Dan Haren allowed seven runs -- three earned -- in 4 1/3 innings Tuesday as the Nationals fell to the Marlins.

Haren didn't get much help from his defense but also looked far too hittable. The 32-year-old right-hander is now sporting a hideous 8.13 ERA, 2.03 WHIP and 12/1 K/BB ratio over his first 13 1/3 innings with the Nationals. Bench him for now in fantasy leagues.

Dan Haren won Thursday despite allowing three runs and 10 hits in five innings against the White Sox.

At least Haren didn't give up any homers tonight. He got some help there from a nice breeze blowing in from center. He ended up striking out five and walking none. He's not the Dan Haren of old, but given that he's on such a good team and his tiny walk rate will result in a solid WHIP, no one should be thinking of dropping him in mixed leagues.

Dan Haren was smoked for six runs on four home runs over four innings in a loss to the Reds on Friday night.

Haren's spring training struggles have now crossed over to the regular season. While the veteran right-hander has always given up his fair share of fly balls -- a poor fit in Great American Ball Park -- he appeared way too hittable in this one. It's going to be tough to trust him in standard mixed leagues until he proves that he's healthy.

Dan Haren was tagged for four homers and five runs in six innings by the Marlins on Tuesday.

It's understandable that Haren gave up a pair of homers to Giancarlo Stanton. The shots from Chris Valaika and Chris Coghlan were less forgivable. Haren showed better velocity at the beginning of the spring than he has lately. With the way he's throwing now, there's a good chance he'll struggle in the early going.

Dan Haren surrendered four runs in 5 1/3 innings Thursday in a loss to the Braves.

Although the results didn't show it, Haren said his he felt much better tonight than he did in his loss last Friday to the Cardinals. According to CSN Washington's Mark Zuckerman, Haren regularly worked at 89 mph tonight and touched 91 mph. It's still not ideal, but it's an improvement over last time out.

Dan Haren gave up five runs in five innings Friday in a loss to the Cardinals.

Haren didn't have much on his fastball today, and he said afterwards that he felt achy. Perhaps he's going through his dead-arm phase. Haren didn't seem very concerned afterwards, so we won't be either, unless he fails to bounce back next time out.

Dan Haren was charged with two runs on five hits in four innings Sunday in a loss to the Tigers.

Haren was better than the line suggests; he didn't get much help from his defense in this one. He's had an encouraging spring, and it looks like the Nationals may have gotten a modest bargain when they signed him to a one-year, $13 million contract.

According to Nationals manager Davey Johnson, Dan Haren looked impressive during his first side session as a member of the Nationals on Friday.

Johnson noted that his stuff looked "really good" and that he had good command. Catcher Jhonatan Solano also gave him rave reviews, noting his ability to command the cutter while getting impressive movement on the pitch. Haren is coming off a highly disappointing and injury-riddled 2012 campaign, but could be poised for a big bounce-back effort in 2013.

Nationals signed RHP Dan Haren to a one-year, $13 million contract.

Haren passed his physical Friday -- which was no slam dunk -- to make the deal official. The veteran right-hander has dealt with back and hip issues and declining velocity over the last few years, but he's a nice gamble for the Nats on a one-year deal. He'll slot in behind Stephen Strasburg, Gio Gonzalez and Jordan Zimmermann and ahead of Ross Detwiler in the Nats' formidable rotation.

FOX Sports' Ken Rosenthal reports that the Nationals and Dan Haren have agreed to a one-year, $13 million contract, pending a physical.
