Following Thursday's game against the Giants, the Nationals activated outfielder Lastings Milledge from the 15-day disabled list and designated catcher Johnny Estrada for assignment.

The news comes almost 30 minutes after Estrada called a great game in a 1-0 defeat. The Nationals had four catchers on the 25-man roster, and some one had to go.
