The Nationals sign Brian Dozier, who admits he was hurt in 2018:

He didn’t miss any time due to the injury (and has still never been on the DL), but Dozier has acknowledged to the media that a right knee bone bruise — and the manner in which he compensated for it, mechanically — impacted his 2018 production. Dozier had the worst full big-league season of his career, slashing .215/.305/.391 and playing sluggish defense. The league-average line at second base in 2018 was just .254/.317/.395, so if there’s any dead-cat bounce in Dozier at all, he’s probably still an average regular going forward. Obviously, though, a return close to what he has shown for the last four years means he has a chance to be an All Star.

So the Nationals get a player with huge upside potential for 2019. As Craig Edwards notes in the article, the Nationals improved themselves a great deal this off-season. One reason Bryce Harper may be leaning to return to Washington is that it may be the best place for him to play to win a championship.
