and Nationals, Cedeno has a 5.24 ERA and 4.30 FIP in 77 games, all in relief, with 54 strikeouts and 24 walks in 55 innings.
Left-handed batters have hit .252/.331/.351 against Cedeno in his career, with 39 strikeouts and nine walks in 126 plate appearances. Right-handers, by comparison, have hit .339/.409/.532 with 15 walks and 15 strikeouts.
The Dodgers will need to find room on the active roster for Cedeno because he is out of options, having used them in 2012 (with Houston) and 2013-2014 (with Washington). The left-hander entered the 2015 season with one year, 60 days of major league service time, and is making $516,500 this season.
To make room on the 40-man roster, the Dodgers designated Daniel Corcino for assignment. Corcino, a waiver claim from the , had a rough debut with Double-A Tulsa on Tuesday night. He retired just two of six batters faced, walking three and hitting a batter, throwing only 10 of 27 pitches for strikes. just last week
There is still a chance Corcino follows the same fate as his former Reds organization mate Ryan Dennick, if he clears waivers and is outrighted back to the minors.
