Rockies add Amezaga, option Mortensen
The Colorado Rockies have purchased the contract of infielder Alfredo Amezega and optioned right-handed pitcherto Triple-A Colorado Springs. To make room on the 40-man roster, the Rockies designated pitcher Alan Johnson for assignment. Amezaga will be in uniform for the Rockies in the series opener against the Pittsburgh Pirates on Friday.
Amezaga, who was signed to a minor-league contract in the offseason but missed much of the early part of spring training with various minor injuries, was hitting .364 with eight doubles and 11 RBI for the Sky Sox. A switch-hitter who has played shortstop, left field and center field this season, Amezaga has played every infield and outfield position in the majors at one time. He last played in the major league since 2009 and missed most of the 2010 season with a knee injury.
Mortensen pitched eight shutout innings in two games for the Rockies after being recalled on April 18. He made his first appearance that same day with six shutout innings in relief of starter. He allowed two hits and two walks and struck out three in his two major-league appearances.
Johnson made his major-league debut for the Rockies in a spot start on April 17 and allowed five runs (four earned) in four innings. He is 1-0 with a 0.84 ERA in two starts for Colorado Springs. If he clear waivers, he could remain with the Rockies.
