The Diamondbacks have outrighted Sean Burroughs, Alberto Castillo and Robby Hammock to Triple-A, according to the CBSSports.com MLB transactions page. MLBTR's Tim Dierkes identified Burroughs and Hammock as likely non-tender candidates in his look at Arizona's arbitration-eligible players on Tuesday. Burroughs is going through the arb process for the second time, while Hammock is going through his first.
Burroughs appeared in 78 games with the D'Backs in 2011, his first taste of Major League action since 2006 and has already been outrighted once this season. Burroughs was taken by the Padres with the ninth overall pick of the 1998 draft but never lived up to expectations, posting a career slash line of .280/.337/.357 in 1805 plate appearances.
Castillo, 36, has a career ERA of 4.33 in 79 appearances over four seasons with the D'Backs and Orioles. The left-hander was designated for assignment by Baltimore in June and then signed a minor league deal with Arizona a week later.
Hammock was in his third stint as a Diamondback and, though he has also been part of the Yankees, Rockies and Orioles organizations, has only appeared in the Major Leagues with Arizona. Hammock, 34, has primarily played catcher in his career but has also logged time at third base, first base and in the outfield. The veteran has a .719 OPS in 527 career plate appearances over six seasons in the bigs.
