The Washington Nationals have designated catcher Johnny Estrada for assignment. He played in 23 games for the Nationals this season and he was 9 for 53 (.170 avg, .370 OPS) with 0 runs scored and 4 RBIs. The Nationals’ didn’t feel the need to carry 4 catchers anymore and Jesus Flores, Wil Nieves and Paul LoDuca are all ahead of Estrada on the depth chart. Maybe the Marlins or Astros will have some interest in Estrada. The Nationals have activated outfielder Lastings Milledge from the D.L. Milledge has played in 80 games this season for the Nationals and he is 74 for 302 (.245 avg, .680 OPS) with 35 runs scored, 7 homers, 32 RBIs and 13 stolen bases.
