The deal he signed with the Braves in 2011 came after a 2010 season with the then-Florida Marlins in which he put up a .287/.369/.508 line with 31 doubles and 33 HRs in 159 games and 674 PAs over which he was worth +4.5 fWAR.
In the four seasons that followed, the second baseman posted a combined .208/.316/.388 line with 64 doubles and 79 HRs in 503 games and 1,996 plate appearances.
He finished at +2.2 fWAR in 2011, +3.3 in 2012, +0.4 in '13.
Uggla had a .162/.241/.231 line with three doubles and two home runs when he was released last July.
He signed with San Francisco, and played four games with Giants last season, but was released again in August.
The Washington Nationals announced that they signed the veteran infielder to a minor league deal this morning:
The Nationals have signed three veterans to minor league deals in the last two weeks, bringing reliever Heath Bell and infielder Ian Stewart into the organization.
Uggla has history with the Nationals' GM Mike Rizzo, of course, having been drafted by the Arizona Diamondbacks in the 11th Round of the 2001 Draft while Rizzo was the scouting director for the D-Backs.
