Minor Moves: Wall, Castillo, Volstad, Burgos, Flores

Let’s run down the day’s minor moves:

• The Pirates announced the signing of righty Josh Wall and catcher Wilkin Castillo to minor league deals with spring invites. And the club also added righty Chris Volstad, per Matt Eddy of Baseball America (via Twitter). Wall, 28, logged just one unsightly inning last year with the Angels but threw 44 1/3 productive innings at Triple-A. Oddly enough, Castillo has spent most of his time in the minors as a backstop but played only left field and second base in brief big league time back in 2008-09. The true utility man has been playing in Mexico since 2012. Volstad, of course, was a fixture in the Marlins rotation from 2008-11, but has seen minimal action since an unsuccessful 2012 run with the Cubs.
• Right-hander Hiram Burgos is heading back to the Brewers, Eddy tweets. Burgos was a 40-man casualty in September, but will remain in the only professional organization he has known. The 27-year-old made one brief, unsuccessful stint in the bigs. He missed significant time last year due to shoulder surgery.
• One additional catcher is joining the Braves organization, Eddy tweets, with Jesus Flores signing a minor league deal. A five-year veteran of the division-rival Nationals, the 31-year-old has bounced around in the upper minors the last two years and will look to extend his career in Atlanta.
