The Washington Nationals, Baltimore Orioles and San Diego Padres are in need of a first baseman, and they’re going after one of the top two free agents available at the position, Derrek Lee and Adam LaRoche, according to sources close to Ken Rosenthal of FOXSports.

The Orioles recently acquired on of LaRoche’s good friends, third baseman Mark Reynolds and bench coach John Russell, so those reasons could persuade him to go there. The Nationals need a strong left-handed hitter to replace Adam Dunn, and the Padres appear as longshots for both first baseman.

Rosenthal speculates that the Texas Rangers, Toronto Blue Jays and the Arizona Diamondbacks could also be in on one of the first basemen.
