Aaron Cook likely to rejoin Rockies rotation in early September

On the disabled list for the past few weeks with a sprained big toe, Aaron Cook could rejoin the Rockies’ rotation as soon as September 2 against the Phillies. Cook tossed five innings of one-run ball Monday in his first rehab start at Triple-A and Troy Renck of the Denver Post reports that he’ll likely be asked to pitch once more in the minors before the Rockies make a decision on his status. Colorado unsuccessfully shopped Cook at the trade deadline, with other teams shying away in part because of his medioce performance this season and part because he’s still owed $9.25 million in 2011 with an $11 million option or $500,000 buyout for 2012. He suffered the toe injury just a few days after the deadline passed.
