According to a tweet from FOX Sports' Ken Rosenthal, the Washington Nationals have agreed to sign free agent pitcher Dan Haren.
The move bolsters an already strong starting rotation and fills the void left by the departure of Edwin Jackson.
In the same tweet, Rosenthal noted that Haren will sign for one year and $13 million, pending the results of a physical.
Haren will join Cy Young finalist Gio Gonzalez, Stephen Strasburg, Ross Detwiler and Jordan Zimmermann in what is arguably the best starting rotation in the NL East if not the whole National League.
Rosenthal went on to tweet again that this move likely removes the Nationals from the list of suitors for starter Zack Greinke.
Haren struggled in 2012, pitching to a 12-3 record with a 4.33 ERA, a 1.29 WHIP and just 142 strikeouts to 38 walks in 176.2 innings pitched.
Haren is a three-time All-Star and has twice finished in the top 10 for Cy Young voting with the Angels and Diamondbacks. His signing should provide the Nationals with further depth in the starting rotation.
The move for Haren is the first major deal in what is sure to be an exciting few days for Major League Baseball at the Winter Meetings.
