The Marlins have been aggressively looking to deal starting pitcher Ricky Nolasco, but they might have been too demanding, according to FOX Sports.

Sources said the Marlins are looking for prospects that possess upside in return for the veteran right-hander. Sources added the Marlins also want the trading partner to absorb most or all of the remaining $5.7 million left on Nolasco's contract.

According to sources, the Rockies agreed to send the Marlins two quality prospects if the Marlins included cash in the trade. The Marlins balked and the Rockies lost interest.

Sources said the Dodgers are willing to absorb Nolasco's contract, but only at a minimal cost in talent. The Rangers, Giants and Padres have also expressed interest in trading for Nolasco, who the Marlins were looking to deal before his Wednesday start at Atlanta.
