The Rockies declined their 2012 option on righty Aaron Cook, tweets Jim Armstrong of the Denver Post. The Rockies will pay Cook a $500K buyout as opposed to the $11MM option. GM Dan O'Dowd says the door is open for Cook to return on a new contract.
With 72 wins, Cook is 14 ahead of Jason Jennings on the team's franchise leaderboard. Cook posted a 6.03 ERA, 4.5 K/9, 3.4 BB/9, 0.84 HR/9, and 55.1% groundball rate in 97 innings this year. He signed his extension after the '07 season. Cook battled shoulder, toe, and finger injuries in the following seasons, his innings totals declining each year.
