The Rockies transferred Herrera (elbow) from the 15-day injured list to the 60-day IL on Monday.
Analysis:
Herrera landed on the 15-day IL on Saturday due to left elbow inflammation, but his move to the 60-day IL just two days later suggests that his injury is more severe that the Rockies initially anticipated. With Herrera set to remain on the shelf through at least late July, the Rockies were able to open up a spot on the 40-man roster for right-hander TJ Shook, whose contract was selected from Triple-A Albuquerque.
