Team Hammer Releases Martin Cardenas

AMA Pro Racing’s Team Hammer has released Martin Cardenas from his contract to allow the reigning AMA Daytona Sportbike Champion “to better pursue his goal of returning to World Championship competition as soon as possible.” Though the eventual goal appears to be for Cardenas to move up to the World Superbike Championship, rumors have Cardenas landing with the Yoshimura Suzuki factory team to race in the AMA Superbike Championship in 2013 as an eventual stepping stone towards international racing. Cardenas won the 2010 and 2012 AMA Daytona Sportbike championships with Team Hammer riding a Suzuki GSX-R600. Team Hammer held a contract option for Cardenas for the 2013 season but decided to release the Colombian racer, allowing him to take a different route towards a WSBK career.
