In order to make room on the 40-man roster for Adcock, the Rangers transferred first baseman Mitch Moreland to the 60-day disabled list. Moreland has not played since June 7, and underwent ankle surgery shortly thereafter.
Adcock made 36 appearances with the Royals in 2011 and 2012. He spent 2013 in Triple-A in both the Diamondbacks and Royals systems. He signed as a free agent with the Rangers prior to this season. Adcock made 13 appearances for Triple-A Round Rock this season, accumulating a 2.76 ERA and 0.980 WHIP.
