The Nationals look like they might be going the quantity over quality route in attempting to address first base, first adding Juan Yepez
and now Diaz as non-roster invitees. Diaz posted an .804 OPS with 17 homers over 118 games for the Orioles' Triple-A affiliate in Norfolk but didn't see any time in the majors. He'll get a shot this spring to win an Opening Day roster spot.
