Before agreeing to terms with James Shields, the Padres made an “aggressive offer” to the Phillies for lefty Cole Hamels, Ken Rosenthal of FOX Sports reports. San Diego had long been said to be pursuing both arms.

Though the precise parameters of the offer are not known, Rosenthal indicates that Philadelphia may not feel that the San Diego system has a sufficiently promising single prospect asset to warrant Hamels. It is not clear whether the Padres have any continued interest in working out a deal, though it seems somewhat unlikely that sufficient payroll flexibility remains.

The Phillies prefer to deal with the Red Sox, per Rosenthal, hoping to land either Mookie Betts or Blake Swihart in return. But Boston has not made such an offer, he adds, making a deal seem unlikely unless the Red Sox “reverse course.”
