Haren’s new deal with the Nationals is pending a physical, according to Rosenthal. He adds that when the Los Angeles Angels declined the right-hander’s $15.5 million option for 2013 he received a $3.5 million buyout. With the $13 million he’ll earn with Washington he’ll "come out ahead," in the words of Rosenthal.

While he has started at least 30 games at the major league level since the 2005 season, there was concern regarding Haren’s back injury entering the offseason. Many teams were reportedly reviewing his medical records closely before making a decision on whether or not to pursue the right-hander.

Last season over 30 starts for the Angels Haren maintained an ERA of 4.33. In 10 seasons at the major league level the 32-year-old posted an ERA of 3.66 with 7.6 strikeouts and 1.9 walks per nine innings.

With the addition of Haren, the Nationals now boast a formidable starting rotation that also includes Stephen Strasburg, Gio Gonzalez and Jordan Zimmermann.
