The Kansas City Royals officials website tweeted out the news:
The 26-year-old Peter 0’Brien slammed 50 total home runs the his last two AAA seasons, including slashing .254/.295/.505 with 24 dingers at Reno of the Pacific Coast League last season. O’Brien joined the Diamondbacks organization as a catcher after Arizona drafted him in the third round of the 2011 draft.
The former Bethune Cookman collegiate player has transitioned to the outfield while playing some first base the last couple of seasons. Frankly, Arizona has been trying to find a defensive position for the 6’4″ 235 pound 0’Brien.
