The Royals on Wednesday selected the contracts of right-handed pitchers Seth Maness and Al Alburquerque from Class AAA Omaha.
To clear space on the 40-man roster, the Royals designated infielder Christian Colon, who was on the 25-man roster, and first baseman/outfielder Pete O’Brien, who was in Omaha, for assignment. The Royals also optioned pitcher Jake Junis back to Omaha.
