Troy E. Renck of The Denver Post says that the St. Louis Cardinals could have some interest in right-handed starting pitcher Aaron Cook.

Cook is owed roughly $14.25 million on his deal. Renck reminds us that the market for starters is really thin, so the former All-Star’s demand could increase the Rockies’ asking price.

The Phillies were in on Cook, but that’s out the window now that they acquired Roy Oswalt.

On Tuesday, Joel Sherman of the New York Post said the Colorado Rockies want to put Jhoulys Chacin back into the rotation, and so they are quietly shopping starting pitcher Cook. They are telling teams that they would either eat some dollars or take back a contract. The righty doesn’t have a no-trade clause in his contract, so the Rockies are free to move him to the highest bidder.

Cook, 31, is 4-6 with a 4.78 ERA in 19 starts this season.
