The non-waiver trade deadline has passed, and the Phillies were subsequently unable to come to an agreement with the Cubs on a deal for Cole Hamels after Chicago reportedly claimed him last week.

But still, a blockbuster could be in the works.

The Phillies have been heavily scouting the Red Sox over these last two weeks, according to Nick Cafardo of the Boston Globe.

"Don’t think in 30 years of covering baseball I’ve ever seen a team (the Phillies) spend so much time scouting another team (the Red Sox) and not pull the trigger on a deal," Cafardo wrote in his Sunday notes column.

"Even after the trade deadline, the Phillies have had a scout in Boston, St. Louis, and Anaheim watching Boston’s young players. The match would be Cole Hamels for young players, and it may very well heat up this offseason. Hamels, according to a source close to him, would be open to a deal with the Red Sox."

There are few teams positioned to pull off a deal for Hamels. The Red Sox, Dodgers and Cubs stick out as three clear fits because of their deep pockets and flush farm systems.

Boston has numerous young pieces on the 25-man roster that could intrigue the Phillies, such as shortstop/third baseman Xander Bogaerts, centerfielder Jackie Bradley Jr. and catcher Christian Vasquez.
