WASHINGTON -- The Nationals are one of three teams still in the hunt for free-agent infielder Greg Dobbs, who is expected to make a decision soon, according to a baseball source. The Marlins are reportedly another team involved in the hunt for Dobbs.

Nationals general manager Mike Rizzo was not available for comment, but if Dobbs is lured to the Nationals, he most likely would be the No. 1 pinch-hitter with occasional starts at third base and the corner-outfield spots.

The left-handed-hitting Dobbs, 33, is coming off one of his best seasons, hitting .275 with eight home runs and 49 RBIs for the Marlins.

Dobbs is best known for his days with the Phillies, whom he helped win a World Series title in 2008. That team also included Nationals outfielder Jayson Werth.

The Nationals are looking to improve their bench, which was one of the worst in baseball this past season, and manager Davey Johnson was not happy that it was built on speed and defense.

In 2012, Johnson wants bench players who can drive in runs. Dobbs can do that. Dobbs was 10-for-27 (.370) with a home run and eight RBIs as a pinch-hitter this past season.
