Whit required a spot on the 40 man roster as well, so in a corresponding move the Royals Designated Jose Martinez for assignment.
Colon was recently given the opportunity to receive more playing time at second base with the slow start Omar Infante has had this season. So far, Colon had only managed a slash of .262/.311/.310 causing the organization to possibly feel he is not the immediate answer either.
Merrifield has an .800 OPS with 5 homeruns for AAA Omaha, and had caught the eye of Ned Yost as a player to watch in spring training.
He is capable of playing all over the field, and has played all positions except short stop, pitcher and catcher thus far in 2016. He is the type of player that provides a little bit of a Ben Zobrist style of versatility and if his bat can be even mediocre, he may find himself playing quite a bit given the deficiencies the Royals have at both right field and second base.
Jose Martinez was thought by many to be close to cracking the roster for the Royals, but instead is DFA'd. He currently sits with a .298 batting average for AAA Omaha and has 3 home runs on the year.
