De La Rosa suffered a torn ulnar collateral ligament in his left elbow in May of 2011 and had not pitched since, requiring Tommy John surgery to repair the tear. The veteran pitcher returned late in the 2012 season, making three starts while recording a 9.28 ERA in 10⅔ innings of work during his return.
The veteran of nine years made his debut in 2004 with the Milwaukee Brewers and, after a brief stint in Kansas City, was traded to the Rockies in April of 2008. De La Rosa, who has a career ERA of 4.96, was enjoying a hot start in 2011 prior to his season-ending injury.
De La Rosa will be paid $11 million in 2013, with the Rockies now owning a club option for the pitcher for 2014 worth $11 million.
