Veteran first baseman Nathaniel Lowe, 30, designated for assignment by the Washington Nationals earlier this month, and the Boston Red Sox are finalizing a deal, sources told ESPN, paving the way for him to join one of the strongest lineups in baseball.

The Boston Red Sox are signing slugging first baseman Nathanial Lowe after he had been designated for assignment by the Nationals last week in favor of younger players, ESPN.com reported. Lowe, 30, will join one of the most potent offenses in baseball with Boston in the midst of a tight American League playoff race.

Still, Lowe has hit 17 doubles, 16 homers and driven in 68 runs while walking at a decent rate. He's 30 years old and has previously won a Gold Glove and a Silver Slugger award. This is a big fella with a sweet left-handed swing who can also field his position.
