The Blue Jays released first baseman David Cooper, Jon Heyman of CBSSports.com reports (on Twitter). The CAA Sports client is now a free agent.

Cooper has missed Spring Training with a serious back injury. The injury could lead to a season of rehabbing and might even end his career, Joel Sherman of the New York Post writes (on Twitter). Sherman suggests the Blue Jays might try to sign Cooper to a minor league deal with an eye toward a 2014 return and Jon Heyman of CBSSports.com confirms that the Blue Jays have interest in re-signing Cooper (Twitter link).

Cooper, 26, appeared in 45 games for the 2012 Blue Jays as a first baseman and designated hitter. He posted a .300/.324/.464 batting line in 145 plate appearances, including four home runs. All six of the left-handed hitter's career home runs have come against right-handed pitching. Cooper, the Blue Jays' first round pick in 2008, has less than one year of MLB service time (136 days).
