The Rockies have designated lefty Aaron Laffey for assignment, Nick Groke of the Denver Post tweets. The move clears space on the Rockies’ active roster for reliever Rex Brothers, who the Rockies are promoting from Triple-A Albuquerque.
The Rockies added Laffey to their roster only yesterday, and he allowed three runs in 2 1/3 innings yesterday against Atlanta in his first big-league outing since 2013. Earlier this season, he pitched 47 2/3 innings in a tough pitching environment in Albuquerque, posting a 4.91 ERA, 6.2 K/9 and 3.2 BB/9 while splitting time between starting and relieving.
