The D'Backs announced that they released Carlos Rosa to sell him to a Japanese team. Rosa, 26, is out of options, so he would have had to clear waivers before going to the minor leagues.
Rosa appeared in 22 games for the D'Backs last year, allowing 20 hits and 12 walks in 20 innings while striking out nine. He had cameos with the Royals in 2008 and '09, but most of his pro experience comes in the minors, where he has a 3.54 ERA with 7.3 K/9 and 3.3 BB/9 in 623 2/3 innings.
Nick Piecoro of the Arizona Republic first reported the move (on Twitter).
