The Rockies added left-handed pitcher Tyler Anderson to their 40-man roster and designated right-handed pitcher Juan Nicasio for assignment on Thursday. Teams had until 9:59 p.m. MT on Thursday to set their 40-man rosters in advance of next month's Rule 5 Draft.
Anderson, 24 and Colorado's No. 12 prospect according to MLB.com, was originally selected by the Rockies in the first round (20th overall) of the 2011 First-Year Player Draft out of the University of Oregon. The 6-foot-4 left-hander spent the 2014 season at Double-A Tulsa, where he was named a Texas League All-Star and the league's Pitcher of the Year.
