The Diamondbacks have traded 24-year old switch hitting catcher Wilkin Castillo to the Reds as one of the players to be named later in the Adam Dunn trade. Castillo was the #14 prospect in the D-Backs minor league system coming into the season according to Baseball America. Castillo has played in 104 games in AAA-ball this season and he is 98 for 386 (.254 avg, .663 OPS) with 40 runs scored, 6 homers, 47 RBIs and 4 stolen bases. He will probably get called up by the Reds when rosters expand.
