The Red Sox are 44-55 through 99 games this season.

The non-waiver trade deadline comes on Friday, so be prepared for five days of rumors and quite likely at least some minor deals by the last-place Red Sox.
They should be active, whether it’s selling or buying, as evidenced by Monday’s trade of Shane Victorino to the Angels. A poorly constructed roster needs some changes. At 44-55, the Red Sox are again in a position of getting ready for next season and that means culling the roster of older players who will be free agents after the season.

The Sox do not have as much to offer as they did last season, but there are a few players who will generate interest. Here is an assessment of the players on the 40-man roster and what their trade value is at the moment:
Best trade chip
Koji Uehara: The reliable closer has $12.5 million left on a two-year deal that extends through 2016, so the Red Sox might have to pick some of that up to improve the return. Whether it’s as a set-up man or closer, Uehara would instantly improve a contending team and there is interest in him.
If the Sox think they will contend next season, they’ll probably keep Uehara.
Lesser trade chips

Pirates reportedly eye Mike Napoli, Shane Victorino
The veterans could provide a strong clubhouse presence for a contending ballclub.

Joe Kelly: Kelly has a 5.03 ERA in 25 starts for the Red Sox since being obtained from the Cardinals a year ago. He should be in the bullpen. Maybe some other team thinks so.
Mike Napoli: He has $6.22 million left on his contract and the Sox would have to pick up the bulk of that to make a trade. He could help a team as a DH or first baseman. His recent hot streak — 10 of 25 in his last seven games with five extra-base hits and five RBIs — has come at the right time.

Justin Masterson has a 5.64 ERA in 52.2 innings pitched this season.

Trade throw-ins
Craig Breslow: The lefty has been traded twice before. Poor results the last two seasons have squashed any trade value he once had.
Alejandro De Aza: He has struggled since the All-Star break (4 for 24) but some team out there might want to improve its outfield depth.
Tommy Layne: Lefty specialist has …Read More
