KANSAS CITY -- Former Royals infielder Christian Colon, who was designated for assignment last week, has been claimed by the Marlins.
Meanwhile, outfielder Peter O'Brien, also DFA'd by the Royals last week, has been claimed by the Reds.
Colon, the fourth overall pick of the 2010 Draft, hit .176 in seven games for the Royals this season.
"I appreciated his competitiveness," manager Ned Yost said. "And he was just a tremendous teammate in that room."
Added left-hander Danny Duffy, "I know he's going to miss the boys in this room, but this is a great opportunity for him."
O'Brien played in 27 games for the Royals' Triple-A affiliate in Omaha, hitting .162 with three home runs and six RBIs.
