Cook, 34, was recently released by the Phillies, and the Rockies had been expected to pursue him. Cook pitched for the Rockies from 2002 through 2011. He spent last season with the Red Sox, pitching 94 innings with a 5.65 ERA, 1.9 K/9 and 2.0 BB/9. Despite the extremely low strikeout rate, Saunders notes that Cook "believes he can still pitch in the major leagues if given a chance." He may have found the right organization to pursue that goal -- the Rockies, who recently signed Jon Garland to be their fifth starter, don't have a strong starting rotation.
