Rockies acquire pitcher from A’s, designate Deduno
The Colorado Rockies have acquired right-handed pitcherfrom the Oakland Athletics for minor-league pitcher Ethan Hollingsworth. To make room on the 40-man roster, the team designated pitcher for assignment.
Mortenson, 25, was a supplemental first-round pick by the St. Louis Cardinals in 2007 and was later traded to the A’s as part of the deal that sent former Rockie Matt Holliday to the Cardinals. Mortenson made one start for the A’s in 2010 and has made might career appearances — seven starts — between his time with the Cardinals and the A’s, going 2-4 with a 7.12 ERA. At Triple-A Sacramento in 2010, Mortenson was 13-6 with a 4.25 ERA in 26 starts. He was rated the 10th-best prospect in the A’s system before the 2010 season.
He as was designated for assignment by the A’s last week when they signed Grant Balfour.
Hollingsworth, 23, was drafted by the Rockies in the fourth round of the 2009 draft. He pitched primarily at high Class-A Modesto in 2010, where he was 12-8 with a 3.31 ERA in 25 starts. He also made two starts at Double-A Tulsa where he was 0-0 with a 9.58 ERA.
Deduno, 27, made his major-league debut with the Rockies last season after an injury-plagued rise through the minor-league system. A starter most of his minor-league career, the Rockies viewed him as a reliever in the majors, which is how he was used in four appearances late in the 2010 season. He had a 3.38 ERA in 2 2/3 innings.
