The Nationals will select Blankenhorn's contract Friday, Jesse Dougherty of The Washington Post reports.
EDGE Analysis
Blankenhorn joined the Nationals on a minor-league deal in December, and he has spent the entire season with Triple-A Rochester. He's played well at the level as a 26-year-old, maintaining a 116 wRC+ across 452 plate appearances. He'll likely have to settle for a reserve role in the majors as a first baseman and corner outfielder.
